[Correlation between the NIH test and the seroneutralizing antibodies obtained after vaccination in the dog]

This work reports on two distinct studies on the analysis of correlation of results of potency tests of rabies vaccine intended for dogs. In a first study, the analysis compares the results of the conventional NIH test in mice with seroneutralizing antibodies obtained after 21 days of vaccination in dogs. Arithmetical analysis (109 NIH results, 466 antibody titres) did not reveal significant linear correlation between the results. In a second study, the analysis compares the results of the conventional NIH test and of the NIH test without booster in mice with seroneutralizing antibodies obtained after 21 days of vaccination in dogs. Arithmetical analysis (27 conventional NIH results (without booster), 118 antibody titres) did not reveal any significant linear correlation between the results.
