The article was consulted professionally by Master, Dr. Nguyen Hai Ha – Head of Vaccine Unit – Pediatric Outpatient Department, Share99 Times City International Health Hub.

It is estimated that about 10-20% of the population is infected with hepatitis B virus, of which the incidence of hepatitis B virus in pregnant women is 10-16%. To prevent the risk of mother-to-child transmission of hepatitis B virus, the World Health Organization and the Ministry of Health need to vaccinate infants against hepatitis B. However, when should hepatitis B vaccination be given to babies to bring the best protection effect to the child?

1. Why vaccinate babies against hepatitis B?

Hepatitis B is a disease that causes acute or chronic inflammation and necrosis of liver cells, which is the leading cause of cirrhosis and liver cancer in the world. Hepatitis B is caused by the hepatitis B virus. It is estimated that every year in the world at least one million people die from liver diseases caused by the hepatitis B virus.

Mother-to-child transmission is one of the main routes of transmission of the hepatitis B virus. During pregnancy, the metabolism between mother and child takes place in vegetable cakes, mother and child blood do not come into direct contact with each other so infection rarely occurs. Transmission is mainly at the time of birth, when the uterus and blood vessels where the contractions are attached cause the mother and child's blood to come into contact or the child can also be infected by passing through the mother's vagina.

  • If the mother has HBsAg and HbeAg positive, then 70-90% of babies born will be infected with hepatitis B virus.
  • If the mother has HbsAg positive, HbeAg is negative, then the rate of infection is 10-40%.

In addition, family members who regularly care for liver B infection are also capable of transmiting the virus to the child when in direct contact with scratches, bleeding.

Infection with hepatitis B virus at an early age will be a major health risk, the earlier the person with the hepatitis B virus load, the higher the risk of liver diseases. According to the study, up to 80-90% of children infected with hepatitis B virus in the first year of life will have chronic hepatitis, high risk of cirrhosis, liver cancer later, and will be the main source of viral infection for the community.

Vaccination against hepatitis B for babies will help the child's body produce antibodies against hepatitis B virus, which is an effective method of protecting children from one of the risks that are threatening human health. Hepatitis B vaccines can be given on the same day as other vaccines that will not affect the child's ability to respond to immunity or health.

2. When should I get vaccinated against hepatitis B?

Vaccination against hepatitis B for babies should be carried out as soon as possible, it is best to do it within 24 hours after birth. Injections taken during this time can protect 85-90% of children from contracting the hepatitis B virus from their mother. If the next day is injected (from 24-48 hours) the protective effect will be reduced to only 50-57%.

Vaccinating children against hepatitis B in the early hours after birth helps the child's body to produce antibodies against the hepatitis B virus that is growing in exposed young people during childbirth. This is really a fight where if a child is not vaccinated against hepatitis B early after birth, he has virtually no chance of winning.

Hepatitis B vaccination as soon as possible

If the mother tests for HbsAgnegative , in theory she is not infected with the hepatitis B virus but the 24-hour post-birth hepatitis B vaccination must still be carried out. Because it is possible that the mother's test results are incorrect, she is falsely negative, she is suffering from a mutative strain of hepatitis B virus that the blood test does not detect. Or although the baby is not infected from the mother of babies who may be infected with hepatitis B virus from medical staff, relatives, caregivers of babies infected with hepatitis B virus. If the mother has hepatitis B (positive HbsAg test), vaccination and anti-hepatitis B serum should be given to the child within 24 hours of birth, it is best to 12 hours to ensure the child is not infected

Vaccination against hepatitis B for babies in the 24 hours after birth is considered a golden time, a simple but protective injection is very important in the life of the child, the danger of hepatitis in babies is that up to 90% of cases will not have specific clinical symptoms, the disease develops silently and it is not until decades later that there are manifestations such as cirrhosis, liver cancer.

3. Which cases delay hepatitis B vaccination 24 hours after birth?

Vaccination against hepatitis B 24 hours after birth is extremely necessary, however, there are some cases where it is necessary to postpone vaccination of children under Decision 2470 / QD-BYT on pre-vaccination screening issued on June 14, 2019 prescribing the suspension of hepatitis B vaccination for children as follows:

  • The child has an emergency ≥ 37.50 C or hypothermia ≤ 35.50 C (armpit temperature), vaccinated when his health stabilizes.
  • Babies with gestational age <28 tuần thai, tiêm vắc-xin phòng viêm gan B khi trẻ đủ 28 tuần thai (tính cả tuổi thai).
  • Children with weight <2000g mà mẹ có HBsAg âm tính. In case the mother has a positive HBsAg or does not test, it is necessary to vaccinate the child against hepatitis B.
  • Children with congenital heart diseases have an increase in pulmonary artery pressure (≥ 40mmHg).

4. Hepatitis B vaccination prices for infants

The hepatitis B vaccine is part of the Ministry of Health's expanded vaccination program, which is available to all local health lines, hospitals, clinics with obstetrics and gynecology and is completely free for children. After receiving the first hepatitis B vaccine in the hospital for 24 hours after birth, the child will be continued to receive hepatitis B vaccine at 2 months of age, 3 months of age and 4 months of age at commune and ward health stations in the area of residence. At this time, the hepatitis B vaccine will be combined with the diphtheria-whooping cough-tetanus-Hib vaccine into a 5-in-1 vaccine.

In service vaccination programs or some hospitals that use service vaccines, hepatitis B vaccines will have to cover costs depending on the type of vaccine. After the newborn hepatitis B shot, the hepatitis B vaccine will be repeated at 2,3,4,18 months in a combination of 6 in 1 or 5 in 1.
