Researchers wrote that until now efforts to develop an all-purpose flu vaccine have been thwarted by the ever-mutating flu virus head, which tricks the body into producing antibodies that are only temporarily effective.
But the lab-created antibodies were able to attack in mice the virus’s hidden non-mutating “neck”, which prevented the virus from multiplying. Researchers have said it will be years before they learn if the antibodies will work in infected humans.
The H5N1 virus emerged in humans in Hong Kong in 1997; of the 408 cases confirmed since, 62 percent resulted in death, according to the World Health Organization as of 24 February.
