What should you know about oral polio?

Poliomyelitis is a viral infection that can affect the nervous system. The oral vaccine is given as drops and trains the immune system to recognise poliovirus. It can also reduce the amount of virus passed through the gut, which helps limit transmission in communities.

The vaccine is for prevention; it does not treat weakness, paralysis, or an active polio infection. Vaccination schedules can differ according to age, previous doses, local public-health guidance, and travel plans.

Check the person’s immunisation record with a qualified clinician or vaccination service. Tell them about previous vaccine reactions, immune-system problems, current illness, and medicines that may affect immunity. Follow the recommended schedule and keep the record updated after each dose.

After oral vaccination, mild short-lived symptoms can occur. Do not delay urgent care for a child or adult who develops new weakness or difficulty breathing. Ask the vaccination provider how to handle a missed dose rather than restarting a course yourself.

Seek emergency help for sudden weakness, loss of movement, trouble swallowing, or breathing difficulty. Contact a clinician promptly for a severe allergic reaction after vaccination, such as facial swelling, widespread hives, wheezing, or collapse. A vaccination provider can also assess persistent fever or a concerning change in an infant’s behaviour.

Ask which polio vaccine is recommended, whether any dose is due, how previous doses are recorded, and whether a health condition changes the plan. Ask what symptoms after vaccination are expected and where to get help outside clinic hours.
