Childhood immunisation schedules and hesitancy
Also known as Vaccination schedule · NIP · Child immunisations · Vaccine hesitancy
GP-fellowship guide to childhood immunisation: the Australian NIP structure from birth hepatitis B through 2/4/6-month hexavalents to the 4-year booster, live vaccine timing rules including MMR at 12 months and post-immunoglobulin intervals, true versus false contraindications with egg-allergy MMR safety evidence, answering the MMR-autism myth with Taylor, Demicheli and Hviid data and refuting immune overload, cold-chain and IM-site administration by age, catch-up principles, preterm and Aboriginal special-group rules, febrile-seizure counselling numbers, No Jab No Pay evidence, and AIR record-keeping.

Red flags
- Anaphylaxis to a previous vaccine dose is a TRUE contraindication — everything else (mild illness, runny nose, family history of autism, egg allergy) is not
- Rotavirus has strict first-dose and last-dose age limits — a late presentation may miss the window entirely; check before booking catch-up
- Never delay a scheduled vaccine for a runny nose — deferral visits are how coverage dies one child at a time
- Infants of HBsAg-positive mothers need hepatitis B immunoglobulin AND vaccine within 24 hours of birth — missing this is an avoidable chronic infection
Overview
Childhood immunisation is general practice's highest-volume preventive intervention and its most common site of parental doubt. The Australian NIP is a timed architecture — birth, 2/4/6 months, 12 months, 18 months, 4 years — engineered around maternal antibody waning, live-virus rules, and combination vaccines that deliver six antigens in one needle. The GP's job is threefold: give the right vaccine at the right time, answer hesitancy with data instead of dismissal, and keep the record straight in AIR.[10]
