What should you know about Sabin poliomyelitis vaccine?

Sabin vaccine is a live, weakened oral polio vaccine. It is given as drops rather than an injection. The vaccine exposes the immune system to a weakened form of poliovirus so it can build protection without causing the usual disease in most people. Polio can affect the nervous system and may lead to weakness or paralysis, which is why vaccination remains part of childhood immunisation programmes.

The correct product and schedule depend on age, previous doses, local programme guidance and health circumstances. Oral polio vaccination and injected polio vaccination may both be used in different programmes.

Bring the child’s vaccination record and tell the vaccinator about serious immune problems, medicines that suppress immunity, or a previous severe reaction to a vaccine. Ask which dose is due and whether any doses were missed. After the drops, follow the clinic’s feeding and observation instructions. Keep the record updated and return for the next scheduled dose rather than restarting a course without advice.

Contact a clinician if a child becomes unusually unwell after vaccination or if you are concerned about a reaction. Seek urgent help for trouble breathing, facial swelling, collapse, severe weakness or another rapidly developing serious symptom. A mild, short-lived change in appetite or behaviour can be discussed with the vaccination team if it persists.

Ask whether Sabin vaccine is recommended for this child, which doses are recorded, whether a missed dose needs catch-up, and whether an immune condition or medicine changes the plan.
