Medical care is not healthcare. It's the diagnosis and treatment of disease by drugs that have become the leading cause of death due to adverse drug reactions, defined as "properly prescribed and administered."
Some people just react adversely, especially if taking some other drug at the time. Most diseases are the result of what we put in our mouth from birth when we were "normal" as 97% are. When we get a problem at 40, 50 or 60, we did it to ourselves, but the good news is that it's reversible if we are willing to make changes, like what we eat.
The British Medical Journal reported 568 healthcare workers who got covid had 73% less severity on a plant-based diet. https://nutrition.bmj.com/content/early/2021/05/18/bmjnph-2021-000272
With covid having less than 1% fatality to begin with, the last thing we should need is a shot that failed the animal studies because they died. https://pubmed.ncbi.nlm.nih.gov/32908214
