According to an article published in the November issue of the Journal of General Virology, a newly invented single vaccine could be used to protect chickens, cats and humans against deadly flu pandemics,
scientists have observed that, H5N1 virus has an unusual expanded host range, not only birds and humans have been infected but also cats, which are usually resistant to influenza. Hence they tried to make a ideal vaccine that could be used in multiple animal species.
This vaccine not only protects birds and mammals against different flu strains but can even be given to birds while they are still in their eggs, allowing the mass vaccination of wild birds.
scientists assured that vaccinating eggs against influenza, would protect wild bird species as well as domestic chickens against pandemic flu strains, it will also limit the spread of disease to humans.
