Given their YouTube push of vaccine marketing, this wasn't unexpected.
These are all getting removed. I assume this will as well. Of course Facebook announced today the same requirements just now. Not coordinated at all.
Proof of prior infection? Positive antibody test?
This would seem to be a scientific approach to the matter, given the studies illustrating T-cell and long-term bone marrow immunity in the previously infected. Why put anything in your body, even saline, if you don’t need it? There’s always some risk with any medical procedure.
Why is this even a thing when a vaccinated person can still spread a virus? It protects him or her from a severe case of
disease it does not prevent the spreading of the virus.
Vaccine reduces the spread.
Perhaps it's to reduce their liability (legal and PR)?
