yup, what i read is that in israel (where only bioNtek / pfizer has been used) everyone vaccinated is about 99% likely of NOT spreading it , but in the meantime pfizer CEO himself has admitted that (what they call) a booster shot will be needed 9 to 12 months after, which in essence comes down to a yearly vaccination. So if they cant reach over 24% in the states the effect on mass population is as good as nothing , unless they quarantine a zone for vaccinated people, make like stalin and move everyone behind a wall there.
