This is what I heard when the vaccines were first rolled out
If you are vaccinated you are much less likely to get infected with Covid
If you are vaccinated and do get infected with Covid you are much less likely to get seriously sick
If you are vaccinated and do get infected with Covid you are much less likely to infect someone else
If you are vaccinated and do get infected with Covid and you do infect someone else, they are much less likely to get seriously sick
What more do you want a vaccine to do?
