Patient's question:
Ten years ago, I was diagnosed with hepatitis B (). Two years later, I received treatment for a year, but then stopped. Until today, during my company's health check-up, I found out that all the indicators had turned negative. So, do I still need to get vaccinated?Doctor's answer:
If it is confirmed that all five hepatitis B tests are negative, the hepatitis B vaccine can be administered under anesthesia. Administering the hepatitis B vaccine is the most critical measure in China's prevention efforts and in curbing the prevalence of hepatitis B. Currently, the common vaccination schedule involves doses at 0, 1, and 6 months, with each dose containing 10-20 micrograms of recombinant vaccine. For high-risk populations, the dosage can be appropriately increased, achieving a surface antibody conversion rate of over 90%. After vaccination, as time passes, the surface antibody levels of some individuals will gradually rise. If the level is below 10 mIU/ml, it is recommended to receive the full course of three hepatitis B vaccine shots. If the level is between 10-100 mIU/ml, it is recommended to receive one booster shot of the hepatitis B vaccine.
