You post a lot of things as fact that are just not known and will eventually be known and probably proven incorrect. And a complete misconception of what vaccines do! You are correct in that vaccines do not prevent an individual from encountering the virus, or prevent the virus from entering your nose. But they are very effective at preventing the virus from successfully setting up camp, from establishing a beachhead. That prevents illness, that prevents a significant viral load, and with no viral load, there is very little likelihood of transmission to others.
Just about every other vaccine in history has prevented transmission of the disease to others. And early studies out of Israel would seem to indicate that this is the case with the vaccines used in Israel, primarily the Pfizer vaccine.
