Does rubella immunity predict measles immunity? A serosurvey of pregnant women

Abstract

Background. This study was undertaken to determine whether rubella immunity infers measles immunity in pregnant women. Methods. Stored serum samples were obtained from the Iowa State Hygienic Laboratory for evaluation of rubella and measles immunities with IgG enzyme-linked immunosorbent assay. Results. Nine hundred serum samples were obtained for testing. The average age of the women at the time of antepartum serum collection was 28 (range, 14 to 44) years. Measles and rubella immunity were 88% and 98%, respectively; there was no effect of immunity status by age identified. Eighty eight percent of those with rubella immunity were also measles immune.There was no association between paired rubella and measles immunity identified, P
