People who were fully healthy, exercised daily, took their vitamins STILL caught this virus, and were f*cked up. So that take your vitamins/work out narrative is a lazy one. We've had professional athletes on record catch that & said it was a horrible experience.
Secondly, Pfizer, Moderna, Johnson & Johnson are not government agencies nor are they ran by the United States government.
*EDIT* The longer this virus hangs around, the more variants will be born, which could potentially lead to less effectiveness in the current set of vaccines.
