title: [Immune response of rubella vaccine in the populations with different age groups].
abstract: The natural immunity status in different age groups was investigated. The positive rate of HI antibody under the age of 4 was less than 25%. The natural immunity level increased gradually with age and the positive rate of the antibody reached 80% among the group aged 13-25. Rate of seroconversion was 100% in any age group one month after immunization, and GMT rose from 13.33 to 243.16. It was suggested that immunogenicity of domestic attenuated live rubella vaccine BRD II was satisfactory. For the population with positive-antibody before immunization, the total GMT rose from 189.59 to 259.00 after vaccination and the difference between immunization before and after was highly significant. According to the above result, we suggested that the vaccination strategy for rubella among young children and women of child-bearing age should be implemented.
