six month ten Chinese Academy of Agricultural Sciences 2017-2020 According to the press conference on major scientific research progress in, the environmental release and clinical trials of African swine fever vaccine independently developed by Harbin Veterinary Institute are progressing smoothly.

 

After the outbreak of African swine fever in China, according to the unified deployment of the Party group of the Ministry of agriculture and rural areas, the Chinese Academy of Agricultural Sciences fully organized the scientific and technological research on the prevention and control of African swine fever, and successively completed the laboratory research and industrial intermediate trial production of African swine fever vaccine. A gene deleted vaccine showed good safety and effectiveness. The vaccine strain was isolated from two thousand and nineteen year twelve The environmental release test was approved by the state in March; two thousand and twenty year three It was approved by the Ministry of agriculture and rural areas for clinical trials of veterinary biological products in January, and was approved to carry out clinical trials in Heilongjiang, Xinjiang and Henan breeding bases. Harbin Institute of veterinary medicine, in accordance with the approved experimental program, carried out scientific and rigorous progress, and achieved preliminary results.

 

The environmental release test was carried out smoothly. The team overcame the adverse factors such as local extreme low temperature and new coronal pneumonia three The environmental release test of vaccine strains was started in January. Up to now, the growth status of vaccinated piglets is good without abnormal clinical conditions; the vaccinated sows are in good condition without abnormal clinical manifestations, abnormal estrus and abortion. There was no discharge of vaccine virus and no horizontal transmission in immunized pigs. There was no significant difference between the immunized group and the control group.

 

Clinical trials are progressing well.

Up to now, safety: the immune piglets grew well without obvious clinical adverse reactions; the pigs injected with vaccine were dissected without obvious pathological changes; there was no vaccine virus emission; there was no horizontal transmission; the overall mortality rate was lower than that after immunization 1% There was no significant difference between the immunized group and the control group. Clinical efficacy trials are in progress.

 

In the next step, the Chinese Academy of Agricultural Sciences will implement the unified deployment of the Ministry of agriculture and rural areas on the scientific research and research of African swine fever prevention and control, and accelerate the work of vaccine research and development in accordance with the requirements of animal vaccine biosafety management and veterinary drug evaluation.
