Now, if you just add in some of this you will be doubly protected against the damn virus and also get any lice out of your shiny hair

They prefer a denser undergrowth than I can provide thankfully.

As far as Vitamin D, living in a more southern climate I have a daily prescription straight form God

That's why I need a D supplement. But then I don't worry about drought so much.

I have to say Selenium seems to go under the radar a bit.
And you have to take the industry studies with a large pinch of salt.

But...

In a now-famous 1996 study, 200 micrograms per day of L-selenomethionine was found to significantly protect patients from death by all cancers (a 50% reduction compared with controls), from developing any cancer (a 37% reduction), and specifically from developing lung, colorectal, and prostate cancers.25

And:-

An important approach in cancer prevention has been to focus on the BRCA1 gene, a tumor suppressor that prevents cells from turning cancerous by repairing damage to DNA strands.53,60,61 Mutations in the BRCA1 gene reduce its anticancer effect. In fact, women with such mutations have up to an 80% lifetime risk of developing breast cancer, and up to a 60% chance of developing ovarian cancer.62

Because of the high incidence of cancer associated with this gene mutation, many women who test positive for it elect to undergo a preventive mastectomy—one of the most well-known being Angelina Jolie.

Selenium appears to help repair DNA damage caused by mutations in the BRCA1 gene. This was demonstrated by a study published in Cancer Epidemiology, Biomarkers, & Prevention. For the study, women with mutations in the BRCA1 gene were supplemented with placebo or selenium after precautionary removal of their ovaries and adjacent tissues.53 Researchers found that levels of chemical markers for DNA damage fell markedly in selenium-supplemented women, while markers of successful DNA repair rose.53 These were exciting results because less DNA damage means lower risk for future cancers.

And topically:-

Aging is associated with increased susceptibility to infections and cancer, and declining immune function plays a major role in this vulnerability. This age-related reduction in immune system vigilance is called immunosenescence.64

Some studies suggest that selenium levels generally decline as we get older, and this may partly underlie immunosenescence.8,19,20

Selenium supplementation has been shown in preclinical research to enhance proliferation of cytotoxic precursor cells, which give rise to the crucial T immune cells that fight cancer and viruses within the body.8,65 Moreover, an intriguing study of healthy men found that selenium supplementation for one year led to increased expression of genes associated with natural killer cell and T-cell cytotoxicity.66

Selenium is also critical for the optimal function of neutrophils,67 which are normally the most abundant type of white blood cell.68 Neutrophils ingest invading microbes and destroy them using an intricate system that is in part regulated by selenium and selenoproteins.69,70 In fact, neutrophils from selenium-deficient animals have been shown to be less effective in killing microbes than those from animals with sufficient selenium intake.8,65

Not surprisingly, selenium supplementation may boost immune system function in aging individuals and confer protection against infections. In one study, elderly individuals who supplemented with selenium (along with zinc) were significantly less likely to develop an infection over a two-year period than those who took a placebo.71

Aside from buttressing immune defenses against infection,

selenium also appears able to keep certain viruses from mutating and becoming more pathogenic once they’re inside the body. One group of researchers showed that a normally benign strain of coxsackievirus becomes virulent and damages the heart when administered to selenium-deficient mice. It was determined that replication in the low-selenium environment allowed the virus to directly change its genome to become more pathogenic. When the viral strain was administered to mice with adequate selenium, its genome did not change and the animals remained free of heart damage

.

Similarly, a relatively mild strain of influenza caused severe lung inflammation when administered to selenium-deficient mice.74 Follow-up research found that the virus had mutated its genome to become more aggressive in the presence of low selenium levels.75
