What should you know about live attenuated polio vaccine?

A live attenuated vaccine contains a weakened form of the virus. It stimulates immune protection through the route used for vaccination and may help reduce transmission. The exact product and schedule depend on the person's age, local programme and public-health advice.

A clinician considers immune health, pregnancy, allergies, previous doses and current illness before vaccination. Children may receive polio protection within a broader childhood immunisation plan, while travel or outbreak guidance can change the recommendation.

Bring the vaccination record and tell the clinician about immune problems, medicines that suppress immunity, allergies, pregnancy, recent illness or a previous reaction. Do not delay a scheduled dose without discussing the reason with the vaccination team.

Follow aftercare instructions and keep the record updated. Mild soreness, tiredness or fever may occur depending on the product. Wash hands carefully after toileting and follow any specific hygiene advice given for the vaccine used.

Seek urgent help for trouble breathing, swelling of the lips or throat, collapse, severe weakness or a seizure after vaccination. Obtain prompt medical assessment for new limb weakness, difficulty walking, swallowing or breathing, or severe illness, whether or not vaccination was recent.

Ask which polio vaccine is planned, why it is recommended, whether your health or medicines change the choice, and when further doses are due. Check what hygiene measures and warning symptoms apply to your household.
