African swine fever is a highly contagious disease caused by African swine fever virus (ASFV), which has caused serious economic losses to the pig industry. Since 192 1 first discovered African swine fever in Kenya, many scientific research institutions and companies around the world have been working hard to develop African swine fever vaccine.
Although some progress has been made, there is no commercial African swine fever vaccine at present. Some advances include:
At 1. 20 19, a Russian company announced the successful development of African swine fever vaccine, and has started clinical trials in the local area. However, the safety and effectiveness of this vaccine have not been widely recognized internationally.
2. Paizhi Bio-company in China is also working on the research and development of African swine fever vaccine. It is reported that the company's vaccine has entered the clinical trial stage and achieved positive test results in some areas. However, the final commercialization and promotion of the vaccine may take some time.
3. Many other scientific research institutions and companies around the world are also actively studying African swine fever vaccine, but there is no completely successful commercial vaccine at present.
In short, the research and development of African swine fever vaccine is still a challenge, but some progress has been made. Finally, we need to wait for the vaccine to undergo strict safety and effectiveness tests before we can determine its application in pig industry.
