What should you know about polio disease vaccine?

Vaccination prepares immune defences before exposure to poliovirus. Protection is built through the schedule recommended for a person's age, previous doses, health, and local public-health guidance. Different polio vaccine formulations may be used in different programmes; a healthcare professional can explain which one is offered. Vaccination protects the person who receives it and makes it harder for virus to circulate among people who are vulnerable or cannot be vaccinated.

Review the child's vaccination record or your own record with a clinic. If doses were missed, ask about catch-up vaccination rather than restarting the schedule without advice. Tell the vaccinator about a serious previous reaction, immune-system problems, pregnancy, or significant current illness. Remain at the clinic for the observation period they recommend and keep the record updated. Childhood schedules and guidance are explained in Childhood Immunisation.

Mild soreness, tiredness, or a short-lived fever can occur after vaccination. Seek urgent help for trouble breathing, swelling of the face or throat, widespread hives, collapse, or another severe reaction soon after a dose. Contact the clinic if a reaction worries you, lasts longer than expected, or affects drinking, alertness, or normal activity.

Ask which doses are due, whether a catch-up plan is needed, which formulation is being offered, and how prior illness or immune conditions affect timing. Confirm what reactions are expected and who to contact if symptoms appear after vaccination.
