> No one ever said the original vax prevented against transmission.
CDC Director Rochelle Wolensky said: "Our data from the CDC today suggests that vaccinated people do not carry the virus, don't get sick, and that it's not just in the clinical trials, but it's also in real-world data."[1].President Biden said, “If you’re vaccinated, you’re not going to be hospitalized, you’re not going to be in the ICU unit and you’re not going to die.” He then went on to says: “You’re not going to get Covid if you have these vaccinations.”[2]
> This has always been a pandemic of the unvaccinated.
"Fifty-eight percent of coronavirus deaths in August were people who were vaccinated or boosted, according to an analysis conducted for The Health 202 by Cynthia Cox, vice president at the Kaiser Family Foundation.

Does vaccinating against Covid-19 prevent _some_ transmissions - yes, obviously. efficacy measures that percentage.
Does vaccinating against Covid-19 prevent _all_ transmissions - obviously not.
Watch out for the people conflating these two statements, rhetorically shifting from one the other when it suits them.
e.g. the (wrong) statement that "vaccinating against COVID-19 doesn't prevent transmission so it's useless" uses the (true) first sense for the first half, then draws a conclusion as though it's the second sense.
