Abstract:
Objective To study the feasibility and safety of measles vaccination in women of childbearing age and to understand the influence of measles vaccination on the fetal transmission measles antibody level of the infants.Methods From January 1,2012 to December 31,2012,600 women of childbearing age were included in this study.The measles IgG antibody was detected,then all participants were randomized according to the IgG level.The measles IgG antibody of participants in non-vaccinated group was detected predelivery in hospital by enzyme linked-immunosorbent assay (ELISA).That of participants in vaccinated group was detected 3 months after vaccination with measles mumps rubella combined vaccine and predelivery by ELISA.And measles nuclear protein fragment gene (measles virus nucleoprotein,MVN) in the blood was detected by reverse transcription polymerase chain reaction (RT PCR).A total of 368 participants gave birth within 2 years after vaccination,and 357 infants 8 months after birth were healthy.In non-vaccinated group,8 infants were diagnosed with measles within 8 months after birth.Finally,349 8-month infants were enrolled in the study,including 52 whose mothers in high antibody without vaccination group,65 whose mothers in high antibody with vaccination group,110 whose mothers in low antibody without vaccination group and 122 whose mothers in low antibody with vaccination group.The measles IgG antibody levels in the blood of all the 8-month infants were detected.Data were analyzed using t test,one-way ANOVA (Newman-Keuls was used for comparison between groups) and Pearson analysis.Results The measles IgG antibody level of expectant women in high antibody without vaccination group was significantly lower compared to that in high antibody with vaccination group ([268.5±74.9] IU/mL vs [578.3t208.1] IU/mL,Q=15.57,P＜0.01).That in low antibody without vaccination group was also significantly lower than low antibody with vaccination group ([169.4+42.3] IU/mL vs [584.7+195.8] IU/mL,Q=29.54,P＜0.01).The results of MVN RT-PCR after 3 months of vaccination showed no positive bands in all blood samples.Two of the expectant women in high antibody without vaccination group and one in low antibody without vaccination group were positive for MVN bands.Among 8-month infants,the levels of antibody in high antibody without vaccination group and high antibody with vaccination group were (106.3 ± 36.8) IU/mL and (291.8±86.5) IU/mL,respectively,which was statistically different (t=23.33,P＜0.01).Those in low antibody without vaccination group and low antibody with vaccination group were (87.1 ± 26.4) IU/mL and (274.0±72.5) IU/mL,respectively,which was statistically different (t =33.27,P＜0.01).The measles antibody level of expectant women was positively correlated with their 8-month infants (r=0.652,P＜0.01).All 8 infants who were diagnosed with measles were delivered by women without vaccination,and the measles infection rate of infants was significantly different between women with and without vaccination (P=0.002).Condusion It is feasible for women of childbearing age to receive measles vaccination,which can increase the measles IgG antibody level of both expectant women and their infants.
