Bird flu detected in vaccinated Egypt flocks - source

CAIRO (Reuters) - Egypt has detected bird flu in chickens and ducks from reportedly vaccinated flocks in a sign that inoculation procedures in the most populous Arab country may be lacking, an animal health official said on Tuesday. 

The official, who closely follows bird flu in Egypt, said chickens and ducks from vaccinated household flocks and on poultry farms had tested positive for the H5N1 bird flu virus this year in 12 locations, and eight of the infections were detected this month.
