The difference between the attenuated B brain vaccine and the inactivated B brain vaccine is that the attenuated vaccine has a live virus component and consists of 2 doses, which is a free vaccine, while the inactivated B brain vaccine does not contain a live vaccine component and consists of 4 doses, which is a self-funded vaccine.
Both the attenuated B brain vaccine and inactivated B brain vaccine are vaccines to prevent B encephalitis virus. Children are susceptible groups, and epidemic B encephalitis will lead to high fever, convulsions, meningeal irritation signs, which may affect children’s cerebral neurodevelopment, and the case fatality rate is high, so it is recommended to be actively vaccinated, and according to World Health Organization’s “Position of Vaccine for Epidemic B Encephalitis”, it is more recommended to have the attenuated B brain vaccine.
Brain B attenuated vaccine is produced as a vaccine containing live attenuated virus, with low pathogenicity and stronger immunogenicity. 2 doses of the vaccine in total, the protection rate can be up to 90%, and it belongs to the category of planned vaccination in our country, which is a free vaccine.
The inactivated vaccine for encephalitis B does not contain active viral components, retaining antigenicity, with a total of 4 doses, the protection rate of 60-90%, and is a self-funded vaccine.
Hepatitis B attenuated vaccine has obvious advantages in comparison, parents are recommended to vaccinate their children in time to ensure the protective effect.
