Teen Immunisation Schedules — What You Need to Know

What changes in adolescence

Immunisation in the teenage years builds on vaccines given in infancy and childhood. Protection from some infections reduces over time. Boosters are additional doses designed to strengthen and prolong immunity as your teen grows older.

Adolescence also brings new environments — high school, sport, part-time work, social events, travel — where close contact increases exposure to infectious diseases. Booster vaccines help maintain protection during this more socially active stage of life.

Why boosters matter

A booster dose reminds the immune system how to recognise and respond quickly to specific infections. Immunity does not always remain at the same level throughout adolescence.

In Australia, commonly scheduled adolescent vaccines include:

• dTpa (diphtheria, tetanus, pertussis) booster

• Human papillomavirus (HPV) vaccine

• Meningococcal ACWY

• In some jurisdictions, Meningococcal B

Boosters protect not only your teen, but also vulnerable members of the community, including infants, older adults, and people with weakened immune systems.

How school programs fit in

Many adolescent vaccines are delivered through school-based immunisation programs under the National Immunisation Program. School clinics improve access and uptake, yet missed doses still occur due to illness, absence, consent form delays, or changing schools.

A missed school session does not mean the opportunity is lost. Catch-up vaccination remains available through general practice, pharmacies (where eligible), or community clinics.

How to check your teen’s records

In Australia, the Australian Immunisation Register (AIR) records vaccines given across the country. You can access your teen’s Immunisation History Statement via:

• myGov

• Medicare online services

• The Medicare Express Plus app

This statement is commonly required for school enrolment, certain workplaces, sporting activities, and travel documentation.

What to do if something looks incomplete

Occasionally, records appear incomplete due to interstate moves, overseas vaccinations, or paper-based documentation not yet uploaded to AIR.

If you notice gaps, bring any written vaccination records to your GP or immunisation provider. They can update the register or determine whether catch-up doses are required.

Accurate documentation reduces confusion later, particularly when applying for university placements, healthcare roles, or travel visas.

Catch-up and additional vaccines

Free catch-up vaccines are available under the National Immunisation Program for eligible age groups. Your GP may also discuss:

• Annual influenza vaccination

• COVID-19 vaccination for specific medical risk groups

• Additional vaccines for travel or underlying health conditions

Decisions are individual and based on medical history, risk profile, and family preferences.

A calm, informed approach

Teen immunisation decisions work best when you understand what each vaccine targets and why timing matters. A brief discussion with your GP allows you to review your teen’s record, confirm what is due, and ensure documentation aligns with school and future plans.
