FDA experts have voted against approving Covid-19 vaccination boosters for anyone over the age of 16 in the USA, citing a lack of long term data and stating that the risks do not outweigh any benefits because the Covid-19 vaccines are killing at least 2 people for every 1 life saved.
Now just recently, FDA approves the booster (9/2021) with certain limitations. I’m sure we’ll see this change again. However the vaccine recipe hasn’t changed so we’re not entirely sure how this can affect the human body especially since we now know that it can cause blood clotting from the micro level to a larger level.
