Under the guidance of the Ministry of Agriculture and the Ministry of Science and Technology, the internationally advanced and new and highly effective recombined bird virus vaccine (H5N1 Sub-Type) and bird flu reorganized pox virus carrier vaccine were researched and developed successfully by the Agriculture Ministry's Key Animal Flu open laboratories.

Recently, these two vaccines obtained the approval of the Agriculture ministry's Animal Medicine Evaluation Committee and was awarded the new animal medicine certificate by the Ministry. Compared with the original vaccine, the recombined bird virus vaccine (H5N1 Sub-Type) has a stronger antigen punch and a longer effective immune protection period, which can realize effective immunological protection for ducks, geese, and other poultry. Laboratory studies showed that the new vaccine can remain effective in the chicken's immune system for as long as 10 months, at least 4 months longer than the existing vaccine.
