You could confine yourself to your property if you have no faith in the ability of your injection to protect you from the virus that it supposedly protects you from.

If your vaccination can't protect you from a virus that another human being is harboring, why bother with it? Would you take a pain reliever that required your neighbor to take it as well for it to be effective for you?

The "community immunity" principle in operation:

When a critical portion of a community is immunized against a contagious disease, most members of the community are protected against that disease because there is little opportunity for an outbreak. Even those who are not eligible for certain vaccines -- such as infants, pregnant women, or immunocompromised individuals -- get some protection because the spread of contagious disease is contained. This is known as "community immunity."
