Polio Vaccines

Oral, live-virus vaccine (OPV) can cause polio in vaccine recipients and contacts.  It has caused Guillain-Barre syndrome (GBS) in recipients.  It may also contain live monkey viruses that have been associated with human diseases.  The oral vaccine is no longer recommended in the U.S.

Killed polio vaccine (IPV) has also caused significant effects, including cancers from a contaminated vaccine, but is not known to cause polio in recipients.
