Vaccines and polio

Polio is a viral infection that can spread through close contact and contaminated food or water. In some people, the infection affects the nervous system and can cause muscle weakness or paralysis. Vaccination prepares immune defences before exposure, reducing the chance that poliovirus can multiply and spread. Some vaccines are given by mouth and others by injection, depending on the programme and the person’s circumstances. Completing the recommended schedule matters because protection is built through planned doses rather than a single conversation or visit.

Check the child’s or adult’s immunisation record with a healthcare professional and ask whether any dose is due or was missed. Tell the vaccinator about a previous serious reaction, immune problems, current illness, or medicines that affect immunity. Follow the local schedule and keep the record available when travelling or changing clinics. Mild soreness, tiredness, or a short-lived fever may follow some vaccines. Fluids and rest can help, while a pharmacist can advise on suitable symptom relief.

Get urgent help for sudden weakness, difficulty breathing, loss of consciousness, or a severe allergic reaction after vaccination. Arrange prompt assessment for new weakness in an arm or leg, difficulty swallowing, or breathing problems, whether or not vaccination is up to date. These symptoms need clinical evaluation and should not be explained away as a routine vaccine reaction. A clinician can assess exposure, neurological signs, and the need for testing or supportive care.

Ask which polio vaccine is used, whether the schedule is complete, how a missed dose is handled, and whether travel changes the plan. Ask what reaction is expected after the next dose and which symptom should trigger urgent help.
