Avian flu vaccine for California condors approved amid fears of extinction

Vaccine gets emergency approval as ‘highly contagious’ virus sweeps through flocks of species on the brink of extinction

A new vaccine has been granted emergency approval to protect California condors from a deadly strain of avian influenza, federal officials said this week, amid attempts to pull the endangered species back from the brink of extinction.

The emergency action underscores an outbreak that has alarmed the conservation community, who fear that condors, a vulnerable species that has spent decades in recovery, could be dealt a devastating blow. After first being detected in a deceased condor in late March, the illness has swept through the small flock of wild birds, which are closely monitored by agencies in the south-west. So far 21 condors have died, impacting eight breeding pairs, according to a statement issued by the US Fish and Wildlife service.
