Chinese scientists have developed and tested a new type of
vaccine to guard against the H5N1 bird flu virus, according to
reports on Saturday.
The vaccine, developed jointly by the Ministry of Agriculture
and Ministry of Science and
Technology, will keep chickens, ducks and geese immune for
over 10 months after being injected, four months longer than
existing immunizations.
The Ministry of Agriculture has instructed local authorities to
ensure wide use of the vaccine.
Ducks and geese are believed to be the major hosts of the fatal
avian influenza.
