Hungary has developed an effective vaccine for humans to be immune from the H5N1 bird flu virus, Prime Minister Ferenc Gyurcsany announced on Tuesday.

The vaccine was developed by the Hungarian company Omnivest and has been approved by the national pharmaceutical institute (OGYI) for commercial production in Hungary, the PM said.

According to him, the vaccine would be used on people who are working closely to sick birds. However, the vaccine can only fight against the current H5N1 virus in human bodies, but not a mutated form.

At present, the H5N1 bird flu virus is transmissible among birds, but can't be transmitted among humans. However, it's widely feared that the virus would mutate one day and cause a global epidemic.
