my country is an area with a high incidence of hepatitis B, and mother-to-child vertical transmission is one of the important transmission routes of hepatitis B.
If an expectant mother is infected with hepatitis B virus, it may cause fetal malformation, and hepatitis B virus can directly infect the fetus through the placental barrier, making the fetus a hepatitis B virus carrier at birth. To prevent hepatitis B virus infection, pregnant women should be vaccinated with hepatitis B vaccine before pregnancy. The hepatitis B vaccine is injected according to the procedure of 0, 1, and 6, that is, starting from the month of the first injection, the second injection is injected when one month is reached, and the third injection is injected after 6 months. It is best to be injected between 9 and 6 months before pregnancy. Injections started at 16 months. The immunity rate of hepatitis B vaccine can reach 95%, and the immunity period is more than 7 years. If necessary, a booster injection can be given five or six years after the vaccine is injected.
Both of the above vaccines must be checked before injection to confirm that the person being injected is not infected with rubella and hepatitis B virus.
