What should you know about measles vaccine for adults?

Adults may need measles vaccination if they lack reliable immunity, have never completed recommended doses, or face increased exposure risk. A clinician can review your vaccination record, past illness, travel plans, work setting, and health conditions before advising whether MMR vaccination is appropriate. The measles, mumps and rubella vaccine helps the immune system recognise these infections before exposure.

Many adults received measles vaccination in childhood, but records may be incomplete or unavailable. Your clinician may use documented doses and other reliable evidence of immunity when making a recommendation. Measles spreads easily through the air and can cause fever, cough, sore eyes and a widespread rash; vaccination reduces the chance of becoming infected and passing infection to others. It does not treat measles that has already begun.

Tell the clinician if you are pregnant, have a weakened immune system, have had a serious reaction to a previous dose, or use medicines that affect immunity. The vaccine is a live vaccine, so timing and suitability need individual review.

Look for your childhood vaccination record or ask a previous clinic whether it can be retrieved. Arrange a GP consultation if you are unsure about your status, are planning international travel, work in healthcare or childcare, or have been told you were exposed to measles. Do not delay contacting a clinic after a known exposure, because advice may depend on when the exposure occurred.

At an appointment, share your age, previous vaccine dates if known, pregnancy plans, allergies, immune-related conditions and current medicines. Follow the schedule advised for you and keep the updated record for future travel, work or healthcare visits.

If you develop fever, cough, sore or red eyes, or a new rash after possible exposure, call a healthcare service before arriving in person. This allows the team to reduce contact with other people while arranging advice. Read more about Fever and Measles if you need help recognising symptoms.

Seek urgent medical help for trouble breathing, severe drowsiness, confusion, dehydration, a seizure, or rapidly worsening illness. People who are pregnant, immunocompromised, very young, or medically vulnerable should seek advice promptly after exposure or symptom onset.

Ask whether your records show adequate measles protection, whether testing is useful in your situation, and whether MMR vaccination fits your health history. You can also ask about timing around travel, pregnancy, immune-suppressing treatment, and what to do if you have had close contact with someone who has measles.
