The invention relates to a
multivalent vaccine, in particular to a chimera
multivalent vaccine based on Ercovirus type 11, 18 and 30 key epitopes as well as a preparation method and application of the chimera
multivalent vaccine. According to the invention, a chimera multivalent vaccine VP1-III is also designed based on key epitopes, an E11-VP1 sequence is taken as a basis, one E18-VP1 key
epitope and two E30-VP1 key epitopes are respectively inserted into the E11-VP1 sequence to obtain a chimera multivalent
protein vaccine VP1-III, and the chimera multivalent
protein vaccine VP1-III is taken as an
immunogen to immunize a mouse to detect
antibody titer and
virus neutralizing capacity of
antiserum. A new thought is provided for designing and preparing multivalent vaccines and detecting
immunogenicity of viral vaccines.
