he ship with the idea, that you vaccine to less likely infect others, has long passed?

You piqued my curiosity. Just came across this paper:

Authorized mRNA vaccines were highly effective among working-age adults in preventing SARS-CoV-2 infection when administered in real-world conditions, and the vaccines attenuated the viral RNA load, risk of febrile symptoms, and duration of illness among those who had breakthrough infection despite vaccination. (Funded by the National Center for Immunization and Respiratory Diseases and the Centers for Disease Control and Prevention.)

On transmission after vaccination... I might be already posted this before -

https://www.bmj.com/content/373/bmj.n1112

A total of 552 984 residential households with 2-10 people where there was at least one case were included. In households where the index case was not vaccinated before testing positive, the study found 96 898 secondary cases from 960 765 household contacts (10.1%).

Meanwhile, in households where the index case received the AstraZeneca vaccine 21 days or more before testing positive, 196 secondary cases were seen in 3424 contacts (5.72%). With the Pfizer vaccine (one dose 21 days or more before testing positive), 371 secondary cases were found in 5939 contacts (6.25%).
