How does the polio vaccine work?
How does the mumps vaccine work?
How does the smallpox vaccine work?
How does the measles vaccine work?
Granted, these don't mutate,
However, we haven't achieved sterilizing immunity yet. Yes, that will require almost all of us to be vaccinated.
Vaccines can create two kinds of immunity — effective immunity or sterilizing immunity.
Sterilizing immunity is complete protection from a virus — no virus particles can get into any cell in the body, it cannot replicate, and transmission can be stopped.
"That's like the holy grail of vaccines," said Sarah Caddy, a clinical research fellow in viral immunology at Cambridge University. "But that is really hard to achieve. To stop any virus particles getting in is virtually impossible."
Effective immunity stops the virus from causing severe disease but does not stop you from being infected or transmitting the virus.
Still, there are many who believe that sterilizing immunity should remain the ultimate goal of vaccine development. They argue that, while the immune response from the Pfizer and Moderna vaccines appears strong, no one really knows for sure how long the response will last.

However, those bacterial infections are still present in the world and people / children can and do contract them.
Those are all viral infections.

Not only do YOU not think critically, but you don't know the difference between bacterial and viral infections.
You could write 10,000 words based on your own opinions but it won't change actual facts.
Do some more research.
