Young people who missed their MMR vaccines as children are vulnerable, especially if gathered in large numbers at an event. It should be confirmed that children and young people have received their recommended doses of MMR at 12-13 months of age and again pre-school around 3 years 6 months. Unimmunised adults who have not had the disease themselves may consider vaccination if thought to be at risk. Two doses of MMR vaccine are required to give adequate protection.
