PROBLEM TO BE SOLVED: To provide a vaccine composition for the prevention of mystery swine disease by using ATC-VR 2332 virus of swine hyperplasia and respiratory syndrome as a component. SOLUTION: This vaccine contains ATCC-VR 2332 virus of swine hyperplasia and respiratory syndrome modified to be non-pathogenic to pigs together with a carrier for the virus. A pig is immunized against swine hyperplasia and respiratory syndrome (abbreviated as SIRS or mystery swine disease) by administering the vaccine composition to a pig. SIRS is an infectious disease including sterility, respiratory disease, dysorexia, pyrexia, dyspnea and light neurological symptom. ATCC-VR 2332 virus is an intractable RNA virus having non-blood coagulating envelope and proliferating in the kidney of a monkey and cell line of other monkeys.
