Two New N5 Subtype
Bird Flu Vaccines Were Successfully Developed
Organized by both the Ministry of Agriculture
and the Ministry of Science and Technology of China and funded by
National ¡°973¡± and ¡°863¡± Programs, a new H5N1 subtype bird flu killed
vaccine and avian live fowl pox virus vector-based vaccine, which
possesses international advanced level with high efficacy and safety,
were successfully developed recently by more than 30 experts in
Animal Flu Key Opened Laboratory in the Institute of Harbin Veterinary
Medicine, Chinese Academy of Agricultural Sciences and National
Bird Flu Reference Laboratory.
The new H5 subtype bird flu killed vaccine was prepared from the
strain of highly attenuated H5N1 subtype vaccine, using international
advanced construction strategy of bird flu vaccine strain¡ªgene reverse
handling for flu virus and its surface gene deciding immunity protection
was from epidemic high pathogenic strain of bird flu and artificially
lose the gene group deciding high pathogen series of bird flu virus.
The vaccine is not only safe to mammals, but also to poultries.
H5 subtype bird flue recombined fowl pox vaccine was a new type
gene engineering bird flue and fowl pox vaccine constructed with
high mature and safe fowl pox virus as vector, which is a highly
specific with immunity period 6~10 months, with great superiority
compared with that of same vaccine in the world now. The vaccine
is characterized with high efficiency, safety and low cost and convenient
for epidemic monitoring.
