Current Trends Rubella Vaccination during Pregnancy -- United
States, 1971-1983 From January 1971 to December 1983, 1,096
pregnant women who received rubella vaccine either within 3
months before or 3 months after their presumed dates of
conception were reported to CDC. These women were followed
prospectively to determine the risk of fetal abnormalities
following exposure to the vaccine. Cendehill and HPV-77

eight infants had serologic evidence of intrauterine infection
(1,3). These eight children were all followed for
