Whether or not the Hepatitis A vaccine is self-funded has to do with the family’s financial situation and other factors. Hepatitis A vaccine is a vaccine used to prevent hepatitis A. There are two types of vaccines, free and self-pay. The live attenuated hepatitis A vaccine is free, while the inactivated hepatitis A vaccine requires a fee. The live attenuated hepatitis A vaccine requires only one dose at 18 months of age, while the inactivated hepatitis A vaccine requires the first dose at 12 months of age and the second dose at intervals of 6 to 12 months. Both live attenuated hepatitis A vaccine and inactivated hepatitis A vaccine have better immunization effect, and the protection effect lasts for a longer period of time after immunization for both adults and children, and can even last for life. In general, both free and self-funded hepatitis A vaccines have obvious immunization effects, and it is recommended to consult the local vaccination department according to the financial situation of the family.
