I believe the polio vaxx actually gave 200,000 people polio
Reach your own conclusion, but the vaccine administered in the US and other advanced nations is injected. It used a ‘dead’ virus, and you CANNOT contract polio from it.
In developing countries it is still common to use an oral administration with a *live* virus element. Children *can* contract (rarely) polio from this oral vaccines.
Is it economics or eugeniucs? You make the call.
