The most effective way of preventing measles is the measles, mumps and rubella (MMR) vaccine.
The first MMR vaccination should be given when your child is around 13 months old. A booster is given before your child starts school.
If your child is younger than 13 months and you think they may have been exposed to the measles virus, see your GP immediately.
The MMR may be given if they are over six months old, or they may be given antibodies for immediate protection if they are younger than six months old.
The NHS Choices website has more information on the MMR jab.
2013 is expected to be the worst year for measles in the UK for the past two decades. Read more about the illness and how it is treated.
