One of the copy-and-paste #antivax talking points is that #polio was caused by #DDT. For everyone repeating this vile lie:

My grandmother was a polio survivor. She caught the disease in childhood, before DDT was in use as a pesticide. When I was a small child, she could walk, sort of, with crutches. By the time I was in high school, she was wheelchair-bound, as she would be for the rest of her life.

Consider this an engraved, gold-plated, personally delivered invitation to go fuck yourselves.
