what is the mmr vaccine?
A dose of MMR vaccine is usually given to children aged 12-13 months. A second dose is usually given as a preschool booster. The MMR vaccine is very safe and is not linked with autism or bowel diseases. MMR stands for measles, mumps and rubella. These are three different diseases which are caused by three different viruses. The vaccines given to immunise against measles, mumps and rubella (MMR) are all combined into one injection-the MMR vaccine. Even if you think your child has already had one of these diseases, your child should still have MMR immunisation.
