Not sure what you're referring to. I can't find where I used the the word "stop".
Overall vaccinated people don't get as sick and don't die as often. They place less of a load on tattered healthcare systems. When they are sick their viral load decreases faster and there is evidence that what they do pass on isn't as infectious, so they are less likely to infect others.
If the vaccine is so effective at preventing infection, why are countries recommending even mandating booster shots and why are some countries cancelling passports after 6 months if you’ve only had 2 shots?
I thought you just said in your previous posts that the vaccine doesn’t stop infection or transmission

What about the numerous studies that show efficacy going to pretty much zero after 6 months?
Read the "How well it works" section for each vaccine: https://www.yalemedicine.org/news/covid-19-vaccine-comparison
After six months the vaccines remain perhaps 75% effective against infection and somewhat more against severe illness.

So far it's only you saying that. What studies?
