Late summer/early fall is notorious for one of them: provocation polio.
Unlike paralysis of the legs, which usually stems from an actual intestinal infection, provocation polio is a local paralysis that starts at the site of the shot.
Important to realize—in most cases, the vaccines are not contaminated. A rogue virus not cleaned from the skin is the problem.
If the public realized the polio vaccine only protects against a small percentage of potential paralysis cases, they would realize the polio vaccine isn't the panacea they were promised.
