Hepatitis B Vaccination: Concerns and Recommendations for Parents

Hepatitis B vaccine

Hello, Director: My child had a negative hepatitis B antibody test during a high school health check-up, so we took them to the hospital to receive a complete course of the hepatitis B vaccine, which consists of three doses (not just an additional dose of the hepatitis B vaccine).
We have completed the first two doses, but the third dose is still pending.
Recently, we learned from the school that the Ministry of Health and Welfare issued a notice on February 26, 2013, stating that for those who have received the hepatitis B vaccination series and show no detectable antibodies, there is no need to administer an additional dose of the hepatitis B vaccine.
My concerns are: 1.
Since my child has already received a complete series of three doses of the hepatitis B vaccine in the past and is now receiving another complete series, could this be harmful to their health? 2.
Should we continue with the third dose to complete the entire vaccination series? Please help me with these questions.
Thank you!

Hello APPLE,
1.
Generally, non-medical personnel do not need to receive additional vaccine doses.

2.
If an additional dose is required, antibody testing should be conducted one month later to determine if further doses (2nd or 3rd) are necessary.
Therefore, it is recommended to test antibodies first before making a decision.

3.
Receiving more vaccines is harmless, so there is no need to worry.
Changhua Hospital cares about your health.

More Info

Hepatitis B vaccination is a crucial aspect of public health, particularly for children and adolescents. Your concerns regarding your child's vaccination status and the implications of receiving multiple doses of the vaccine are valid and important. Let's address your questions and provide some additional context regarding Hepatitis B and its vaccination.

1. Safety of Repeating the Vaccination Series: It is generally safe to receive additional doses of the Hepatitis B vaccine, even if the individual has already completed the initial series. The vaccine is made from a non-infectious component of the virus, which means that it cannot cause the disease. In cases where a person has received the vaccine but does not show detectable antibodies, it is often due to individual variations in immune response rather than a failure of the vaccine itself. Therefore, repeating the vaccination series is not harmful and can help ensure that the individual develops adequate immunity.

2. Completing the Third Dose: It is advisable to complete the vaccination series with the third dose. Completing the series is important for ensuring that your child has the best chance of developing immunity against Hepatitis B. The Centers for Disease Control and Prevention (CDC) recommends that individuals who have not developed antibodies after the initial series should receive a second series of the vaccine. However, since your child is already in the process of receiving the second series, it is beneficial to finish the third dose to maximize the likelihood of a robust immune response.

Additional Considerations
- Understanding Hepatitis B: Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic diseases. Chronic Hepatitis B can lead to serious health issues, including liver cirrhosis and liver cancer. The virus is primarily transmitted through contact with infectious body fluids, such as blood, semen, and vaginal secretions. Vaccination is the most effective way to prevent Hepatitis B infection.

- Vaccination Schedule: The Hepatitis B vaccine is typically administered in a series of three doses. The first dose is given at birth, followed by the second dose at 1-2 months of age, and the third dose at 6-18 months. For older children and adults who have not been vaccinated, the same three-dose schedule applies.

- Monitoring Antibody Levels: After completing the vaccination series, it is possible to check for the presence of antibodies to determine if the vaccination was effective. If the antibody levels are low or undetectable, a healthcare provider may recommend additional doses or a different vaccination strategy.

- Public Health Recommendations: The CDC and the World Health Organization (WHO) recommend routine Hepatitis B vaccination for all infants, children, and adolescents. For adults at risk, vaccination is also encouraged. The benefits of vaccination far outweigh the risks, as the vaccine is safe and effective.

In conclusion, it is safe for your child to complete the third dose of the Hepatitis B vaccine, and doing so will help ensure adequate protection against the virus. If you have further concerns or if your child has specific health conditions, it is always best to consult with a healthcare provider for personalized advice. Vaccination is a key preventive measure in protecting against Hepatitis B and promoting overall health.
