Three to 4 weeks post-administration of alive variants or inactivated b23, respectively administered via eye drop and subcutaneously, the protection against a challenge was not different from that following La Sota vaccination. Antibody titers induced by a25 and b23, as measured by 2 ELISA blocking tests (the first employing a NDV specific Mab 2114, the second employing Mab 3115), were significantly lower (P less than 0.001) than post-challenge antibody titers. On the contrary, the difference between post-La Sota vaccination antibodies and post challenge antibodies was weak (P less than 0.02). Following 3 successive exposures by contact of chickens to live b23 variant, no variation in antibody titers was observed as measured by ELISA employing Mab 3115.
