As parents know, babies need to be vaccinated against hepatitis B after birth to effectively prevent infection and protect their health. However, I believe many parents still have some questions about the hepatitis B vaccine.

 

Can hepatitis B vaccine prevent liver cancer?

 

Hepatitis B virus infection is the main cause of primary liver cancer. Hepatitis B vaccination can safely and effectively prevent hepatitis B caused by hepatitis B virus infection and primary liver cancer caused by hepatitis B. Therefore, hepatitis B vaccine is called “the world’s first anti-cancer vaccine” by the World Health Organization.

 

What are the major hepatitis B vaccines?

 

There are three main types of hepatitis B vaccines currently in use, all of which are recombinant vaccines, depending on the manufacturing process: hepatitis B vaccine (brewer’s yeast), hepatitis B vaccine (Hansen’s yeast), and hepatitis B vaccine (CHO cells). All three types of hepatitis B vaccines are safe and effective, so parents can be assured that their babies will be vaccinated.

 

How to vaccinate my baby against hepatitis B after birth?

 

According to the national immunization program, healthy babies should receive the first dose of hepatitis B vaccine within 24 hours after birth, and receive the second and third doses of hepatitis B vaccine at the age of 1 month and 6 months, respectively. Critically ill newborns, such as very low birth weight infants, severe birth defects, severe asphyxia, respiratory distress syndrome, etc., should receive the first dose of hepatitis B vaccine as soon as their vital signs stabilize.

Can premature and low birth weight infants receive hepatitis B vaccination at birth?

 

Premature babies and low birth weight babies are not contraindicated for hepatitis B vaccination, as long as they are in good health, they should receive hepatitis B vaccination in a timely manner.

 

Does my baby need to receive the hepatitis B vaccine after receiving 3 doses of hepatitis B vaccine according to the procedure?

 

In general, babies who have completed 3 doses of hepatitis B vaccination according to the 0, 1 and 6 months program can have good immune protection and generally do not need to receive a supplemental hepatitis B vaccination. However, for key groups, such as those whose mothers are HBsAg positive or have hepatitis B infection in the family, HBsAg and anti-HBs should be tested 1 to 2 months after completing the third dose of hepatitis B vaccination, and if HBsAg is found to be negative and anti-HBs is less than 10 mIU/ml, they can continue to receive 3 more doses of hepatitis B vaccination according to the 0, 1 and 6 months immunization program.

 

How can babies whose mothers are HBsAg-positive receive hepatitis B vaccination?

 

If the mother of the baby is found to be positive for HBsAg during prenatal screening, please do not worry, you can follow the doctor’s instructions to give the first dose of hepatitis B vaccine after birth along with 100 international units of hepatitis B immunoglobulin (HBIG) intramuscularly at different (limb) sites, and complete the second and third doses of hepatitis B vaccine at the age of 1 month and 6 months respectively, which can effectively block the vertical transmission of hepatitis B virus from mother to child, and the key is still free of charge.

 

If the serum test is positive for HBsAg, can I still receive hepatitis B vaccination?

 

Although hepatitis B vaccination is safe, if the serum test is positive for HBsAg, the body is already infected with the hepatitis B virus, and in this case, vaccination with the hepatitis B vaccine cannot stop the infection of the hepatitis B virus, so there is no need to receive the hepatitis B vaccine.

 

Do adults need hepatitis B vaccination?

 

Adults who have not received the hepatitis B vaccine or who have not received the full vaccination or whose vaccination history is unknown and who are 18 years of age or older can receive the hepatitis B vaccine according to the principle of “informed consent and voluntary self-payment”, especially those who are at high risk of infection (such as medical personnel, those who are frequently exposed to blood, those who work in childcare institutions, organ transplant patients, those who frequently receive blood transfusions and blood products, those who are immunocompromised, those who are prone to trauma, family members of those infected with the hepatitis B virus, those who are at risk of sexual exposure and those who inject drugs intravenously) should receive the hepatitis B vaccine in a timely manner.
