The impact of a rubella prevention policy on the outcome of rubella in pregnancy.

Surveillance of rubella vaccination in schoolgirls has continued intensively in Edinburgh since 1970. Screening for rubella antibody of all women attending antenatal clinics has been available since 1974. The analysis of cases of rubella occurring in pregnancy during an outbreak in 1979 confirmed the efficacy of schoolgirl vaccination in the city but indicated poor implementation of postnatal vaccination. Eighteen (67%) of 27 proven cases occurred in women who were screened in previous pregnancies and not immunized. Of the total of 13 liveborn infants the only two with congenital rubella defects were born to mothers in this group. Rubella immunization of schoolgirls and women of childbearing age must receive continued intensive effort if the problems of rubella in pregnancy are to be eradicated.
