The continuing spread of African swine fever (ASF) is a global concern for the pig industry, as no region is left unaffected. For many years, the lack of a vaccine or effective treatment has made it very difficult to control the disease. The research community has been working to develop an effective vaccine, and recent announcements of modified live vaccines being approved or tested in some countries have raised hopes for the availability of new effective tools to contain the current ASF epidemic. Many countries are interested in using these candidate vaccines to help control ongoing outbreaks on their territory.
