Covid-19 Immunity: Plan A or Plan B?

WAITING FOR A VACCINE???

According to Professor John Ioannidis, “We need to understand the exact mechanism that leads to severe outcomes and death. Is it the virus itself or the immune response to the virus that is doing more damage in different cases. If it’s the virus and not enough immune response then we need to have a vaccine. If the problem is the over reaction of the immune system that eventually leads accidentally to destroying our own cells like lung cells, then a vaccine may actually be a bad idea.” He said there were attempts to make animal corona vaccines that failed because they over-stimulated the immune system.
What he describes is not new. Many deaths are caused by immune reactions gone haywire. “Cytokine storms” is an expression for one kind. There is some opinion, perhaps contested, that Covid deaths ARE from a haywire immune response. If so, some say it does not bode well for those who think a vaccine is the be all and end all.
Others emphatically believe this is NOT a problem, because the vaccine is only a small amount that quickly disappears.

The best part of Medscape are the comments buried below the articles:

“Frankly I do not believe there will ever be a successful vaccine as the virus modifies into a specific virus for a specific host. The only efficient treatment and solution is reactivation of adaptive immunity.”
“The problem in immunology is that antibodies are easy to measure while cellular responses are not. I’m an immunologist and I’m surprised how little MDs know or remember about immunology. My bold prediction is that antibody responses will never be protective for many viruses. Covid can infect cell to cell without exposing itself to antibodies in the blood. The immune response is “steered” by T Helper cells which have two subsets, 1 and 2. TH1 cells promote cellular immunity and Th2 cells promote a humoral response. They are counter regulatory. Any vaccine promoting a Th2 antibody response actually suppresses protective TH1 immunity. The age difference seen in covid is due to immuno-senescence or the shift from TH1 bias as children to Th2 bias as we age. The mortality rate of covid-19 vs. age correlates exactly with this.”

In a Medscape article, “experts interviewed say…the day a Covid-19 vaccine is widely available will not come this year and may not come by the end of 2021.” “the fastest time for developing a vaccine to date is 4 years, for the mumps vaccine.” Elsewhere, there was dismay about the short life of naturally formed antibodies. If they disappear rapidly so probably would those created in response to a vaccine.

Should we worry about the research?
Experimental vaccine volunteers in one article were 19 to 55, young and healthy. How helpful is that? The only people affected by Covid with any statistically relevance are quite old. A recent article in Nature and précised in the BMJ said that young people under 20 are only about half as susceptible to Covid as those over 65. And if they do catch the virus, more often than not, they have few or no symptoms. So if the vaccine is tested on young healthy volunteers, it will appear to be resounding success!
But does that have any relevance to its value to the elderly? How do we know it will not increase immune system over-reaction. However, another said that in the last phase of investigation, a hypothetical vaccine would be tried on older volunteers.

There is still no HIV vaccine and no vaccine for the first SARs. When SARs began to fade away, funding for vaccine research was cut. A cynic could see a profit motive in keeping Covid fear going for as long as possible.

One priceless comment (about censorship) found on Medscape is from Dr. Kurt Kirkpatrick (May 23, 2020)
‘One thing I noticed is the rapid adoption of the “vaccine as a cure” vs. natural immunity for a disease that is 99% survivable. That should be a clue what is driving this mayhem.’

It does not sound like a vaccine should be relied on.

What Are My Odds???

The CDC report includes a fatality rate of only 0.2% to 0.05% risk for those under 65 and a 1.3% rate for those over 65. A hastily developed vaccine will presumably have some risk, which, given past snags. Why would any sensible person with a 99.8% probability of surviving from Covid-19 have any interest in taking it? Should it be forced on senior citizens?

COVID-19 IMMUNITY—PLAN A. (Vaccines are so Plan B minus)

Tuberculosis (no relation to Covid-19) was soon discovered to be an opportunistic disease concentrated among those with poor nutrition, with low levels of vitamin A and D. Were TB discovered today, we would still be waiting for the boffins to sequence the genome. Try searching Pubmed, ScienceDirect, Google Scholar or whatever you trust for “vitamin A AND vitamin D AND respiratory disease. (Or don’t, because most of it is below.) It is very surprising what research never reaches medical school. We are all expected to believe there’s nothing we can do except wait for the experts to provide a vaccine. Word has it that a no successful vaccine for a corona virus has been made before.
Miracles happen. England and Scotland are going to investigate vitamin D for possible benefit in Covid-19. One might think that Canada, also with a public health care system not looking for profit, might follow suit. If readers are outraged by the amount of material on nutrition and immunity that is being ignored…they should be.

A SUMMARY OF THE VERY LONG LIST OF ARTICLES ON VITAMIN A and D.
Vitamin A (retinol) has a long history of benefit in reducing the incidence of respiratory infection (viral or bacterial) and in treating same. Vitamin A and D are synergistic. The toxicity of large doses of one will be reduced by the presence of the other. (This fad for taking only vitamin D in large doses may end badly.) Vitamin D also has many articles citing its benefit in warding off respiratory infection. Vitamin D needs magnesium to work, as Aileen Burford-Maison, PhD and author of excellent books, frequently reminds us.

It is clear from the articles below and ones to be added that the balance between vitamin A and D is crucial and that contradictory results in some studies that use only one of them are the result of not fully understanding this.

Utilization of vitamin A requires zinc. Zinc also reduces its toxicity. Some vitamin A can be made by the body from beta carotene. (Interestingly, the popular hydroxychloroquine also needs zinc to work.)

Vaccine makers are trying to put vitamin A in the flu vaccine. This is just wrong in so many ways, especially since one research group credits the vitamin’s good effect on the immune system to its ability to change the microbiome. I.e., it should be consumed, not injected. This is all part of the controversy about adjuvants, like squalene. This is Whole Other Story and there are better sources than here.
One vaccine in veterinary medicine did not work unless the calf had vitamin A, so by all means, eat it.
If you do not believe all this, then you must read the long list of articles below.

DOSING and Toxicity
This information is not in the citations below. This website is not infallible. You have been warned.
There is not a lot on dosage. Multiple vitamins used to have 10,000 IU of vitamin A. Then in an abundance of caution, it was cut back to 5,000 IU. Now some multis have only half that. This change may have arisen at the time Accutane, a useless expensive vitamin A derivative, and also vitamin A mega doses became popular for acne. Taken during pregnancies, both caused birth defects (as does zinc deficiency).

Vitamin A capsules are available in 10,000 and fortified halibut liver oil capsules have 10,000 vit A (3,025 mcg RAE & 400 IU vit D (10 mcg). This is probably not a good ratio. Unfortified halibut liver oil (5,000/400) would be better. It is rare. Vitamin A RDA is 3,000 for men, & 2,300 for women with an upper limit of 10,000. (Except in pregnancy, the upper limit, in the case of illness, may be worth re-examining, considering the much higher doses used to treat measles.) Vitamin D RDA is 600IU to 800IU. RDAs are almost always wrong, according to some. Doctors who specialize in vitamin D will recommend far more.
The most concentrated source of vitamin A is liver. One ounce of chicken liver has 6,576 IU, beef liver, 9,985 IU. I.e., a 4 oz serving of liver will be well over the limit. While a hungry hunter once died from eating an entire seal liver, those who routinely eat small amounts of liver are probably healthier than most. Organ meats have far more nutrients than muscle meat.
Cod liver oil has both vitamin A and D, albeit not nearly so much as the less refined oils of old. The fancy fish oils claiming high levels of DHA and EPA, while beneficial, lack any significant A&D.
A can of sardines has 2% of vitamin A RDA and 110% of vitamin D RDA. (Sardines also have selenium, also good.)
Sun exposure, May to September makes a lot of vitamin D.
Vitamin A measurement units are gradually being changed from IU to RAE micrograms,
a.k.a. µg. This is an essay. Consumerlab.com explains it.

ON VITAMIN D AND RESPIRATORY DISEASE
This subject has as many or more articles as vitamin A. Consumer Lab says some papers found that adequate vitamin D was good, but too much was not. A small study of Covid patients, not large enough to be statistically significant, found that those who became sicker had lower levels of vitamin D. “Vitamin D is, as noted elsewhere, an immunomodulatory hormone which may help reduce respiratory infections, and is required in certain steps of the body’s immune response.”

[The addition of non-patentable supplements to a patented expensive vaccine is questionable, and if the other researchers are correct and the benefits are via vitamin A induced microbiome changes, the ploy is also unhelpful. Possibly Vitamin A is already added in the form of squalene (shark liver) to flu vaccines. However, many consider this adjuvant to be harmful, at least when injected. (It presumably would be nutritious if consumed orally.) Whether the benefits could be achieved more effectively and cheaply by oral supplements could be “profitable” research for non-profit research. Note that one of these articles says some vaccines do not work without vitamin A.]

Role of Fat-Soluble Vitamins A and D in the Pathogenesis of Influenza

Reduced exposure to solar radiation, leading to a deficiency of vitamin D and hence impaired innate immunity, has been suggested as a trigger for influenza viral replication and as an explanation of seasonal influenza. Although this hypothesis accounts for many unexplained facts about the epidemiology of influenza, gaps remain in understanding the pathogenesis and manifestations of the disease. Several observations suggest a role for vitamin A compounds (retinoids) in the disease. This paper presents a new model of the etiopathogenesis of influenza, suggesting that host resistance and susceptibility depend importantly on the ratio of vitamin D to vitamin A activity.

Controlled studies in the 1930’s found more robust results. Cod liver oil given to 1,561 adults reduced the incidence of respiratory infections by 30% and another showed 50% reduced incidence of colds. We attribute the better results in the older study to the much higher vitamin D content of cod liver oil in the 1930s [Another article, lost, confirmed that today’s cod liver oil has lower levels of vitamins.]

The amelioration of hypervitaminosis D in rats with vitamin A

The administration of large amounts of Vitamin A to hypervitaminotic D rats decreases the toxicity of this condition.
An interesting question raised by this investigation is whether the physiological or biochemical function of vitamin D is dependent on the tissue level of vitamin A or its metabolites. In these studies, it was noted that as the amount of vitamin A was increased in hypervitaminotic D animals, there were fewer pathologic changes, better weight gain and longer life span. Gross-Selbeck (16) in 1935 reported that large amounts of vitamin A concentrates decreased the lethal toxicity of massive amounts of vitamin D. Thoenes (17) in an interesting paper speculated that vitamin A was an essential factor for the action of vitamin D and that administration of large amounts of vitamin D created a “relative avitaminosis A.” This present study tends to support the concept that some of the damage of hypervitaminosis D may be in part due to a relative avitaminosis A. https://rupress.org/jem/article/115/1/147/2999/the-amelioration-of-hypervitaminosis-d-in-rats

Adequate vitamin D levels were associated with a lower risk of pneumonia in a study of men and women ages 53 to 73 in Finland Compared to adults with vitamin D levels above 20 ng/mL, the likelihood of being hospitalized with pneumonia was 40% higher among those with levels below 20 ng/mL but above 13.5 ng/mL, and 140% higher among those with levels below 13.5 ng/mL, after adjusting for other factors. The researchers found that a low vitamin D level was almost as strong a risk factor for pneumonia as smoking.

Based on the studies above, vitamin D appears to be most effective in reducing respiratory infections when patients do not already have adequate levels (20 ng/mL) of vitamin D and when vitamin D is given daily, not in extremely large periodic doses.
