The Polio vaccine is still administered in the US as standard practice.

TB as well.

As a counter example TB and some meningitis vaccines have been dropped in many EU countries because of cost/benefit, as in not enough of a disease incidence to justify covering the cost of the vaccine.

You can still get them voluntarily but you have to pay from your own pocket.

>Various vaccines are no longer recommended because of the virtually nonexistent risk.

Such as?

smallpox

Smallpox has been eradicated, that's not even virtually nonexistent.

Only risk I see is biological warfare, but why do that with a virus we have a vaccine for?

There are multiple other scenarios where the virus could become released into the wild again: infection by clearing up old storage sites, a laboratory accident, or some terrorist spending 100k US$. And all of these have happened (although the latter was "just" horse pox).

The other type of polio vaccine is still recommended (and even mandatory in many countries) so there is nothing to be worried about if you take all the recommended vaccines.
