Side effects of the polio vaccine

A tender, red or slightly swollen injection site can occur as the immune system responds. Some people feel tired, irritable or mildly feverish for a short time. These reactions do not mean that the vaccine has caused polio.

The type of polio vaccine and the person's age, health and other vaccines given at the same visit can affect what is noticed. Tell the vaccinator about previous reactions, allergies, pregnancy or a weakened immune system before vaccination.

Keep the arm moving gently and use a cool, clean compress over soreness. Rest and drink fluids. If you need medicine for discomfort or fever, ask a pharmacist or clinician which option and dose are suitable for you or your child.

Stay for the observation period recommended by the vaccination service, particularly if you have had an allergic reaction before. Keep the vaccination record and tell future healthcare professionals about any significant reaction.

Call emergency services immediately for trouble breathing, swelling of the face or throat, widespread hives, collapse, or severe weakness soon after vaccination. These can be signs of a serious allergic reaction.

Contact a clinician if fever is persistent, the injection-site redness or swelling is rapidly spreading, or symptoms are severe or concerning. For routine vaccine planning, see [Childhood Immunisation](/treatments/preventive-care-and-vaccination/childhood-immunisation/).

Ask which polio vaccine you are receiving, what reactions are expected, and whether your medical history changes the schedule. Confirm how to report a reaction and when the next dose is due.
