No they were touted as stopping transmission. There's plenty of evidence from all the usual talking heads (Fauci, Pfizer + Moderna CEOS etc).
This numpty got vaccinated with his second pfizer (and 6th jab in total) and caught Covid 15 days later. If the vaccine creates antibodies that don't help prevent you being infected even 15 days after innoculation - perhaps the vaccines don't help at all.
The reason we were wearing masks and socially isolating is because the risk from covid (including the OG strain) has ALWAYS been minuscule. Use your common sense for goodness sake, the reason the deaths are trending down is because the entire population has been repeatedly exposed to the virus and we've built up memory to it. That's how the immunse response to coronaviruses works.
