WASHINGTON (Reuters) - A bird flu vaccine being developed by San Diego-based Vical Incorporated protects mice and ferrets against the feared H5N1 avian influenza virus, the company said on Tuesday.

It may also offer potential as a "universal" flu vaccine because it targets parts of the virus that all flu strains have, Vical and researchers testing the shot said.

This so-called cross-protection would mean that new vaccines would not have to be formulated every flu season and could provide a chance to stockpile vaccine ahead of a pandemic. [....]

"Achieving cross-protection is the 'Holy Grail' in flu vaccines, and the current studies provide evidence that such a goal may be feasible using a DNA vaccine targeting conserved influenza virus proteins and formulated with our proprietary Vaxfectin adjuvant," said Vijay Samant, president and chief executive officer of Vical.

Experts say that human-to-human transmission of the virus is required for the avian flu to become an epidemic, and there have been few documented cases of human-to-human transmission of the avian flu virus worldwide.
