Measles is rare nowadays in the Netherlands but it has not yet been eliminated throughout the world. The Measles vaccine has been a part of the Dutch Immunisation Programme since 1976. Incidence of the disease in the country has reduced dramatically since then.

Persons at risk are adults born between 1965 and 1975 and children under a certain age.
