由于母体抗体的持续存在会影响婴儿免疫的成功,所以2次改变了婴儿接种麻疹疫苗的推荐年龄。本研究皆在测定≤12月龄时接种麻疹疫苗并可检出麻疹抗体者的百分率和年龄,以及那些未检出麻疹抗体者对再接种疫苗的应答。
Since the persistence of maternal antibodies affects the success of infant immunization, the recommended age of infant immunization with measles is changed twice. In this study, both the percentage and age of those who were immunized against measles at measles vaccine ≤12 months of age and those who did not have measles antibody were tested for response to the vaccine.
