Article Correctness Is Author's Responsibility: A seven-gene-deleted African swine fever virus is safe and effective vaccine in pigs

(Science China Press) African swine fever (ASF) is severely threatening the global pig industry. An efficacious vaccine is urgently required. Using the Chinese ASFV HLJ/18 as a backbone, Chen and his colleagues generated a series of gene-deleted viruses. The virulence, immunogenicity, safety, and protective efficacy evaluation in specific-pathogen-free pigs, commercial pigs, and pregnant sows indicated that HLJ/18-7GD with seven-gene deletion is a safe and effective vaccine against ASFV.
