Japanese researchers develop all-round flu vaccine:

The research team has tested the vaccine on mice implanted with human genes, confirming that it works even if flu viruses mutate, according to Tetsuya Uchida, researcher at the National Institute of Infectious Diseases.

Currently flu vaccines use a protein covering the surface of viruses but the protein frequently mutates to make the vaccines ineffective.

The newly developed vaccine is based on common types of protein inside the bodies of flu viruses as they rarely change, Uchida told AFP. The viruses used are the Soviet-A and Hongkong-A along with the deadly H5N1 strain of bird flu.
