Measles Vaccine Guide: Booster, Age & Australia Schedule

A quick check of your vaccination record can be surprisingly confusing — especially if you’re trying to figure out whether you’re protected against measles. With outbreaks occasionally making headlines and travel requirements shifting, this guide breaks down who needs the measles vaccine, when, and whether a booster might be necessary.

Two-dose effectiveness: 97% ·
Routine first dose age: 12-15 months ·
Year introduced in Australia: 1968 ·
Number of doses recommended: 2

Quick snapshot

Five key facts about the measles vaccine, drawn from the Australian schedule and clinical evidence.

Label	Value
Effectiveness	97% after two doses (NCIRS)

Does the measles vaccine last for life?

For most people, yes — two doses of the MMR vaccine are considered to provide lifelong protection against measles. The NCIRS states that if a person has received two doses at least four weeks apart, with the first given at 12 months or older, no further doses are ever required.

Why don’t people born before 1970 need the measles vaccine?

• In Australia, people born before 1966 (the cut-off used by NCIRS) are considered immune from widespread natural exposure — measles was nearly universal before vaccination (NCIRS).
• If you have documented laboratory-confirmed measles infection, you are also considered immune (NCIRS).

Can I get measles if I was vaccinated 50 years ago?

• If you had two doses, immunity persists for life — no evidence of widespread waning (NCIRS).
• If you had only one dose, especially from the single-dose era (before 1998 in Australia), some protection exists but the NCIRS recommends a second dose if you’re unsure of your record and were born after 1966.

What this means: Your birth year and dose history are the two strongest predictors of your immunity. A quick check with your GP can resolve the uncertainty.

At which age is the measles vaccine given?

The National Immunisation Program schedule lists the first measles-containing dose at 12 months (MMR) and the second at 18 months (combined MMRV, which includes varicella). Children who miss the 18-month dose can catch up at 4-6 years.

Can I get the measles vaccine at 9 months?

• Routine vaccination does not start before 12 months, but infants as young as 6 months can receive an early MMR dose if travelling to countries with ongoing measles outbreaks or as post-exposure prophylaxis (Australian Immunisation Handbook).
• That early dose does not count toward the routine two-dose series — it must be repeated at 12 months or later (RACGP NewsGP).

What is the measles vaccine age in Australia?

• First dose: 12 months (MMR)
• Second dose: 18 months (MMRV) or catch-up at 4 years (NIP schedule)
• Children who missed doses: Free catch-up is available under the NIP for any unvaccinated or partially vaccinated person under 20 years of age (NCIRS).

The pattern: The schedule is designed for early protection within the first two years. If you’re planning an overseas trip with a baby, talk to your GP about early travel vaccination and get the itinerary right.

What are the side effects of the measles vaccine?

The most common side effects of the MMR vaccine are mild and temporary. According to NCIRS, about one in ten children may develop a low-grade fever, a mild rash, or temporary joint pain (more common in adults). These symptoms usually appear 7–12 days after vaccination and last a few days. Serious side effects, such as a severe allergic reaction (anaphylaxis), are extremely rare — occurring in less than one per million doses (NCIRS).

Decades of global research have found no link between the MMR vaccine and autism. The original study suggesting a connection has been retracted and widely discredited (NCIRS).

The balance: The risk of vaccine side effects is extremely low compared to the potentially severe outcomes of measles infection.

Where can I get the measles vaccine and is it free?

In Australia, the MMR vaccine is free under the National Immunisation Program for eligible groups. That includes children on the routine schedule, anyone born after 1966 who hasn’t had two doses, and travellers at high risk (NIP schedule). You can get it at your GP clinic, community health centre, or some pharmacies. The Grampians Public Health Unit, for example, is running an enhanced program offering free MMR to adults aged 20–59 who lack two doses or are unsure of their status, through June 2026.

Is the measles vaccine free in Australia?

• Children: Yes — all routine doses are covered by the NIP (NIP schedule).
• Adults born after 1966: MMR is free if you need a catch-up dose — no Medicare surcharge applies (NCIRS).
• Where to go: Ask your GP, local public health unit, or use the NSW Health resource to find a free clinic near you.

What this means: In most cases cost is not a barrier. If you’re unvaccinated or unsure, the first appointment is the only step — the vaccine itself won’t cost you a cent.

When was the measles vaccine introduced in Australia?

The measles vaccine first became available in Australia in 1968, according to the NCIRS vaccination guide for providers. During the 1970s only a single dose was recommended. That changed in 1998, when Australia adopted a two-dose schedule — the same year the MMR (measles-mumps-rubella) combination vaccine replaced the single measles shot.

The implication: If you were vaccinated before 1998, you likely received only one dose. Even if you had one dose, catching up with a second is simple and recommended — especially if you were born after 1966.

The takeaway: Knowing the history of measles vaccination helps interpret your own risk based on your birth year.

Measles vaccine timeline

• 1963 – First measles vaccine licensed in the United States (NCIRS guide)
• 1968 – Measles vaccine introduced in Australia (NCIRS guide)
• 1970s – Single-dose schedule used across Australia
• 1998 – Two-dose schedule adopted in Australia (NCIRS guide)
• Present – Routine MMR vaccination continues; catch-up programs for adults

Expert perspectives

“Infants as young as 6 months can receive MMR vaccine for travel to highly endemic areas during outbreaks and as post-exposure prophylaxis.”

Australian Immunisation Handbook (Department of Health)

“All people born during or after 1966 are recommended 2 doses of a measles-containing vaccine, given after 12 months of age and at least 4 weeks apart.”

NCIRS (National Centre for Immunisation Research and Surveillance)

Summary: For Australian adults born after 1966 who are unsure of their vaccination history, the choice is clear: get two doses of MMR vaccine, available free under the National Immunisation Program, or risk losing the protection that most of the population relies on. Your birth year, not your memory, is the best guide — if you don’t have a record, a single GP appointment gives you the protection you need.
