If one was exposed (positive antibody test) or recovered from COVID, do they need vaccine right away?
So far, COVID clinical trials were designed for "approval" since asymptotic pts were not tested or followed.
People under 40s has almost zero chance to die. Do they need to be vaccinated? After all, durability of natural immune system or due to vaccination are unknown.
In my book, so far, the Covid response was a failure world-around.
