“I’ve never heard or read that the vaccine prevents COVID.”
OK, read it here first:
Pfizer prevents 95% of COVID cases (and nearly 100% of COVID deaths) among those vaccinated.
That is what the formal Phase III trials proved, and massive studies in Israel confirmed.
Concerning the Israeli study see pg 19 in the appendix.

Believe the vaccine showed 95% effective, while doing nothing was 94% effective for those that remained unvaccinated.
Sorry, it’s pg 23, not 19 in appendix.
