"Rumors of the current oral polio vaccine having been intentionally contaminated with drugs to cause sterility and “viruses which are known to cause HIV and AIDS” led to local refusals to accept the vaccine in parts of Africa. It’s likely that these rumors are related to the original OPV/HIV accusations. Partially as a result of these refusals, polio flared back up in parts of Africa after vaccination had led to positive steps toward eradication."
