There is a reason why it usually takes about ten years and not six months to develop and test a new vaccine. The current vaccines were not adequately tested for either safety or efficacy IMO. On efficacy, would these have been even approved for EUA if it was known that they would lose close to half of their efficacy in less than six months? Even now, there is no good information on how often boosters may be needed. Trudeau of Canada was boasting the other day that he was in negotiations to purchase up to sixty million doses of vaccines annually to cover the period up to 2024. That is two boosters a year. And yes you are absolutely right Jbog there is no long term data on safety. So why not make them mandatory for every man, woman, and child in America?
