I can't get the latest information in real time, but I can give you some general information about African swine fever vaccine research.

African Swine Fever (ASF) is a highly contagious disease caused by African Swine Fever Virus (ASFV), which has caused serious economic losses to the pig industry. Since African swine fever was first discovered in Kenya in 1921, 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. Part of the progress includes:

1. In 219, a Russian company announced that it had successfully developed an 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 not a completely successful commercial vaccine yet.

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 the pig industry.
