Mustafa Ezat I appreciate your fast response.With a small flock, say 10,000 birds, with 80% protection, 8,000 birds would be protected and 2000 partially or unprotected, provided adequate vaccination coverage is achieved.These 2000 birds would be leading to the generation of new antigenic variants, this is the risk of not using homologous strains.
