What should you know about the first polio vaccination?

Poliovirus can spread before illness is recognised and can sometimes affect the nervous system, causing weakness or paralysis. The first dose introduces the vaccine target to the immune system so it can respond more effectively later. One dose is the beginning of a course rather than the whole schedule; follow-up doses are used to reinforce protection at recommended times.

Take the child’s immunisation record to the appointment and mention allergies, previous reactions, immune conditions or current medicines. Ask what type of polio vaccine is being offered and when the next dose is due. Mild injection-site soreness, tiredness or fever may follow. Offer comfort, fluids and usual care, and use medicine only when a healthcare professional advises it.

Call emergency services for breathing difficulty, swelling of the face or throat, collapse, or a child who is difficult to wake after vaccination. Seek prompt clinical advice for a persistent fever, marked weakness, or a reaction that is becoming more severe. Keep the vaccination date and product details available if medical review is needed.

Ask how the dose fits the child’s national schedule, what to do if a dose is delayed, and which post-vaccination symptoms are expected. Confirm where future doses will be recorded.
