Baoma are worried that babies will be infected with hepatitis B, but many people say that it is difficult for babies to be infected with hepatitis B, which makes Baoma puzzled. After all, hepatitis B is a highly infectious disease, and babies have low immunity, so they should be extremely easy to be infected. So, why is it that babies are not easily infected with hepatitis B?
Now all newborns will be injected with hepatitis B vaccine. In the past, when there was no hepatitis B vaccine, hepatitis B was mainly transmitted from mother to child. That is to say, newborns are easy to be infected by their mothers with hepatitis B virus. Now all newborns will be injected with hepatitis B vaccine, especially hepatitis B mothers. In addition to hepatitis B vaccine, they will also be injected with hepatitis B immunoglobulin. In this case, the possibility of newborns being infected with hepatitis B virus is very low.
In 1992, China has included hepatitis B vaccine vaccination as one of the contents of the national immunization plan. The methods adopted are: ① The infants of HBsAg negative mothers should be injected with 5 μ g recombinant yeast hepatitis B vaccine or 20 μ g Chinese hamster oocyte hepatitis B vaccine once every 24 hours, one month and six months after birth; ② Babies born to HBsAg positive or HBsAg and HBeAg double positive mothers should be given hepatitis B vaccine as soon as possible after birth, preferably once within 12 hours, one month and six months.
In addition, in order to prevent hepatitis B B virus from being transmitted to newborns through latex, mothers need to block hepatitis B virus before delivery and after vaccination of infants, so that the hepatitis B virus can be blocked. If the liver function is normal, breast feeding can be carried out at this time.
