[Measles vaccination with split vaccines and living vaccines (author's transl)].

Two vaccination groups were observed over four years. One group received multiple preliminary vaccinations with measles split vaccine and were subsequently immunised with measles live vaccine. The second group received live vaccine only. The protection from the live vaccine, with and without the preliminary vaccination, must be considered very good, while the protection of a preliminary vaccination with split vaccine is only sufficiently effective for 1 1/2 to 2 years. All children-whether pre-vaccinated with split vaccine or not-should be protected against measles with live vaccine from the second year of life.
