Seven-component antigen african swine fever subunit vaccine

An African swine fever virus (ASFV) antigen protein combination, wherein the ASFV antigen protein combination consists of a P34 protein, a P30 protein, a P54 protein, an A104R protein, an X protein, a C129R protein, and a Y protein;

• wherein the X protein is a DP96R protein or a fusion protein of the DP96R protein and a P12 protein;
• and the Y protein is a fusion protein of an extracellular domain of a P22 protein and an extracellular domain of a P17 protein;
• the P34 protein, the P30 protein, the P54 protein, the A104R protein, the X protein, the C129R protein, and the Y protein are in a ratio of (1-6):(1-6):(1-6):(1-6):(1-6):(1-6):(1-6);
