Every pregnant mother with hepatitis B has a strong desire to: not infect her child! Can my doctor do this for me? Happily, the current state of medicine has largely made this possible. In the past, without effective measures to interrupt mother-to-child transmission, a mother with a high viral load had a 90% or higher chance of transmitting the disease to her child. And, 85% to 90% of infected babies will develop into chronic hepatitis B carriers, which is why China has become a major hepatitis B country. First, let’s analyze the ways in which a mother can transmit hepatitis B to her fetus. The rate of HBV infection in utero is 9.1% to 36.7%. 2, intrapartum transmission: is the main route of mother-to-child transmission of HBV, accounting for 40% to 60%. 3, postpartum transmission: with contact with breast milk and mother’s saliva related. China in the past decade or so, through the method of joint immunization of newborns to avoid most of the mother-to-child transmission. How is this done? A full dose of high potency hepatitis B immunoglobulin + hepatitis B vaccine is given within 12 hours of the child’s birth, and then, one dose each of hepatitis B vaccine is given at 1 month and 6 months of life. This method of vaccination has been widely practiced in various medical institutions in China. The overall success rate reported is in the range of 90-97.5%. Therefore, most hepatitis B mothers no longer have to worry about their babies getting hepatitis B! All you need to do is to do your maternity checkup, inform your doctor of your hepatitis B condition, and the hospital will help you complete the co-immunization! In addition, mothers often ask during the clinic if it is useful to apply high-valent hepatitis B immunoglobulin in late pregnancy. In fact, this method has been proven to be useless.
