They didn't say that at the beginning though did they
they WERE originally touted as a miracle cure.
the transmission reduction proven by statistics is a baseless argument and ridiculous.
Round and round we go!
In trials, effectiveness was ~95% - in some substudies effectiveness was 100%.
Once vaccines were rolled out, population level data allowed onward transmission to be studied (impossible to do in trials - one reason being the very high effectivness). In these datasets, vaccination substantially reduced both transmission (don't have COVID, can't pass it on) and onward transmission (vaccinated people with breakthrough infection less likely to transmit).
Unfortunately, these pretty amazing stats were quickly replaced with much lower figures, due to the rapid mutation of the virus & waning immnity post vaccination & infection.
These claims were not lies or untrue, they were based on the available evidence at the time.
