> Why is it that we have been able to eliminate things like Polio and Smallpox, yet there's doubt about COVID?
The vaccines for polio and smallpox are extremely effective (some polio vaccines are up to 100%) and pretty much everyone received them, for decades. Covid vaccines are likely somewhat less effective, and there's considerable hesitancy in some countries. The US will be lucky to get to 70%, at the moment, and France may be even worse, for instance.
