What should you know about German measles vaccine for adults?

German measles is another name for rubella, a viral infection that can cause a rash, fever, swollen glands and joint pain. Vaccination helps the immune system recognise the virus before exposure.

The rubella vaccine is usually given as part of the combined measles, mumps and rubella vaccine (MMR). Your vaccination history, age, previous infection, immune status and plans for pregnancy can affect whether it is advised.

Rubella infection during pregnancy can harm an unborn baby, so people who may become pregnant should discuss immunity before pregnancy where possible. The MMR vaccine is not given during pregnancy; a clinician can explain suitable timing and follow-up.

Ask a GP or vaccination provider to review your records if you do not know whether you received MMR or another rubella-containing vaccine. They can check whether vaccination is appropriate and explain the schedule for any doses you need.

Tell the clinician about pregnancy, possible pregnancy, immune-system problems, severe allergies, recent vaccinations and medicines that affect immunity. After vaccination, mild soreness, fever or a short-lived rash can occur; seek advice if symptoms worry you.

Contact a GP promptly if you develop a rash with fever or swollen glands after possible exposure to rubella, particularly if you are pregnant or could be pregnant. Avoid close contact with pregnant people until you receive medical advice.

Seek urgent help for breathing difficulty, facial or throat swelling, faintness or widespread hives after vaccination, as these may signal a serious allergic reaction. For non-urgent concerns, a GP consultation can help assess symptoms and vaccination needs.

You could ask: Do my records show protection against rubella? Do I need MMR vaccination or another dose? Is it safe with my medicines or health conditions? How long should I wait before trying for pregnancy?
