Chinese Ministry of Agriculture announced on October 14, 2005 that the Harbin Veterinary Institute, part of the Chinese Academy of Agricultural Sciences, has developed a recombinant vaccine to fight subtype H5 highly pathogenic strains of bird flu, using Newcastle Diseases Virus (NDV) as the carrier, and internationally advanced anti-gene techniques. As the first of its kind in the word, the new vaccine has the following enhancements:
1) The vaccine can be used to fight both highly pathogenic strains of bird flu, and Newcastle diseases virus in one injection.
2) The vaccine has little side effects on newborns. In addition to injection, it can be applied using other forms, including drinking, spraying, nozzle and eye dripping, which makes it a simple, convenient, and fast vaccination with reliable quality for required efficiency and density.
3) It is desirable for poultry farm sized vaccination. The day-I newborns are allowed to be vaccinated, without compromising the quality of meat.
The low cost can reduce the expenses on vaccination. The new vaccine asks only one fifth of the cost, compared with the vaccine in current use.
