I agree antibiotics should be used more sparingly but vaccines work in a completely different way. Viruses don't build resistance in reaction to vaccines.
In 200 years smallpox never grew resistant to its vaccine.
Viruses like Flus can mutate quickly into a new form that old vaccines don't work on, but even then a new vaccine can be created that's effective against the new strain.
