If you're vaccinated, how can anybody infect you with it?

How did you and a whole bunch of other people apparently hear "95% efficacy against severe disease" and somehow decide that meant "100% efficacy against infection"?

  They did loudly proclaim 100% efficacy against infection when vaccines were firstly introduced. Like many other such proclamations that turned out to be wildly incorrect. No surprise people learned to discredit all such claims and their sources.

    Then you surely can link such an announcement?

    No, they really didn't.

April, 2021: https://www.pfizer.com/news/press-release/press-release-detail/pfizer-and-biontech-confirm-high-efficacy-and-no-serious https://www.pfizer.com/news/press-release/press-release-deta... > Thirty-two cases of severe disease, as defined by the CDC, were observed in the placebo group versus none in the BNT162b2 vaccinated group, indicating that the vaccine was 100% efficacious in this analysis against severe disease by the CDC definition (95% CI, [88.0,100.0]). Twenty-one severe cases, as defined by the FDA, were observed in the placebo group versus one case in the BNT162b2 vaccinated group, indicating 95.3% efficacy by the FDA definition (95% CI, [71.0, 99.9]). They've been clear since the very beginning that vaccinated people could still get infected, and that efficacy was regarding severe disease.

      I stand corrected, the number I had in mind is indeed about 100% protection from death and severe disease [0]. That was back when people were potentially waiting for more effective vaccines.
