Acute hepatitis A infection in individuals with pre-existing chronic liver disease may cause severe illness and fulminant hepatic failure. This multicenter study compared the safety and immunogenicity of inactivated hepatitis A vaccine in patients with chronic liver disease and healthy subjects. A total of 475 subjects older than 18 years received two doses of inactivated hepatitis A vaccine. Local injection site symptoms were the only common adverse events. After one dose, 93% of healthy subjects developed antibodies against hepatitis A virus compared to 73% of subjects with chronic hepatitis C and 83% of subjects with chronic liver disease form non-viral causes. However, greater than 94% of all subjects had antibodies against hepatitis A virus after receiving two doses of vaccine. In conclusion, hepatitis A vaccine is safe and most likely effective in individuals with chronic liver diseases.
