Claims22
A vaccine comprising a nucleic acid molecule which encodes a fusion protein, wherein the fusion protein comprises:
- a. a first polypeptide segment comprising at least amino acids 1-240 of a mature Herpes simplex virus (HSV) glycoprotein D, wherein the first polypeptide segment does not comprise a full length mature glycoprotein D;
- b. a second polypeptide segment comprising at least one antigen, wherein the at least one antigen is not an HSV glycoprotein D antigen, wherein the N terminus of the second polypeptide segment is linked to the C terminus of the first polypeptide segment;
- and
- c. a third polypeptide segment comprising a C terminal portion of the HSV glycoprotein D, wherein the N terminus of the third polypeptide segment is linked to the C terminus of the second polypeptide segment.
