Advice for Travellers
Travel may increase an individual’s risk of exposure to measles virus, and facilitate the spread of disease to unvaccinated and susceptible populations. Two doses of MMR vaccine, at least one month apart, are required to give adequate protection.
It should be confirmed that children have received their recommended doses of MMR at 12-13 months of age and again pre-school around 3 years 4 months. Unvaccinated adults who have not had measles themselves should seek advice from a healthcare professional regarding measles vaccination.
