康医生:我是一位乙型肝炎病毒表面抗原阳性的孕妇,目前已怀孕7个月(即28周),在某三甲医院做产检。医师说我应该打乙型肝炎免疫球蛋白,而且已经打晚了,所以以后每个月要注射1针乙型肝炎免疫球蛋白(200国际单位),连续注射 Dr. Kang: I am a pregnant woman who is positive for hepatitis B virus surface antigen. She is currently pregnant for 7 months (ie 28 weeks) and is undergoing childbirth in a top-tier hospital. The physician said that I should have hepatitis B immunoglobulin, and it has already been late, so I will inject 1 dose of hepatitis B immunoglobulin (200 IU) once a month for continuous injection
