摘要: The present invention relates to: a virus vector, which can effectively transfer a macromolecular antigenic peptide into target cells while maintaining a three-dimensional structure that is required for functioning as an antigen; and a vaccine utilizing the vector. Specifically, disclosed are: a virus vector, in which a nucleic acid encoding an antigenic polypeptide is integrated immediately 5' upstream of HN gene of an F gene-defective Paramyxoviridae virus gene, wherein the antigenic polypeptide is expressed as a fusion protein of 130 or more amino acid residues, fused with a TM sequence and/or a CT sequence derived from the virus.
