Contraindications of OPV and adverse events

OPV is a very safe vaccine and there is no contraindication to prevent giving it. Serious adverse reactions to OPV are very rare: acute flaccid paralysis has been reported in approximately one child in every 1–10 million children who have been vaccinated with OPV.
