Infants and children aged <10 years who have not received polio-containing vaccine at the recommended schedule points may need extra doses of vaccine and/or an alternative schedule. Children who only need polio immunisation can receive inactivated poliovirus vaccine for catch-up.
IPV containing vaccine is funded through the NIP for all children <10 years who have missed a dose of polio-containing vaccine. For details see the National Immunisation Program Schedule.
See Catch-up vaccination for more details, including minimum intervals between doses.
