Hepatitis A Clinical Trial
Official title:
Phase 4 Clinical Trial to Assess the Safety, Immunogenicity,Three-year Immune Persistence of Inactivated Hepatitis A Vaccine (HAV) and Live Attenuated HAV Vaccine
The purpose of this Phase 4 trial is to assess the safety, immunogenicity, three-year immune persistence of inactivated hepatitis A vaccine (HAV) and live attenuated HAV vaccine.
Hepatitis A refers to liver inflammation caused by infection with the hepatitis A virus. HAV is is one of the most common hepatitis viruses that can cause hepatitis in China. The data from the phase 1, 2 and 3 trials suggested that both inactivated hepatitis A vaccine and live attenuated hepatitis A vaccine had a clinically acceptable safety and good immunogenicity for healthy Chinese people. ;
