1. What Is Hepatitis B? Why Should Pregnant Women Be Concerned?

Hepatitis B is an infectious disease caused by the hepatitis B virus (HBV), which directly affects the liver. If left untreated, it can lead to serious complications such as cirrhosis, liver failure, and liver cancer.

For pregnant women, hepatitis B is especially dangerous because it can be transmitted to the baby during childbirth, significantly increasing the risk of congenital infection. Statistics show that if a mother has hepatitis B and does not take preventive measures, the risk of transmitting the disease to the baby is up to 90%.

2. Can Pregnant Women Get the Hepatitis B Vaccine?

The answer is YES, but under specific conditions:

• If the mother has never been vaccinated and is at high risk of infection, doctors may recommend the vaccine for protection.
• If the mother has received partial vaccination but not the full series, she can continue the schedule during pregnancy.
• If the mother is already infected with hepatitis B, vaccination is not necessary, but regular monitoring and a treatment plan are crucial.

Note: The hepatitis B vaccine during pregnancy should only be administered under a doctor’s supervision to ensure safety.

3. When Should Pregnant Women Get the Hepatitis B Vaccine?

The best time to get the hepatitis B vaccine is before pregnancy, allowing the body to develop immunity to protect both mother and baby.

However, if a woman becomes pregnant without prior vaccination, she can still follow this schedule:

• Dose 1: As soon as pregnancy is confirmed (if no prior immunity).
• Dose 2: One month after the first dose.
• Dose 3: Six months after the first dose (can be administered postpartum if necessary).

Additionally, doctors may recommend a blood test to determine whether vaccination is needed.

4. Does the Hepatitis B Vaccine Affect the Baby?

According to multiple studies, the hepatitis B vaccine is safe for pregnant women and does not harm the baby. It is an inactivated vaccine (does not contain live virus), so there is no risk of infection.

However, expectant mothers should still follow medical advice to ensure the best health outcomes.

5. Who Should Get the Hepatitis B Vaccine During Pregnancy?

Doctors often recommend the vaccine for pregnant women who are at high risk of infection, including:

• Those with family members who have hepatitis B (parents, siblings, spouse, etc.).
• Healthcare workers or individuals who frequently come into contact with blood or bodily fluids.
• Those with a history of blood-transmitted diseases.
• Women with multiple sexual partners or a partner infected with hepatitis B.

If you fall into any of these categories, consult a doctor for a proper vaccination plan.

6. How to Prevent Mother-to-Baby Hepatitis B Transmission

In addition to vaccination, mothers with hepatitis B should take the following preventive measures to protect their babies:

6.1. Get a Hepatitis B Test During Pregnancy

All expectant mothers should get tested for hepatitis B during the first trimester. If the test is positive, doctors will recommend appropriate treatment to reduce transmission risks.

6.2. Vaccinate the Baby Immediately After Birth

If the mother has hepatitis B, the newborn must receive two shots immediately after birth:

• Hepatitis B vaccine: Within 12–24 hours of birth.
• Hepatitis B immune globulin (HBIG): Given at the same time to provide additional protection.

The baby must then complete the full vaccination schedule for effective prevention.

6.3. Is Breastfeeding Safe?

Mothers with hepatitis B can still breastfeed if the baby has received the full vaccine and immune globulin. However, they should maintain good nipple hygiene and avoid cracked or bleeding nipples.

7. Conclusion

Hepatitis B is a serious disease, but pregnant women can get vaccinated to protect themselves and their babies. The vaccine should be administered under medical supervision to ensure safety.

To prevent transmission to the baby, expectant mothers should get tested early, follow vaccination guidelines, and ensure their baby receives proper immunization after birth.
