> I have a hard time believing you somehow missed fauci or Walenski or ALL of the mainstream media going on for months about the vaccine preventing transmission I guess I did. Axios has been my primary news source, along with New York Times and The Guardian/Wapo once in a while. Most of the time I just Google my way to the information I'm looking for. I don't consume any TV based news, or Twitter based news or any other such social media news, appart for HackerNews. I also generally went directly to the CDC website, and didn't use retellings from other publications or press conference. By curiosity, I pulled up this archive from October 2020: https://web.archive.org/web/20201027130822/https://coronavirus.jhu.edu/vaccines/vaccines-faq https://web.archive.org/web/20201027130822/https://coronavir... John Hopkins FAQ on the vaccine at the time. It states: > Although the phase 3 clinical trials are designed to determine whether vaccinated individuals are protected against disease, it will also be important to understand whether vaccinated individuals are less likely to transmit the virus. This is likely but not ensured. So that's at least one expert source corroborating my impression. I can't remember where I landed when I would have looked this up in 2020, but John Hopkins is a likely place I might have found. > They had no science backing those claims While I don't know why I didn't get the impression any official expert source told me it would prevent transmission and you feel many of them did tell you it would. I do still feel I need to make a correction on what you're saying. There's definitely science backing up the idea that vaccines can reduce transmission. It's based on historically observed outcomes from prior vaccines for other diseases, as well as on transmission models around herd immunity. The idea that the mRna vaccines would for sure prevent transmission had no evidence, but there was scientific based prior for thinking it might at least reduce transmission, specifically of the exact strain it targets.
