Because of the ridiculous politicization of COVID and the response to it I take NOTHING at face value since every time the "experts" make an assertion, those assertions change months (if not weeks) later. Just look at the ridiculous evolution of masking guidance. How the vaccine story evolved from you won't get it it to you won't spread it to well, maybe your symptoms won't be quite as severe to the real truth after the FDA and Pfizer were forced to provide the background documentation after getting sued that the vaccines are less than 20% effective. What a shock - big phrama that has already had to pay out billions in the past for lying was lying again?
