Bird Flu Vaccine
Bird flu or avian influenza is strain of influenza viruses which is caused by viruses adapted to birds. H5N1 is a subtype of the avian influenza virus. This subtype has been a cause of concern over the recent years. It is a potential pandemic threat which has claimed more than a total of 200 lives from different countries.
The concern lies with the possible mutation of the H5N1 with human flu viruses which is potentially fatal because it would be able to spread earlier and could become more deadly than the current strains present.
A vaccine is now developed for bird flu coming from the human strain but this is not yet available commercially.
