Randomized Controlled Trial Comparative Study
Immunogenicity and reactogenicity of two recombinant hepatitis B vaccines in small infants: a randomized, double-blind comparative study.
Hepatitis B infection is very common in infants, especially in countries with limited resources. Hepatitis B vaccination is recommended in the routine immunization schedules in many countries, including India. We compared immunogenicity and reactogenicity of two recombinant hepatitis B (HB) vaccines in healthy infants. ⋯ Geometric Mean Titer after third dose was 383 mIU/ml and 285 mIU/ml, respectively, also this difference remaining insignificant. Adverse events were similar in both vaccine groups. Immunogenicity and reactogenicity of the Indian and European Hepatitis B vaccines were comparable, when immunization was started at birth.
