After 3-year studies on development of further attenuated live measles vaccines by Japan Measles Vaccine Research Commission, two kinds of vaccines of different strains were licensed for optional use in 1971. In 1978, periodical immunization against measles was started using BIKEN CAM-70 vaccine, Takeda Schwarz-FF8 vaccine and Kitasato AIK-C vaccine.
