African swine fever is re-emerging in Nghe An . Many localities have outbreaks, with large numbers of infected and culled pigs. Vaccination against African swine fever is considered a fundamental solution to prevent the disease, but to date, the vaccination rate is very low.
Specifically, according to statistics from the Provincial Department of Animal Husbandry and Veterinary Medicine, the province currently has over 1 million pigs. However, by the end of December 2023, only 1,258 doses of African swine fever vaccine had been vaccinated for 1,258 pigs aged 4 weeks or older in 4 districts: Yen Thanh 488 pigs, Que Phong 600 pigs, Quy Chau 150 pigs, and Hung Nguyen 20 pigs. Currently, according to assessments, the pigs are growing and developing normally after vaccination.
However, in districts where African swine fever is complicated such as Anh Son, Thanh Chuong, Nghi Loc, Dien Chau... pigs have not been vaccinated with this vaccine.
The reason for the low vaccination rate against African swine fever is that this vaccine is only given to qualified pigs. Specifically, the AVAC ASF LIVE vaccine of AVAC Vietnam Joint Stock Company is used for pigs from 4 weeks of age and older; the NAVET-ASFVAC vaccine of NAVETCO Veterinary Medicine Joint Stock Company is for pigs from 8 to 10 weeks of age; these vaccines are not given to sows and boars.
For large farms that want to vaccinate, they must ensure conditions such as biosafety in animal husbandry, appropriate ages for each type of vaccine, healthy pigs, no clinical signs of infectious diseases...
In addition, the current price of African swine fever vaccine is more than 60,000 VND/dose. People who want to vaccinate their animals will have to pay for it themselves, which is considered a quite high price for livestock farmers.
Ms. Phan Thi Thanh in Dien Nguyen commune, Dien Chau district said: My family has a herd of 11 pigs, if we vaccinate the whole herd, it will cost over 600,000 VND. This is quite a high cost for purely agricultural households like us...
In fact, for households with a total herd of less than 10 animals, it is still acceptable to spend money to vaccinate animals. For households with large numbers of animals such as farms, ranches, with the number of animals up to hundreds, spending a large amount of money on vaccination makes many owners have to consider and calculate carefully.
Nghe An Provincial People's Committee has issued Official Dispatch No. 7296/UBND-NN on "strengthening disease prevention and control and using African swine fever vaccine".
Accordingly, localities shall consider and decide to use African swine fever vaccine to prevent and control the disease in their localities based on the livestock and disease situation in their localities. Strengthen information and propaganda work widely in various forms, with appropriate content and the situation of using African swine fever vaccine so that people are informed.
Select and count livestock farms that need African swine fever vaccination that meet all conditions, compile the list and send it to the Department of Animal Husbandry and Veterinary Medicine to connect with vaccine supply companies in a timely manner.
Please note that during the vaccination process, pigs may have been infected with African swine fever virus and other pathogens, but have not yet shown clinical symptoms. When pigs are vaccinated, they may react, develop illness, die, and must be treated for the outbreak and the diseased pigs must be destroyed according to regulations.
Report the results of using African swine fever vaccine (if any), as well as promptly send a complete and accurate written report of difficulties and problems to the Department of Animal Husbandry and Veterinary Medicine for coordination in handling.
Closely monitor the African swine fever vaccination process at the facility, ensure early detection and timely handling of unexpected risks when using African swine fever vaccine. Coordinate with the Department of Animal Husbandry and Veterinary Medicine to collect samples for evaluation after vaccination.
