In Taiwan's vaccination policy, the hepatitis B vaccine is administered in three doses: the first dose is given at birth, the second dose at two months, and the third dose at six months.
The government covers the cost for infants, while adults must pay out of pocket, and it is available at major hospitals.

More Info

If you have recently discovered that your Hepatitis B antibodies have disappeared, it is important to take the necessary steps to ensure your protection against the virus. Hepatitis B vaccination is a safe and effective way to prevent infection, and understanding the vaccination process is crucial.

Understanding the Hepatitis B Vaccine
The Hepatitis B vaccine is typically administered in a series of three doses. The standard schedule is as follows:
1. First Dose: At a time of your choosing.

2. Second Dose: One month after the first dose.

3. Third Dose: Six months after the first dose.

This vaccination schedule is designed to provide optimal immunity against the Hepatitis B virus. The vaccine is made from a recombinant DNA technology, which means it does not contain live virus, and therefore, cannot cause Hepatitis B infection.

Steps to Get Vaccinated
1. Consult Your Healthcare Provider: Before getting vaccinated, it’s advisable to discuss your situation with your healthcare provider. They can assess your health history, discuss any potential risks, and confirm that you are a suitable candidate for the vaccine.

2. Schedule Your Vaccination: Once you have the green light from your healthcare provider, you can schedule your vaccination. Many clinics and hospitals offer the Hepatitis B vaccine, and it may also be available at public health departments.

3. Complete the Series: Ensure that you complete all three doses of the vaccine. Skipping doses can lead to incomplete immunity. After the final dose, your body will begin to produce antibodies against the virus.

4. Follow-Up Testing: After completing the vaccination series, it is recommended to have a follow-up blood test to check for the presence of antibodies (anti-HBs). This test is usually done about 1-2 months after the final dose. A protective level of antibodies is generally considered to be 10 mIU/mL or higher.

Understanding Immunity and Antibody Loss
It’s important to note that while the antibody levels may decline over time, the immune memory created by the vaccine remains. This means that if you were to be exposed to the Hepatitis B virus, your body would still be able to mount an immune response, even if the antibody levels are low. However, if your antibody levels fall below the protective threshold, it is advisable to get revaccinated.

Risks of Hepatitis B Infection
Hepatitis B is transmitted through contact with infectious body fluids, such as blood, semen, and vaginal secretions. The virus can survive outside the body for at least seven days, making it crucial to avoid exposure to potentially contaminated materials. If you have concerns about exposure, such as from shared needles or contact with blood, it is essential to discuss these with your healthcare provider.

Conclusion
In summary, if your Hepatitis B antibodies have disappeared, you should definitely consider getting vaccinated again. Follow the vaccination schedule, consult with your healthcare provider, and ensure that you complete the series. Regular follow-up testing will help you monitor your immunity status. Remember, prevention is key, and staying informed about your health is the best way to protect yourself against Hepatitis B.
