BOTH varieties of polio vaccine have their drawbacks. They both have similar effectiveness, but the Salk (dead virus) doesn’t stop the spread, and the Sabin (live virus) can – occasionally mutate BACK into the nasty type of polio.
My question, other than the extra expense, is – why not do BOTH? Do the Sabin with the younger infants, to get that protection both painlessly and at an early age, then, for the kids who haven’t been immunized, before the kid heads into preschool/kindergarten, add in the Salk vaccine, which doesn’t mutate.
Administer the Salk type into the populations at the border – both local natives who weren’t vaccinated, and ALL – child and adult – who arrive without having gone through normal procedures. And, for the local areas where there is a mysterious outbreak of polio, administer the Salk vaccine there to ALL – child and adult.
It should be voluntary, not mandatory. My guess is that the problem of polio uptick is almost exclusively among those who received the Sabin vaccine. The Salk vaccine is both stable and well-tested, and should NOT need a federal program to get it into the hands of the health departments.
While we are at it, do a full hold/health inspection of any wanting entrance. If they carry a disease we don’t want, whether Monkeypox, Covid, or other communicable disease, kick them back to the border they violated to get here.
Now, after the Covid immunization debacle, will there be resistant populations? Of course. And, those people have GOOD REASON for their suspicions. We should never have a vaccine that is mandatory for all, nor required to be able to work.
