In the interval 1962-1963, about 100 children were immunized by live attenuated measles vaccines.
1) In the following 20 months after vaccination, 57 vaccinees were exposed to natural measles. 4 (7%) in these children suffered from measles, 2 from regular measles; 2 from modified measles. In the control group children dwelling the same area, outbreaks of natural measles were observed. 75% or greater of those suffered from regular measles.
2) In the children not exposed to natural measles, NT antibody level persisted undiminished or slightly decreased in 18 months after administration of live vaccines.
3) The vaccinees resisted firmly against the re-vaccination of live vaccines inoculated in 12 months after first vaccination.
4) Booster effect was observed both after the exposure to natural measles and after the re-vaccination.
