It does not prevent transmission or infection, per the pharmaceutical companies own admission

fucking no, stop lying.

Data from 43,448 participants, half of whom received BNT162b2 and half of whom received placebo, showed that the vaccine candidate was well tolerated and demonstrated 95% efficacy in preventing COVID-19 in those without prior infection 7 days or more after the second dose

in fact, it's even better than 95%, because

Among 36,523 participants who had no evidence of existing or prior SARS-CoV-2 infection by the time of the immunizations, there were 170 cases of COVID-19 observed with onset at least 7 days after the second dose; 8 cases occurred in vaccine recipients, and 162 in placebo recipients

only 8 of the vaccine group got covid. that's 8 in over 18000

the vaccine absolutely stops covid.

preventing transmission still needs more studies, but so far it's looking like they do reduce the transmission as well, obviously.

I bring up the bubonic plague to refute the absolutely retarded statement of "when has our immunity ever failed us". the author must have severe brain damage or a total ignorance of how the world works to make such a statement, which sheds doubt on the rest of his claims too.
