Measles spread quickly and can be dangerous - protection is simple: get vaccinated!
Swiss recommendations: All persons born after 1963 who have no documented protection against the infection (antibodies or 2 documented vaccinations) should be vaccinated twice with MMR vaccine at a one month interval. In the event of an epidemic in the region or contact with a measles case, vaccination is recommended from the age of 6 months.
