Ok so polio went down in India.
Not “went down”. E L I M I N A T E D. Immediately after full immunization was achieved. And despite the use of DDT. Therefore Suzanne Humphrey’s bizarre hypothesis is completely exploded.
But polio like illnesses have been on the rise .
So what? Those are not polio. The polio virus is not present in those cases. There are many diseases we do not yet understand, and have no vaccine for. In the normal course of events some of them rise in incidence, while some decline. There is no dramatic rise or decline in polio-like illnesses.
