A netizen in Shaanxi left a message to inquire, how to choose the attenuated hepatitis A vaccine and the inactivated hepatitis A vaccine?
Hepatitis A vaccine, hepatitis A vaccine for the prevention of viral hepatitis, is divided into hepatitis A attenuated vaccine and hepatitis A inactivated vaccine, and the process is different.
The hepatitis A attenuated vaccine requires only one dose at 18 months of age, while the inactivated hepatitis A vaccine requires two doses at 18 months and 24 months of age, at least six months apart. The earliest age of hepatitis A inactivated vaccine is set at 12 months on the instructions.
At present, five provincial-level administrative regions in Chinese mainland, Beijing, Tianjin, Shanghai, Zhejiang and Jiangsu, are vaccinated with inactivated hepatitis A vaccine free of charge, and the use of hepatitis A attenuated vaccine has been stopped. Other provincial-level administrative regions in the mainland let parents make a choice, either free attenuated hepatitis A vaccine or inactivated hepatitis A vaccine at their own expense, which led to this netizen's consultation.
If you do not consider the cost, the first choice is hepatitis A inactivated vaccine, developed countries or regions in the world are basically using hepatitis A inactivated vaccine, and several wealthy provincial-level administrative regions in China's mainland are vaccinated with hepatitis A inactivated vaccine for free, which is safer, and the use of hepatitis A attenuated vaccine is stopped.
If you are more concerned about the cost, you can use whichever is free, after all, the attenuated hepatitis A vaccine is not so bad, and you can even get one less shot. The main disadvantage of hepatitis A attenuated vaccine is that it cannot be used in immunocompromised patients, and it is still rare in the population.
The above is my personal opinion and is for reference only.
