Abstract
A long-term immunogenicity study of a single dose live attenuated H2 strain hepatitis A vaccine is being conducted in healthy Indian children at KEM Hospital, Pune. 131 of the original 143 children vaccinated in 2004, were evaluated for anti-HAV antibodies 30 months post vaccination (2007). Seroprotective antibody levels ≥20 mIU/mL were demonstrated in 87.8% subjects with an overall GMT of 92.02mIU/mL. No hepatitis like illness was recorded in any of the subjects since vaccinationKeywords
