I think that you might have an unrealistic expectation on what these vaccines can and cannot do.
The current lot of vaccines.
DON'T prevent contraction of the virus.
DON'T prevent person to person spread.
But they DO lesson the severity of a virus infection. However considering that 80% of sub 60 year olds have either light or no symptoms, I do ask myself what it is we accomplish by vaccinating this demographic.
