Swine Fever Vaccine Risks and Trade Concerns

World animal health body warns of swine fever vaccine risks as Vietnam readies exports. The World Organisation for Animal Health (WOAH) is cautioning against the use of African swine fever (ASF) vaccines due to concerns about insufficient data sharing and safety. Vietnam has authorized two attenuated live-virus vaccines against ASF, leading to global concern and potential trade restrictions. The vaccine developed by AVAC Vietnam JSC is being scrutinized for its safety and effectiveness, with the USDA also developing vaccines but none having obtained commercial approval. The WOAH is discussing a new global standard for evaluating ASF vaccines, which could lead to trade restrictions on pork-exporting countries.
