Abstract
OBJECTIVE:To observe the safety and immunological effects of Measles-mumps-rubella(MMR)attenuated live at-tenuated vaccine in children. METHODS:300 children aged 8-12 months receiving inoculation were selected from Changsha Hospi-tal for Maternal and Child Health Care during Jan. 2015-Apr. 2016 to observe safety and immunological effects. Those children were divided into MMR group,measles vaccine group,mumps vaccine group and rubella vaccine group according to vaccine type, with 75 cases in each group. The occurrence of ADR in 72 h were compared among 4 groups after inoculation;venous blood of chil-dren was collected before vaccination and 5 months after vaccination,and the antibody positive test was carried out by micro coagu-lation inhibition (HI) test;HI antibody titer was recorded after immunization,and positive rate and genometric meantiter(GMT) were calculated. RESULTS:The incidence of ADR in 4 groups were 9.33%,8.00%,8.00% and 10.67%,respectively. No local ADR was found in 4 groups;among systemic ADR,the incidence of fever was higher than that of other clinical manifestations,be-ing 4.00%,4.00%,4.00% and 5.33%;there was no statistical significance in the incidence of ADR among 4 groups(P>0.05). Measles,mumps and rubella antibody positive rates of MMR group were 100%,92.00% and 100%,respectively;antibody posi-tive rates of measles vaccine group,mumps vaccine group and rubella vaccine group were 100%,85.33% and 100%,respective-ly;there was no statistical significance in same antibody positive rate among 4 groups(P>0.05). GMT of measles in MMR group and measles vaccine group were 1∶41 and 1∶27,that of mumps in MMR group and mumps vaccine group were 1∶6.3 and 1∶6.2, there was no statistical significance (P>0.05);GMT of rubella in MMR group and rubella vaccine group were 1∶320 and 1∶849, with statistical significance (P<0.05). CONCLUSIONS:Compared to traditional single vaccine,MMR dose not increase the inci-dence of ADR and not influence positive rate,but GMT of rubella increases significantly,to which should be paid attention.关键词
