Evaluation on immuse response of pig stimulated by quadrivalent vaccine against pasteurellosis, salmolnelosis, erysipelas and classical swine fever

Abstract

We have researched and produced successfully the quadrivalent vaccine against four diseases in pig: Pasteurellosis, salmonellosis, erysipelas and classical swine fever. The results of quality control showed that the criteria of the vaccine including purity, safety and efficacy met the base standard and Vietnamese standard (TCVN) for each component of this vaccine. This
is the first study on the quadrivalent, attenuated vaccine for preventing four diseases in pig with only one single injection in Viet Nam. After finishing and delivering to the market, this vaccine will bring many economic benefits to the farmers, marking the success of producing polyvalent vaccine in Viet Nam
