Abstract

    Bird flu vaccine from H5N1 strain of avian influenza virus was prepared with two concentrations of adjuvant (Montanide ISA 70MVG). Two vaccines (I and II) were prepared containing 50 and 60% Montanide, respectively. Immune response of both the vaccines as single, as well as booster, dose was evaluated in layer birds through haemagglutination inhibition test. Single dose of both vaccines showed poor immune response, while booster dose gave better response with both the vaccines. However, the vaccine prepared with 60% Montanide provided better immune response compared with the vaccine containing 50% montanide.

Key words: Birdflu vaccine, HI titre, H5N1 avian influenza virus,oil based vaccine.
