Perhaps you should spend some time understanding vaccines.

Not all vaccines can prevent infection and spread. The yearly flu shots don’t. Viruses evolve, some much more rapidly than others. So vaccination against a specific strain may prevent infection, mutations then wreck that.
It doesn’t help when people don’t get vaccinated becoming petri dishes for evolution.
