How many doses of the hepatitis A vaccine are required?
Disease description:
Today, my child’s doctor advised me to bring my child in for the hepatitis A vaccine. As I’m not very familiar with this topic, I’d like to ask in advance: How many doses of the hepatitis A vaccine are required?

Dr. Jiang Weimin
Hepatitis A vaccines are divided into two types: inactivated hepatitis A vaccine and live attenuated hepatitis A vaccine. For the inactivated hepatitis A vaccine, two doses are typically required, administered six months apart. In contrast, the live attenuated hepatitis A vaccine usually requires only a single dose. Compared with the live attenuated hepatitis A vaccine, the inactivated hepatitis A vaccine offers superior stability and achieves effective immunity.
