The f rabies vaccine is characterized by comprising rabies virus inactivated vaccine raw materials and composite adjuvant; the composite adjuvant is composed of zinc hydroxide colloid, cholesterol, mannan oligosaccharide and Tween-80; each dosage of the rabies virus inactivated vaccine raw materials comprises 0.1 mg to 10 mg of zinc hydroxide colloid, 10 micrograms to 1000 micrograms of cholesterol, 10 micrograms to 1000 micrograms of mannan oligosaccharide and 10 micrograms to 1000 micrograms of Tween-80. When the composite adjuvant is adopted, the immune response time is greatly prolonged, neutralization is rapidly generated, the immune duration time is long, the preparation process is simple, required devices are easily obtained, the industrial production cost is greatly reduced, and the stability of the obtained rabies vaccine is greatly improved.
