ABSTRACT
Objectives:
To assess immunogenicity of a single dose of live attenuated hepatitis A vaccine in Indian children, ten years after immunization.Methods:
Of 143 children vaccinated in 2004, 121 children were evaluated in 2014, clinically and for anti-HAV antibodies.Results:
13 children were early vaccine failures who received two doses of HAV vaccine subsequently. 106 (98%) of 108 remaining children had seroprotective levels with a geometric mean titer of 100.5 mIU/mL. On analysis of all 121 children, the immunogenicity was 87.6%.Conclusion:
Single dose of live attenuated hepatitis A vaccine provides long-term immunity in Indian children.
