Inject vaccinations arbitrarily and expand the target group

Immediately after it was reported that pigs injected with the African swine fever vaccine NAVET-ASFVAC manufactured by Navetco Company, in the days of 23 up The delegation, along with agencies of Binh Dinh Province and Navetco Company, went to 3 Tay Son, Tuy Phuoc, An Nhon in Binh Dinh Province and Phu Yen Province to verify and clarify the cause.

Accordingly, in Binh Dinh Province, with the controlled use of vaccines, the guidance of the Veterinary Authority under the direction of the Ministry of Agriculture and Rural Development, and the guidance of the Ministry of Animal Health, a total of 905 doses of vaccine have been administered to slaughter pigs.

However, based on the information that the use of 905 doses of NAVET-ASFVAC vaccine against African swine fever is effective and in view of the possible outbreak of African swine fever in Binh Dinh, farmers and veterinarians have proposed to stock up on self-vaccination vaccines for all pig species (sows, boars, piglets and piglets) with a total of 4,950 doses.

According to the Ministry of Agriculture and Rural Development, the expanded injection, the uncontrolled use of vaccines and the instructions of the veterinary bureau are not in line with the instructions of the ministry, as well as the instructions of the ministry of animal health.

Then, 542 (89%) pigs responded after vaccination, of which 297 died (49%); 245 animals are treated for symptoms and are recovering. The Department of Animal Health delegation will continue to coordinate with local authorities to assess the situation, guide and support responses to address emerging issues, and prevent and control disease.
