Patient's question:
I am 19 years old. I received the hepatitis A vaccine at the age of 2. Now the school recommends getting another dose. How many times should one receive the hepatitis A vaccine in a lifetime?Doctor's answer:
Hello, after receiving the hepatitis A vaccine, antibodies must be produced in the body before it can take effect in preventing the disease. Some people may not be able to produce antibodies due to their own immune system. Once antibodies are produced, they can only provide preventive effects under normal circumstances. If exposed to a large amount of hepatitis A virus, you may still contract hepatitis A. Generally, the vaccine is effective for 5 years, and a booster shot is recommended after that period. Therefore, you should have gotten another shot. After completing the three doses, you should visit the hospital three months later for a liver function test to determine if the vaccination was successful.Doctor's inquiry: I hope this explanation is helpful to you.
Additionally, during the treatment of hepatitis A, the patient's dietary condition and care are also very important. The patient must pay attention to rest.
