That is not how any vaccine works. A vaccine decreases the chance of a catching a disease, it does not eliminate it.
The way the disease is eliminated is by getting as large a fraction as possible of people vaccinated, so that spread is stopped.
Surely this is not the first time you have heard of herd immunity?
No, a vaccine decreases the chances of developing a disease, but they rarely if ever decrease the chances of "catching it" (getting infected).

This didn't work as COVID mutated and the vaccine is not effective against the new strains anyway.. But once people will get infected with Omicron this will sort itself out: https://www.wsj.com/articles/herd-immunity-is-over-superimmu...
