They were lying. Or at the very least didn't understand the claims actually made by Pfizer/etc, which was only that these vaccines prevented the disease, not that they prevented infection/transmission. They made no claims about infection/transmission. We knew this in 2020: https://www.washington.edu/news/2020/12/02/covid-19-vaccines-may-not-prevent-spread-of-virus-so-mask-wearing-other-protections-still-critical/ https://www.washington.edu/news/2020/12/02/covid-19-vaccines... https://www.businessinsider.com/who-says-no-evidence-coronavirus-vaccine-prevent-transmissions-2020-12 https://www.businessinsider.com/who-says-no-evidence-coronav... https://www.fredhutch.org/en/news/center-news/2020/12/covid-19-vaccines-transmission.html https://www.fredhutch.org/en/news/center-news/2020/12/covid-... It comes down to the stupid conflation of SARS-CoV-2 and COVID-19 into just "covid". Pfizer/etc use the two terms correctly, saying they prevented COVID-19, but didn't say anything about stopping SARS-CoV-2, but because everyone thinks "covid" is the virus they can't seem to understand what was actually said.
