Patient's question:
My husband received the hepatitis A vaccine during his 7 years of university, but he didn't know which type of hepatitis A vaccine he was vaccinated with. Now his new job requires him to work frequently, and I want him to get the hepatitis A vaccine.Doctor's answer:
The hepatitis A vaccine is not a blood product. It is absolutely impossible to contract hepatitis A or other diseases after vaccination. Please use it with confidence. The attenuated live vaccine for hepatitis A is recommended for two doses to achieve lifelong automatic immunity. The full automatic immunity for this vaccine consists of two injections: one for the primary automatic immunity, followed by another injection within 6-12 months to provide lifelong and boosting immunity. In other words, the full course of the hepatitis A vaccine requires two injections. After completing the two injections of the hepatitis A vaccine on schedule and according to the standard anesthetic procedure, the body will produce hepatitis A antibodies that provide lifelong immunity.
