my country is a large country B, and the hepatitis B infection rate in the crowd is as high as 6.1%. At present, the spread of hepatitis B is mainly blood transmission, maternal and infant communication, and sexual transmission. Among them, maternal and infant communication is the main way to spread, accounting for about 60%.
The so -called maternal and infant transmission is that mothers with hepatitis B transmitted hepatitis B virus to the baby through the placenta, production channel or breastfeeding during pregnancy, which may cause the baby’s death, abortion, premature birth, and suffer from hepatitis B after childbirth.Blocking is particularly important.
Maternal and baby blocking is an important way to eliminate hepatitis.
Newborns born of normal pregnant women, as soon as possible (best within 12 hours) after birth (best within 12 hours), vaccinate a hepatitis B vaccine, and then need to be vaccinated again in the first month and 6th month.1 and 6 procedures to inoculate hepatitis B vaccine, and the probability of hepatitis B is blocked by up to 95%or even 100%.
If it is already known to have hepatitis, go to the hospital for evaluation before pregnancy, and whether you can get pregnant normally.If the hepatitis activity period, you need to be treated first, and then get pregnant after the condition is stable.In the case of stable condition, hepatitis B mothers need to monitor the carriers of liver merit and hepatitis B virus virus every two months after pregnancy, and it is clear whether maternal and infants need to be blocked during pregnancy.
The newborn born of the mother B mother, after birth, in addition to the same as normal newborn, needs to be vaccinated according to the 0, 1, and 6 procedures, and it is necessary to injected the hepatitis B immunohistic ball within 12 hours of birth.100 units of protein, further blocking hepatitis B virus.
Inoculation of hepatitis B vaccine is the most effective way to prevent hepatitis B infection. In addition to newborns, other people who have not vaccinated hepatitis B vaccine also recommend inoculation of hepatitis B vaccine, especially infants and unprepared crowds under 15 years old, as well as high -risk people.Normal people are also vaccinated with hepatitis B vaccine, namely 0, 1, and 6 procedures.
The earliest hepatitis B vaccine is vaccinated, the better. For ordinary people, a hepatitis B vaccine with a three -pin 20 μg is recommended. For those with low immune function and no response after vaccination, it is recommended to increase the dose and needle of the vaccination, that is, the hepatitis B vaccine of 60 μg of one needle.Or then vaccinate a three -needle 20 μg of vaccine and check the hepatitis B surface antibody one month after vaccination. If the titer of the surface antibody is less than 10 international standardized units, the vaccination can be strengthened.
If antibodies are successfully produced after vaccination with hepatitis B vaccine, the protection effect can generally last at least 30 years. Therefore, for those who produce antibodies for the general population, hepatitis B antibodies may not be monitored.When the protection of antibodies is less than 10 standardized units, vaccination should be strengthened.
Note: Women who have not been infected with hepatitis B are safe during pregnancy. In addition to in vaccination of hepatitis B vaccine in accordance with conventional procedures, accelerate the vaccination process of hepatitis B vaccination, that is, the method of vaccination of 0, 1, and 2 has proven to be safety and and have been proven to be safety and and.feasible.
