title: [Rubella immunity in 20-39 year-old women in Japan: monitoring by the antibody data from a commercial diagnostic laboratory].
abstract: In order to know the rubella immune status of Japanese women aged 20 to 39 years old, we analyzed the hemagglutination-inhibiting antibody titration data on 264,371 sera which were sent to a commercial diagnostic laboratory from gynecology clinics all over Japan during 1999 through 2003. We found that antibody-positive rates remained at about 95% during the period, but, from 2000, geometric mean antibody titers of the positive sera gradually decreased each year. Annual analysis of the data will be useful for monitoring the trend of rubella immunity among Japanese women of childbearing age.
