How long does MMR vaccination take to work for rubella?

The vaccine trains the immune system to recognise rubella before an exposure occurs. One dose may not provide the same protection as a complete vaccination schedule, so your clinician may recommend another dose when your records or circumstances call for it. Protection is not immediate on the day of vaccination.

Rubella can be especially serious during pregnancy because infection can harm an unborn baby. MMR is a live vaccine and is generally avoided during pregnancy; discuss pregnancy plans and recent exposure with a healthcare professional.

Check your vaccination record and keep the appointment for any advised follow-up dose. Until a clinician confirms that your vaccination schedule is complete, take practical steps to reduce exposure to infectious illness and tell a healthcare professional if you may have been exposed to rubella.

A mild fever, sore arm or brief rash can occur after vaccination. Rest, drink fluids and seek advice before taking medicine if you are pregnant, immunocompromised or have had a serious vaccine reaction before.

Contact a healthcare professional promptly after a possible rubella exposure, especially if you are pregnant or could be pregnant. Seek urgent help for breathing difficulty, facial swelling, collapse or another sign of a severe allergic reaction after vaccination.

Ask whether your vaccination record shows a complete MMR schedule, when protection is expected to be established, and what precautions are appropriate after a possible rubella exposure.
