> Given that the vaccine doesn't work to stop transmissions,
Nothing is perfect, but vaccination reduces transmission significantly:
> Two studies from Israel, posted as preprints on 16 July, find that two doses of the [Pfizer] vaccine ... are 81% effective at preventing SARS-CoV-2 infections. And vaccinated people who do get infected are up to 78% less likely to spread the virus to household members than are unvaccinated people.
Important to note that both of these studies are on pre-Delta variant patient sets, so unlikely to represent current real world impact on transmission from vaccination. This [0] is the most recent I've seen, and it suggests the reduction in transmission against Delta is smaller and wanes rapidly, even with the mRNA vaccines.
