Thank you for bringing this up. It isn’t “anti-science” to ask these type of questions and expect answers.
Indeed, it has always been the job of the FDA to hold drug companies responsible for proving that their drugs do not harm. Guilty until proven innocent. Given the rushed approval, incredible profit motive, reluctance of the FDA to respond to FOIA requests and the strong pushback against those who ask questions I think some skepticism is warranted.
So far, the cost-benefit for those not in high risk groups (especially children) seems waaaaay off. Why vaccinate children that are at almost no risk of serious illness when we clearly do not have all the info on long term vax risks?
