Try to think logically.
The vaccine either works or it doesn't.
You don't need other people to get vaccinated to protect you if it works.
FFS use your head kiddo.
We do need 80% of people to get vaccinated to protect
everyone, based on R0 factor, etc.
The vaccine works. It reduces viral load if infected and vaccinated. It reduces severe illness. If it reduces viral loads then it helps others, but works even better if everyone is vaccinated.
God, you are seriously falling behind here. Try to keep up. Maybe read my post three or four times?
