• This Is the ‘Worst Food Ingredient for Your Immune System'—Especially During Covid, Says Immunologist - NBC, 1/15/22 - "As an allergist and immunologist, I frequently tell my patients that having diabetes means you're in a chronic low-grade inflammatory state, which taxes the body's innate immune system and makes it slower to jump on pathogens when they enter the body ... When it comes to our immune system, what we eat matters a lot. And no ingredient is more detrimental to your immune health than sugar, especially during Covid ... When you have high blood sugar — which is caused by many factors, but the biggest is consuming too much of it in your diet — it starts a vicious cycle of insulin resistance and obesity that drives up inflammatory cytokines, damages blood vessels, and activates the immune system to repair those areas ... This creates a major distraction for the immune system and paves the way for dangerous bacteria and viruses to slip through our body's defenses"

• Lactoferrin for Mental Health: Neuro-Redox Regulation and Neuroprotective Effects across the Blood-Brain Barrier with Special Reference to Neuro-COVID-19 - J Diet Suppl 2021 May 12 - "Overall mental health depends in part on the blood-brain barrier, which regulates nutrient transfer in-and-out of the brain and its central nervous system. Lactoferrin, an innate metal-transport protein, synthesized in the substantia nigra, particularly in dopaminergic neurons and activated microglia is vital for brain physiology. Lactoferrin rapidly crosses the blood-brain barrier via receptor-mediated transcytosis and accumulates in the brain capillary endothelial cells. Lactoferrin receptors are additionally present on glioma cells, brain micro-vessels, and neurons. As a regulator of neuro-redox, microglial lactoferrin is critical for protection/repair of neurons and healthy brain function. Iron imbalance and oxidative stress are common among patients with neurodegenerative disorders such as Parkinson's disease, Alzheimer's disease, dementia, depression, and multiple sclerosis. As an endogenous iron-chelator, lactoferrin prevents iron accumulation and dopamine depletion in Parkinson's disease patients. Oral lactoferrin supplementation could modulate the p-Akt/PTEN pathway, reduce Aβ deposition, and ameliorate cognitive decline in Alzheimer's disease ... Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections are widely reported in Parkinson's disease, Alzheimer's disease, dementia, and multiple sclerosis patients with aggravated clinical outcomes.

• Zinc deficiency as a possible risk factor for increased susceptibility and severe progression of COVID-19 - Br J Nutr 2021 Mar 1;1-42 - "The importance of zinc for human health becomes obvious during zinc deficiency. Even mild insufficiencies of zinc cause alterations in haematopoiesis and immune functions, resulting in a pro-inflammatory phenotype and a disturbed redox metabolism. Although immune system malfunction is the most obvious effect, the functions of several tissue cell types are disturbed if zinc supply is limiting. Adhesion molecules and tight junction proteins decrease while cell death increases, generating barrier dysfunction and possibly organ failure. Taken together, zinc deficiency both weakens the resistance of the human body towards pathogens and at the same time increases the danger of an overactive immune response that may cause tissue damage.The case numbers of COVID-19 are still increasing, which is causing enormous problems for health systems and economies. There is an urgent need to reduce both the number of severe cases and the resulting deaths. While therapeutic options are still under investigation,and first vaccines have been approved, cost-effective ways to reduce the likelihood of or even prevent infection, and the transition from mild symptoms to more serious detrimental disease, are highly desirable.

• Vitamin D Deficiency and Low Serum Calcium as Predictors of Poor Prognosis in Patients with Severe COVID-19 - J Am Coll Nutr 2021 Jan 12 - "Hypovitaminosis D and hypocalcemia were very common, occurring in 75% and 35.8% of patients. When analyzing survival, both were significantly associated with in-hospital mortality in a dose-effect manner (pLog-Rank = 0.009 and 0.001 respectively). A cutoff value of 39 nmol/l for vitamin D and 2.05 mmol/l for corrected calcemia could predict poor prognosis with a sensitivity of 76% and 84%, and a specificity of 69% and 60% respectively. Hazard ratios were (HR = 6.9, 95% CI [2.0-24.1], p = 0.002 and HR = 6.2, 95% CI [2.1-18.3], p = 0.001) respectively ... This study demonstrates the high frequency of hypocalcemia and hypovitaminosis D in severe COVID-19 patients and provides further evidence of their potential link to poor short-term prognosis.

• Vitamin K metabolism as the potential missing link between lung damage and thromboembolism in Covid-19 - Br J Nutr 2020 Oct 7;1-25 - "Coronavirus disease 2019 (Covid-19), caused by SARS-CoV-2, exerts far-reaching effects on public health and socioeconomic welfare. The majority of infected individuals have mild to moderate symptoms but a significant proportion develops respiratory failure due to pneumonia. Thrombosis is another frequent manifestation of Covid-19 that contributes to poor outcomes. Vitamin K plays a crucial role in activation of both pro- and anticlotting factors in the liver, and the activation of extrahepatically synthesised protein S which seems to be important in local thrombosis prevention. However, the role of vitamin K extends beyond coagulation. Matrix Gla protein (MGP) is a vitamin K-dependent inhibitor of soft tissue calcification and elastic fibre degradation. Severe extrahepatic vitamin K insufficiency was recently demonstrated in Covid-19 patients, with high inactive MGP levels correlating with elastic fibre degradation rates. This suggests that insufficient vitamin K-dependent MGP activation leaves elastic fibres unprotected against SARS-CoV-2 induced proteolysis. In contrast to MGP, Covid-19 patients have normal levels of activated factor II, in line with previous observations that vitamin K is preferentially transported to the liver for activation of procoagulant factors. We therefore expect that vitamin K-dependent endothelial protein S activation is also compromised, which would be compatible with enhanced thrombogenicity. Taking these data together, we propose a mechanism of pneumonia-induced vitamin K depletion, leading to a decrease in activated MGP and protein S, aggravating pulmonary damage and coagulopathy, respectively" - [Nutra USA] - See vitamin k2 at Amazon.com and iHerb.

• Vitamin D can be effective on the prevention of COVID-19 complications: A narrative review on molecular aspects - Int J Vitam Nutr Res 2020 Aug 19 - "An arguable role in autophagy or apoptosis control has been suggested for VD through calcium signaling at the mitochondrial and ER levels. 1,25(OH)2D3 is also an immunomodulator that affects the development of B-cells, T-cells, and NK cells in both innate and acquired immunity. The production of some anti-microbial molecules such as defensins and cathelicidins is also stimulated by VD. The overexpression of glutathione, glutathione peroxidase, and superoxide dismutase, and down-regulation of NADPH oxidase are induced by VD to reduce the oxidative stress. Moreover, the multi-organ failure due to a cytokine storm induced by SARS-CoV2 in COVID-19 may be prevented by the immunomodulatory effects of VD. It can also downregulate the renin-angiotensin system which has a protective role against cardiovascular complications induced by COVID-19. Given the many experimental and molecular evidences due to the potential protective effects of VD on the prevention of the COVID-19-induced morbidities, a VD supplementation is suggested to prevent the lethal side-effects of the infection. It is particularly recommended in VD-deficient patients or those at greater risk of serious or critical effects of COVID-19, including the elderly, and patients with pre-existing chronic diseases, especially those in nursing homes, care facilities, and hospitals" - See vitamin D at Amazon.com and iHerb.

• Rationale for the use of N-acetylcysteine in both prevention and adjuvant therapy of COVID-19 - FASEB J 2020 Aug 11 - "COVID-19 may cause pneumonia, acute respiratory distress syndrome, cardiovascular alterations, and multiple organ failure, which have been ascribed to a cytokine storm, a systemic inflammatory response, and an attack by the immune system. Moreover, an oxidative stress imbalance has been demonstrated to occur in COVID-19 patients. N- Acetyl-L-cysteine (NAC) is a precursor of reduced glutathione (GSH). Due to its tolerability, this pleiotropic drug has been proposed not only as a mucolytic agent, but also as a preventive/therapeutic agent in a variety of disorders involving GSH depletion and oxidative stress. At very high doses, NAC is also used as an antidote against paracetamol intoxication. Thiols block the angiotensin-converting enzyme 2 thereby hampering penetration of SARS-CoV-2 into cells. Based on a broad range of antioxidant and anti-inflammatory mechanisms, which are herein reviewed, the oral administration of NAC is likely to attenuate the risk of developing COVID-19, as it was previously demonstrated for influenza and influenza-like illnesses. Moreover, high-dose intravenous NAC may be expected to play an adjuvant role in the treatment of severe COVID-19 cases and in the control of its lethal complications, also including pulmonary and cardiovascular adverse events." - See N-acetyl cysteine at Amazon.com and iHerb.

• Metformin in COVID-19: A Possible Role Beyond Diabetes - Diabetes Res Clin Pract. 2020 Apr 29 - "The mammalian target of rapamycin (mTOR) signalling plays an important role in the pathogenesis of influenza, besides modulating antibody response for cross-protective immunity against infective influenza viruses. Metformin activates AMPK via liver kinase B1 (LKB1), inhibiting the mTOR pathway. It also indirectly attenuates AKT activation through phosphorylation of insulin receptor substrate 1 (IRS-1) resulting in inhibition of the mTOR signalling cascade [11]. Other biguanide molecules, buformin and phenformin have been associated with better survival outcomes in animal models of influenza [12,13]. Further, the PI3K/AKT/mTOR pathway plays major roles in MERS CoV infection [14]. Since metformin inhibits the same pathway, it would be interesting to decipher its role against SARS-CoV-2" - See metformin at ReliableRxPharmacy.

• Reduced Vitamin K Status as A Potentially Modifiable Prognostic Risk Factor in COVID-19 - pharmacology & toxicology 24 Apr 2020 - "We hypothesized that vitamin K status is reduced in patients with severe COVID-19. Methods: Vitamin K status was assessed by measuring desphospho-uncarboxylated matrix Gla protein (dp-ucMGP; inversely related to vitamin K status) and the rate of elastin degradation by measuring desmosine. We included 123 patients who were admitted with COVID-19 and 184 controls. Results: Dp-ucMGP levels were significantly elevated in COVID-19 patients (1,673Å}1,584 pmol/L) compared to controls (536±291 pmol/L; p<0.0005). Dp-ucMGP levels were significantly higher in COVID-19 patients with unfavorable outcome compared to those with less severe disease. Furthermore, dp-ucMGP and desmosine levels were significantly associated (r=0.65; p<0.0005). Conclusions: Vitamin K status was reduced in patients with COVID-19 and related to poor prognosis. Also, low vitamin K status seems to be associated with accelerated elastin degradation. An intervention trial is now needed to assess whether vitamin K administration improves outcome in patients with COVID-19" -  [Nutra USA] - See vitamin K at Amazon.com and vitamin K at iHerb.com.

• Editorial: low population mortality from COVID‐19 in countries south of latitude 35 degrees North supports vitamin D as a factor determining severity - Alimentary Pharmacology and Therapeutics, 20 Apr 2020 - "Evidence that vitamin D might protect against infection is modest but it is important to note that the hypothesis is not that vitamin D would protect against SARS‐CoV‐2 infection but that it could be very important in preventing the cytokine storm and subsequent acute respiratory distress syndrome that is commonly the cause of mortality ... Research is urgently needed to assess whether there may be a correlation between vitamin D status and severity of COVID‐19 disease. Meanwhile, the evidence supporting a protective effect of vitamin D against severe COVID‐19 disease is very suggestive, a substantial proportion of the population in the Northern Hemisphere will currently be vitamin D deficient, and supplements, for example, 1000 international units (25 micrograms) per day are very safe.

On the fifth day, 70 percent of the zinc lozenge patients had recovered compared with 27 percent of the placebo patients ... The dose of zinc in the three studies was between 80 to 92 mg/day ... Even though there is strong evidence that properly formulated zinc acetate lozenges can increase the rate of recovery from the common cold by 3 fold, many zinc lozenges on the market appear to have either too low doses of zinc or they contain substances that bind zinc ions, such as citric acid" - See zinc acetate lozenges at Amazon.com.
• Common cold duration is shortened similarly by zinc acetate and zinc gluconate lozenges - Science Daily, 5/3/17 - "Three trials had used zinc acetate lozenges and found that colds were shortened on average by 40%. Four trials had used zinc gluconate lozenges and colds were shortened on average by 28%. The 12% difference between the average effects of the two kinds of lozenges was explained purely by random variation. Furthermore, one of the zinc gluconate lozenge trials was an outlier inconsistent with all the other six zinc lozenge trials. If that outlier trial was excluded, the difference between the three zinc acetate and the three zinc gluconate trials shrinked to just 2%, i.e., a 40% vs. 38% reduction in common cold duration. Thus, properly composed zinc gluconate lozenges may be as effective as zinc acetate lozenges"

• Immunomodulatory Activity of Red Ginseng against Influenza A Virus Infection - Nutrients. 2014 Jan 27;6(2):517-29 - "We investigated whether red ginseng extract (RGE) has preventive effects on influenza A virus infection in vivo and in vitro. RGE was found to improve survival of human lung epithelial cells upon influenza virus infection. Also, RGE treatment reduced the expression of pro-inflammatory genes (IL-6, IL-8) probably in part through interference with the formation of reactive oxygen species by influenza A virus infection. Long-term oral administration of mice with RGE showed multiple immunomodulatory effects such as stimulating antiviral cytokine IFN-γ production after influenza A virus infection. In addition, RGE administration in mice inhibited the infiltration of inflammatory cells into the bronchial lumens. Therefore, RGE might have the potential beneficial effects on preventing influenza A virus infections via its multiple immunomodulatory functions" - See ginseng at Amazon.com.

• Vitamin D may protect against viral infections during the winter - Science Daily, 4/30/12 - "insufficient levels of vitamin D are related to a deficiency in our innate immune defenses that protect us from infections, neoplasias or autoimmune diseases. Since vitamin D levels decrease during autumn and winter when days are shorter and sunlight is relatively weak, this may explain why people are more prone to viral infection during these times. It also suggests that increased vitamin D intake, especially in older populations, could strengthen people's innate immunity against viral infections ... the researchers compared the changes in the blood levels of vitamin D among three groups of healthy subjects: young (age range: 20-30), middle (age range: 31-59), and elderly (age range: 60-86). They found decreased levels of vitamin D with aging, prompting researchers to compare whether such changes kept any relationship with toll-like receptor (TLR) expression measured on lymphocytes and monocytes and function after in vitro stimulation with specific ligands for each of the nine human TLRs and measurement of effector molecules, such as proinflammatory cytokines. Specifically, they found that the TRL most affected by a vitamin D insufficiency is TLR7, which regulates the immune response against viruses" - See vitamin D at Amazon.com.

• Study links severe COVID-19 disease to short telomeres - Science Daily, 1/11/21 - "It is known that telomere length is an indicator of ageing: each time a cell divides, its telomeres shorten until they can no longer perform their protective function and the cell, which now becomes damaged, stops dividing. Throughout life, cells are constantly dividing to regenerate tissues, and when they stop doing so because the telomeres are too short, the body ages ... In recent years, researchers have shown in mice that it is possible to reverse this process by activating the production of telomerase, which is the enzyme in charge of making the telomeres longer. In animals, telomerase activation is effective in treating diseases associated with ageing and telomere damage, such as pulmonary fibrosis ... What could not be foreseen, and this is the most important finding, is that the telomeres of the most seriously ill patients were also shorter, irrespective of age"

• The End of the Pandemic Is Now in Sight - Atlantic, 11/18/20 - "mRNA vaccines offer a clever shortcut. We humans don’t need to intellectually work out how to make viruses; our bodies are already very, very good at incubating them. When the coronavirus infects us, it hijacks our cellular machinery, turning our cells into miniature factories that churn out infectious viruses. The mRNA vaccine makes this vulnerability into a strength. What if we can trick our own cells into making just one individually harmless, though very recognizable, viral protein? The coronavirus’s spike protein fits this description, and the instructions for making it can be encoded into genetic material called mRNA ... Both vaccines, from Moderna and from Pfizer’s collaboration with the smaller German company BioNTech, package slightly modified spike-protein mRNA inside a tiny protective bubble of fat. Human cells take up this bubble and simply follow the directions to make spike protein. The cells then display these spike proteins, presenting them as strange baubles to the immune system. Recognizing these viral proteins as foreign, the immune system begins building an arsenal to prepare for the moment a virus bearing this spike protein appears."
• Early Data Suggests Moderna's COVID-19 Vaccine Is Nearly 95% Effective—And You Can Keep It in the Fridge - Time, 11/16/20 - "On Sunday, an independent monitoring board broke the code to examine 95 infections that were recorded starting two weeks after volunteers’ second dose — and discovered all but five illnesses occurred in participants who got the placebo. ... All 11 severe COVID-19 cases were among placebo recipients, and there were no significant safety concerns ... The main side effects were fatigue, muscle aches and injection-site pain after the vaccine’s second dose, at rates that Hoge characterized as more common than with flu shots but on par with others such as shingles vaccine ... Another steep challenge: distributing doses that must be kept very cold. Both the Moderna and Pfizer shots are frozen but at different temperatures. Moderna announced Monday that once thawed, its doses can last longer in a refrigerator than initially thought, up to 30 days. Pfizer’s shots require long-term storage at ultra-cold temperatures."

• Flu Shot May Shield You From Severe COVID - WebMD, 11/2/20 - "COVID patients who had not received a flu vaccine within the last year had 2.4 times greater odds of being hospitalized and 3.3 times greater chance of being transferred to the ICU ... Unfortunately, we do not know why the flu vaccine would have this beneficial side effect," he said. "Our study did not look at this specifically. [But] if one looks at the available scientific studies, we can guess that the flu vaccine might increase natural killer cell activity, a type of immune cell that has been shown to target cancer and cells infected by viruses ... The flu vaccine may also stimulate a patient's immune system to step up and fight off COVID-19 more quickly and rigorously than otherwise"

• A New Study Confirms Remdesivir's Effectiveness as a Coronavirus Treatment - Time, 10/8/20 - "In the final analysis, which included 1,062 people who were randomly assigned to receive IV remdesivir or a placebo for up to 10 days while in the hospital, the researchers provide more detailed data on how the drug affected metrics including how long people needed to be given supplemental oxygen or put on ventilators. All of the participants showed evidence of respiratory infection, mostly pneumonia, and 85% were considered to have severe disease, which meant that they had at least one of three symptoms: their blood oxygen levels were below 94% while breathing room air; they required supplemental oxygen; or they needed a ventilator to breathe. Among all the participants—both with severe COVID-19 and with more mild symptoms—those given remdesivir were able to be discharged from the hospital on average five days sooner than those receiving placebo."

• Can the common cold help protect you from COVID-19? - Science Daily, 9/29/20 - "The study, published in mBio, is the first to show that the COVID-19-causing virus, SARS-CoV-2, induces memory B cells, long-lived immune cells that detect pathogens, create antibodies to destroy them and remember them for the future. The next time that pathogen tries to enter the body, those memory B cells can hop into action even faster to clear the infection before it starts ... Because memory B cells can survive for decades, they could protect COVID-19 survivors from subsequent infections for a long time ... The study is also the first to report cross-reactivity of memory B cells -- meaning B cells that once attacked cold-causing coronaviruses appeared to also recognize SARS-CoV-2. Study authors believe this could mean that anyone who has been infected by a common coronavirus -- which is nearly everyone -- may have some degree of pre-existing immunity to COVID-19"
• Statins reduce COVID-19 severity, likely by removing cholesterol that virus uses to infect - Science Daily, 9/23/20 - "In short, removing cholesterol from cell membranes prevents the coronavirus from getting in ... statin use prior to hospital admission for COVID-19 was associated with a more than 50 percent reduction in risk of developing severe COVID-19, compared to those with COVID-19 but not taking statins. Patients with COVID-19 who were taking statins prior to hospitalization also recovered faster than those not taking the cholesterol-lowering medication ... statins are likely beneficial in preventing or reducing the severity of SARS-CoV-2 infection because, while intended to remove cholesterol from blood vessels, they are also removing cholesterol from cell membranes. As a result, the coronavirus can't get in"

The combined sample group from all seven studies included 1,703 severely ill patients, 678 of whom were administered steroids and 1,025 who received ordinary care (which did not include steroids) or a placebo. All of the patients were hospitalized and most were on ventilators. Over the course of 28 days, the death rate was 34% lower among the steroid-treated patients than among those in the control group ...

• Gut microbes could unlock the secret to healthy aging - Science Daily, 8/27/20 - "Bacteria and other microorganisms in the digestive tract are linked with dozens of health conditions including high blood pressure, high blood lipids, and body mass index (BMI) according to research presented today at ESC Congress 2020 ... The researchers found that higher levels of eleven bacteria (estimated from genetic data) were associated with a total of 28 health and disease outcomes. These included chronic obstructive pulmonary disease (COPD), atopy (a genetic tendency to develop allergic diseases like asthma and eczema), frequency of alcohol intake, high blood pressure, high blood lipids, and BMI ... To take one example, higher levels of the genus Ruminococcus were linked with increased risk of high blood pressure ... Regarding alcohol consumption, Dr. Groot said: "What we eat and drink is connected to microbiome content, so we studied the links with meat, caffeine, and alcohol. We observed a relationship between raised levels of Methanobacterium and drinking alcohol more often. It is important to stress that this is an association, not a causal relation, and more research is needed.""
• COVID-19 Is Transmitted Through Aerosols. We Have Enough Evidence, Now It Is Time to Act - Time, 8/25/20 - "The evidence in favor of aerosols is stronger than that for any other pathway, and officials need to be more aggressive in expressing this reality if we want to get the pandemic under control ... There are three possible ways the virus is transmitted, of which two have been emphasized by the WHO and the CDC. The first is through “fomites,” objects that are contaminated with the virus (which could include someone else’s skin). Early in the pandemic, concern over fomite transmission drove some people to bleach groceries and packages. The CDC now says fomites are a possible means of transmission, but likely not one that is major. For example, an intensive handwashing program in the UK led to only a 16% reduction in transmission. Significantly, other viruses that, like SARS-CoV-2 (the one that causes COVID-19), have a lipid envelope, do not survive long on human hands. That means someone would need to touch their eyes, nostrils, or mouth a short time after touching a contaminated surface in order to contract the novel coronavirus ... The second possibility for how COVID-19 spreads is through droplets, small bits of saliva or respiratory fluid that infected individuals expel when they cough, sneeze, or talk. Droplets—which the WHO and CDC maintain is the primary means of transmission of COVID-19—are propelled through the air, but fall to the ground after traveling 3-6 feet. However, published research, which has been replicated, shows that droplets are only important when coughing and sneezing. But when it comes to talking in close proximity, which appears to play a major role in COVID-19 transmission, droplets are less important than the third potential pathway: aerosols. Many diseases, including COVID-19, infect most effectively at close proximity. Since droplets are visible and fall to the ground between 3-6 feet, we can readily see and understand this route of infection. In fact, it was thought for decades that tuberculosis was transmitted by droplets and fomites, based on ease of infection at close proximity, but research eventually proved that tuberculosis can only be transmitted through aerosols. I believe that we have been making a similar mistake for COVID-19 ... “Aerosol” (sometimes referred to as “airborne”) transmission is similar to droplet transmission, except that the bits of fluid are so small that they can linger in the air for minutes to hours"

• Sweden's COVID Policy Didn't Create Herd Immunity - WebMD, 8/13/20 - "Diverging from much of the world, Sweden let COVID-19 spread in hopes the population would develop "herd immunity." But the risky strategy failed ... Authorities predicted that 40% of the people in Stockholm would get the disease and develop protective antibodies by May. The actual prevalence, however, was around 15% ... It is clear that not only are the rates of viral infection, hospitalization and mortality [per million population] much higher than those seen in neighboring Scandinavian countries, but also that the time-course of the epidemic in Sweden is different, with continued persistence of higher infection and mortality well beyond the few critical weeks period seen in Denmark, Finland and Norway ... antibodies are much less common in only mildly ill or asymptomatic patients. This means they are likely not immune, and can't prevent the spread of the virus, the study noted. This is central to the concept of herd immunity"
• These are the top coronavirus vaccines to watch - Washington Post, 8/13/20 - "RNA vaccines contain a strip of genetic material within a fat bubble. Once inside the cell, the RNA generates a protein found on the surface of the virus. The immune system, presented with the protein, learns to recognize the virus ... These vaccines have the advantage of speed — they can be quickly designed and manufactured. But they have never been approved for use outside of medical research and will likely require two doses ... Viral-vectored vaccines can be designed quickly. One concern is that people can develop immunity to the viral vector, making this approach potentially less useful if booster shots need to be given ... In a more old-fashioned approach, the virus is weakened so that it does not cause disease, but still triggers the immune system’s defenses. The vaccine for measles, mumps and rubella uses this approach ... Inactivated virus vaccines contain dead virus, incapable of infecting people but still able to instruct the immune system how to mount a defensive reaction against an infection. The polio vaccine invented by Jonas Salk used this approach, and flu vaccines use this technology ... These vaccines typically take longer to manufacture."
• Face masks with valves or vents do not prevent spread of the coronavirus, CDC says - Washington Post, 8/13/20 - "The purpose of masks is to keep respiratory droplets from reaching others to aid with source control,” the agency’s guidance reads. “However, masks with one-way valves or vents allow air to be exhaled through a hole in the material, which can result in expelled respiratory droplets that can reach others. This type of mask does not prevent the person wearing the mask from transmitting COVID-19 to others."

This could help explain why some people show milder symptoms of disease while others get severely sick ... 40 to 60 percent of people never exposed to SARS-CoV-2 had T cells that reacted to the virus. Their immune systems recognized fragments of the virus it had never seen before ... fighting off a common cold coronavirus can indeed teach the T cell compartment to recognize some parts of SARS-CoV-2 and provides evidence for the hypothesis that common cold viruses can, in fact, induce cross-reactive T cell memory against SARS-CoV-2 ... this study provides very strong direct molecular evidence that memory T cells can 'see' sequences that are very similar between common cold coronaviruses and SARS-CoV-2" - Note:  I've been saying this for years and as recent as my last newsletter, getting the flu vaccine every year likely makes you particularly immune from similar viruses in the future.

Scientists Are Skeptical - NYT, 7/29/20 - "Now a study suggests that people who have received certain routine vaccines in the recent past — including childhood vaccinations like measles-mumps-rubella and polio, as well as adult flu vaccines — have lower coronavirus infection rates than those not recently vaccinated"
• Another Effect of COVID: Lasting Hearing Problems? - WebMD, 7/31/20 - "120 U.K. patients who had been hospitalized for COVID-19 took part in a phone survey ... When the patients were asked if they had any changes in their hearing, 13% said it was worse. Eight patients said their hearing had deteriorated and eight said they had tinnitus (ringing in the ears)"
• Hydroxychloroquine No COVID Cure, Experts Warn - WebMD, 7/29/20 - "Former FDA Commissioner Scott Gottlieb, MD, said the verdict on hydroxychloroquine is not in doubt ... "We all hoped it was going to work. ... All of the studies that were rigorously done have pointed in the same direction, which is that the drug doesn't work," Gottlieb told MSNBC. "I think at this point, we can definitively say hydroxychloroquine doesn't work. I'm not sure what more we need to do.""
• Flu Drug Blocks Household Spread by 86% - Medscape, 7/9/20 - "Among placebo recipients, 13.6% developed the flu themselves. But among those who took a baloxavir pill instead, only 1.9% fell ill"
• Study: Sterilize N95 Masks With a Microwave - WebMD, 7/9/20 - "The materials include water, a glass container, mesh, a rubber band, and a 1,100- or 1,150-watt microwave. The researchers filled the container with 60 milliliters of water, then secured the mesh material over the top of it with a rubber band. They then placed the N95 mask on the mesh and microwaved it for 3 minutes. This effectively killed all viruses, including coronavirus, they say"
• Expert: Face Masks Reduce Wearer's COVID Infection Risk by 65% - Medscape, 7/10/20 - "a "standard rectangular surgical mask ... will decrease the risk of infection to the person wearing the mask by about 65%" and that homemade masks also "should work quite well." - Note:  I've found the following to be the most comfortable plus they don't make your face itch.  I bought two 5-packs and keep them in the center console of the car.  Each day, I put the used one on the washing machine for the next wash.  My Maytag washer has a two hour allergen setting which I used for everything.
• Popular Heartburn Drugs Linked to Heightened COVID-19 Risk - Time, 7/7/20 - "respondents who said they used proton pump inhibitor (PPI) medications to treat their heartburn had anywhere from two to nearly four times the risk of testing positive for COVID-19, compared to people not using such medications. PPI drugs, which are available by prescription and over the counter, work by turning off the pumps in cells that release acid into the stomach. They can be taken once or twice a day; people taking PPI medications twice a day had a higher risk of infection compared to those taking them once a day."

• Here’s my pitch for getting the flu shot every year:

  • Does the Flu Provide Better Immunity Than a Flu Shot? - NYT, 10/28/16 - "just over half of patients infected with the 2009 H1N1 flu still had an antibody response after six months, while only about a third of vaccinated subjects did ... a 2008 study published in Nature found that survivors of the 1918 Spanish flu got lifelong immunity to that flu virus and, as it turned out, protection against the pandemic H1N1 flu in 2009"
  • There was a similar virus to covid-19 in 2003.  Click here for the video. I don���t know if the flu shot covered it but people obviously contracted it. I believe that’s why we're seeing some people contract covid-19 and experience almost no symptoms and other suffering an agonizing death. Maybe the ones with the lesser symptoms either got partial immunity from the 2003 flu shot or the actual disease itself.  True, the vaccine isn’t as effective as the disease itself but it does provide some protection which should cause the symptoms to be less severe.
• Coronavirus vs. Every 2000s Epidemic (March 19 update) Fatality comparison - YouTube video that graphs the coronavirus vs. previous pandemics starting from day 1, then ranks them on the right of the screen.  See how fast Covid-19 moves up to the top on the ranking.
• Hydroxychloroquine for COVID-19: What's the Evidence? - Medscape, 3/25/20 - "Three patients were transferred to the ICU, one died, and the other two stopped their treatment. By the way, none of the patients in the control group died or went to the ICU. Had these six patients not been dropped, the story we might have is that hydroxychloroquine increases the rate of death and ICU transfer in COVID-19 .... Before reading this study, I was 50/50 on hydroxychloroquine. After? ... Yeah, I'm right where I started. Because of the problems with the study design—not just its observational nature but that differential loss to follow-up—the data from the French study don't move the needle for me at all"
• FDA Approved Drugs Show Promise Against COVID-19 - WebMD, 3/24/20 - "The results showed that the most promising drugs included several antiviral drugs -- including Darunavir, Nelfinavir, and Saquinavir -- and several other types of drugs, including: the ACE inhibitor Moexipril; the chemotherapy drugs Daunorubicin and Mitoxantrone; the painkiller Metamizole; the antihistamine Bepotastine; and the antimalarial drug Atovaquone ... Another promising candidate is the cholesterol-lowering statin rosuvastatin, which is sold under the brand name Crestor ... Also on the list were certain antibiotics; metformin, the go-to drug for type 2 diabetes; the schizophrenia drug haloperidol; and the malaria drug chloroquine"
• COVID-19: Could Hydroxychloroquine Really Be the Answer? - WebMD, 3/18/20 - "Chloroquine was ruled out due to the risk of interactions with other medications for common comorbidities in infected patients, and because of possible adverse effects in patients undergoing resuscitation"
• Blood Type May Affect COVID-19 Risk: Study - WebMD, 3/20/20 - "those with A blood types had a significantly higher risk of COVID-19 while those with O blood types had a significantly lower risk"
• San Diego flu cases up, but severity and deaths are down - CBS8, 1/13/20 - "See the video.  This doc sees Tamiflu the same as I do. You have to start Tamiflu as early as possible and it stops the flu in its tracks. The studies claim that the average flu is only 5 days and Tamiflu only cuts it down by a day. That doesn't sound accurate. When I get the flu, it's more like three weeks and Tamiflu cuts it down to three days and those three days aren't as severe. You can get the generic in Tijuana for about $16.  Also inhousepharmacy.vu.
• Why do healthy children die from the flu? Study offers new insights - Science Daily, 2/15/18 - "We found that in young healthy mice the immune system overreacted to the influenza virus, which led to more inflammation, greater lung damage and increased mortality compared to healthy adults exposed to the virus"
• Repeated influenza vaccination helps prevent severe flu in older adults - Science Daily, 1/8/18 - "Repeated vaccination for influenza was highly effective in preventing severe and fatal infection caused by influenza in older adult ... The prevention of severe and fatal infection caused by influenza was observed mainly in patients who were vaccinated in both the current and previous seasons, which reinforces the recommendation of annual vaccination for influenza in older adults"
• Does the Flu Provide Better Immunity Than a Flu Shot? - NYT, 10/28/16 - "When a flu virus enters your body, the immune system fights the infection by producing a robust antibody response that can spring into action if the same strain of the virus returns. That protection can in some cases last a lifetime. “The evidence we have is that people who were infected back in the ‘30s still have immunity to those viruses,” says Dr. Alicia Fry, a medical epidemiologist at the Centers for Disease Control and Prevention ... Studies also show that even when the antibody response wanes, immunity from a natural infection tends to last longer than that from a vaccine ... For perspective, a 2008 study published in Nature found that survivors of the 1918 Spanish flu got lifelong immunity to that flu virus and, as it turned out, protection against the pandemic H1N1 flu in 2009"
• Totality of trials data confirm Tamiflu reduces length of symptoms, complications, and hospital admissions from influenza - Science Daily, 1/30/15 - "oseltamivir significantly reduces the risk of influenza complications requiring antibiotics (such as pneumonia) and hospitalisations in adults infected with influenza ... treating adults with laboratory-confirmed influenza with oseltamivir reduced the duration of symptoms by 21% compared with placebo (from 123 hours to 98 hours) ... oseltamivir reduced the risk of lower respiratory tract infections requiring antibiotics more than 48 hours after study entry by 44% compared with placebo (4.9% vs 8.7%), and hospital admission for any cause by 63% (0.6% vs 1.7%) in adults with laboratory-confirmed influenza"
• Are you crazy for working out while sick? - CNN.com, 12/22/14 - "If you don't have a fever, a runny nose is no reason to skip a workout ... If you are mildly sick, [staying] active will promote your immune function, and help you sleep better ... When you have a cold, you're typically contagious for about five full days, and your germs spread most easily during your two to three most symptomatic days ... Working out with a fever can make your health way worse ... Angarone recommends resting until your fever has been gone for a full 24 hours, without the help of any fever-reducing medications like ibuprofen"
• Effectiveness of Influenza Vaccinations in Singapore - Medscape, 11/5/14 - "vaccine effectiveness (VE) ... The crude estimates for the VE of the triavalent vaccine against both influenza A(H1N1)pdm09 and influenza B were 84% (95% CI 78–88%, 79–86%, respectively). Vaccine efficacy against influenza A(H3N2) was markedly lower (VE 33%, 95% CI −4% to 57%). An estimated 70% (RR = 0.30; 95% CI 0.11–0.84), 39% (RR = 0.61;0.25–1.43) and 75% (RR = 0.25; 95% CI 0.11–0.50) reduction in the risk of influenza A(H1N1)pdm09, influenza A(H3N2) and influenza B infections, respectively, in the recruit camp during the post-vaccination period compared with during the pre-vaccination period was observed"
• High-Dose Flu Vaccine in Older Adults: Worth It? - Medscape, 10/7/14 - "Those receiving high-dose vaccine had significantly higher antibody response to the vaccine. They also looked at who got sick. Overall, 228 persons receiving the high-dose vaccine and 301 receiving standard-dose trivalent vaccine had laboratory-confirmed flu, which translates into a relative efficacy of 24.2% ... The conclusions? In seniors 65 years or older, those receiving high-dose trivalent flu vaccine had better antibody response and better protection against getting sick with flu as compared to those receiving standard trivalent vaccine"
• Flu Hits Unvaccinated Hardest, Study Finds - WebMD, 2/14/14 - "even if the flu vaccine doesn't completely prevent you from getting the flu, it does offer "a protective effect against severe disease." ... Flu kills around 35,000 people a year, and about 200,000 a year end up in the hospital"
• High-Dose Flu Vaccine: The Evidence Is In - Medscape, 1/3/14 - "The results: case closed. The high-dose shot was more effective in seniors. It was 24% better at preventing flu than the standard flu shot"
• Ibuprofen no good in treating colds or sore throats - Science Daily, 11/4/13 - "compared with paracetamol, ibuprofen or a combination of both ibuprofen and paracetamol provide no advantage for patients overall with respiratory tract infections (otherwise known as colds or sore throats) ... steam inhalation, another common treatment method, has no clear benefit and around 2 per cent of people get mild scalding but not bad enough to see a doctor ... The research also showed that patients were more likely to come back within a month with worsening symptoms or new symptoms if they were prescribed with ibuprofen or ibuprofen with paracetamol"
• Flu shot may cut risk of heart problems, analysis finds - NBC News.com, 10/22/13 - "of the 6,700 patients, half got the flu vaccine and half the placebo or standard care, only a third of patients had a history of heart disease. But among those who got the flu shot, we saw a 36 percent lower risk of a major cardiac event"
• Higher Indoor Humidity Levels Might Slow Flu's Spread - WebMD, 2/28/13 - "the team found that when humidity levels were set to 43 percent, only 14 percent of the virus particles that were released were able to transmit the influenza virus, compared with a transmission rate of 70 percent to 77 percent in a relatively low-humidity environment (23 percent)" - Note:  That might be true but most of what I've read indicates that the virus is usually spread by surface to surface contact.  People touch something that has the virus then they touch their mouth, eyes or nose.
• At what point after a cold are you no longer contagious? - askville.amazon.com - "Cold symptoms settle in between one and four days after you are infected by a cold virus and typically last for about three days. At that point the worst is over, but you may feel congested for a week or more. During the first three days that you have symptoms, you are contagious"
• Cold or Flu: How to Tell - ABC News, 12/5/12 - See the table.
• Why is the flu more common during the winter season? - Science Daily, 12/4/12 - "The researchers found humidity could explain the seasonality of influenza by controlling the ability of viruses to remain infectious while they are in droplets or aerosols. The viruses survived best at low humidity, such as those found indoors in the winter, and at extremely high humidity. Humidity affects the composition of the fluid, namely the concentrations of salts and proteins in respiratory droplets, and this affects the survival rates of the flu virus" - Note:  If that's true a humidifier might help solve the problem but I believe the cause is cold weather decreasing your immunity.  See humidifiers at Amazon.com.
• Flu may boost Alzheimer's risk, research suggests - MSNBC, 2/16/12 - "Viruses such as influenza and herpes may leave brain cells vulnerable to degeneration later in life, and increase the risk of developing diseases such as Alzheimer's and Parkinson's, research suggests. That's because these the viruses can enter the brain and trigger an immune response — inflammation — which can damage brain cells"
• Giving flu shots to tots cuts ER visits by a third - MSNBC, 9/19/11 - "Recommending that all U.S. preschoolers get a flu shot cut visits to the emergency department for flu-like illness by more than a third, U.S. and Canadian researchers said on Monday in a study that showed the direct impact of vaccination policy changes on flu transmission"
• Antibiotics May Make Fighting Flu Harder - Science News, 3/14/11 - "Iwasaki and her colleagues treated mice for a month with four antibiotics commonly given to people with bacterial infections, then infected the rodents with the flu. Antibiotic treatment impaired the mice’s ability to make an important flu-fighting molecule called interleukin-1 beta or IL-1 beta, the researchers found. IL-1 beta is necessary to combat influenza and other viruses ... Gut bacteria are constantly priming the immune system to make IL-1 beta, keeping the immune system vigilant against the flu and other viruses ... Some Lactobacillus bacteria, on the other hand, are known as “friendly��� gut bacteria and may play a role in virus defense. Mice treated with an antibiotic called neomycin, which wipes out most types of Lactobacillus bacteria while leaving Sphingomonas bacteria alone, have a hard time fighting the flu" - Note:  It seems to be a common misconception of nearly everyone I know that if you've got a bad case of the flu you need to go to a doctor and get antibiotics when in reality, it probably slows recovery.
• H1N1 Swine Flu Deadly to the Young - WebMD, 10/20/09 - "In a normal flu season, 90% of deaths are in elderly people. Since September, 90% of deaths have been in people under age 65 -- with almost a quarter of the deaths in young people under age 25"
• Live Attenuated Flu Vaccine May Be Less Effective Than Inactivated Flu Vaccine - Medscape, 9/24/09 - "the inactivated influenza vaccine (injection) was more effective than the live attenuated vaccine (intranasal spray) in preventing laboratory-confirmed symptomatic influenza A (mostly H3N2) in healthy adults"
• Shots beat back the flu much better than spray - msnbc.com, 9/23/09 - "In a study of nearly 2,000 healthy adults during a recent flu season, standard shots were twice as effective against regular winter flu as the newer nasal spray" - Note:  For what it's worth, I read or viewed somewhere that the shot contains dead viruses and the spray contains weakened viruses.
• 2 Easiest Ways to Catch Swine Flu - WebMD, 9/18/09 - "Having a sick person cough directly into your face ... That gives you more than a 50% chance of getting sick ... Touching something contaminated with flu virus and then touching your nose, mouth, or eyes with your unwashed hand gives you a 31% chance at getting sick"
• Seniors may have immunity to swine flu - msnbc.com, 9/17/09 - "Researchers believe seniors have a partial immunity to swine flu because of exposure to similar viruses in their lifetimes. It is a rare bit of good news before the start of the regular flu season, which generally kills 36,000 people a year, most of them elderly"
• Swine Flu: How Long Are You Infectious? - WebMD, 9/15/09 - "On the eighth day after symptoms struck, 8% to 19% were still shedding live H1N1 virus ... The second study ... showed that 80% were still shedding virus after five days of illness, 40% at seven days, and 10% at 10 days"
• Vaccination Of 70 Percent Of US Population Could Control Swine Flu Pandemic - Science Daily, 9/10/09 - "An aggressive vaccination program that first targets children and ultimately reaches 70 percent of the U.S. population would mitigate pandemic influenza H1N1 that is expected this fall"
• Effect of Influenza Vaccination of Nursing Home Staff on Mortality of Residents: A Cluster-Randomized Trial - J Am Geriatr Soc. 2009 Aug 4 - "Influenza vaccine was administered to volunteer staff after a face-to-face interview ... Staff influenza vaccination rates were 69.9% in the vaccination arm versus 31.8% in the control arm. Primary unadjusted analysis did not show significantly lower mortality in residents in the vaccination arm (odds ratio=0.86, P=.08), although multivariate-adjusted analysis showed 20% lower mortality (P=.02), and a strong correlation was observed between staff vaccination coverage and all-cause mortality in residents (correlation coefficient=-0.42, P=.007). In the vaccination arm, significantly lower resident hospitalization rates were not observed, but ILI in residents was 31% lower (P=.007), and sick leave from work in staff was 42% lower" - Note:  I keep hearing people say it's not worth it to get the flu shot.  The way I look at it, the most likely cause of dying from the flu would be being exposed to a virus that is very different than what you've been exposed to in the past.  I feel that the more flu shots you've had in the past, the lower the chances of that happening.  I mentioned before about a virus that I got in Australia that I though would kill me but it's a good  example.  It's got nothing to do with flu shots but it was probably a virus that nearly killed me from neck cancer that may have been prevented by the HPV vaccine.  Something to think about for people foreign things like the flu shot.

But this liquid phase apparently isn’t tough enough to protect the virus against the elements, and so the virus loses its ability to spread from person to person"
