The present invention relates to recombinant proteins encoding at least two antigenic epitopes joined by flexible hinge domains. Proteins of this design enable presentation of each epitope to the immune system and are particularly useful as vaccines against infectious agents, such as viruses, when many variants of that agent exist. Moreover, the recombinant proteins of the invention are useful as a single vaccine composition effective against diverse infectious agents since the subject proteins can have antigenic epitopes from different infectious agents. The invention further provides nucleic acids, expression vectors, host cells and methods for production of the subject recombinant proteins as well as vaccines and methods for treating HIV.
A recombinant protein which comprises alternating peptide and spacer domains wherein said protein has an amino acid sequence which comprises SEQ ID NO:8.
An isolated nucleic acid encoding a recombinant protein which comprises alternating peptide and spacer domains wherein said protein has an amino acid sequence which comprises SEQ ID NO:8.
