Immunogenicity and Safety of Inactivated and Live-attenuated HAV Vaccine Among Thai Healthy Children and Adolescents

Summary

Hepatitis A virus (HAV) vaccine is an effective strategy to prevent natural HAV infection. In Thailand, there are 2 types of HAV vaccine available, including inactivated HAV vaccine and live-attenuated HAV vaccine. This study aims to compare the immunogenicity and safety of inactivated and lived-attenuated HAV vaccine among Thai healthy children and adolescents age 18 months to 18 years.
