BULL CRAP! The only people who need a 3rd shot are possibly the immunocompromised. And then possibly only after an antibody check, IMHO.
The elderly may need a booster as well though unclear. i’m talking over 65 or older - sometimes an insufficient immune response is mounted secondary to age. With what we are seeing on the ground with misfit the unvaccinated needing hospitalization i don’t think anyone needs a booster at this point And kids do not need to be vaccinated either
