Epstein-Barr Virus antigen constructs

A nucleic acid comprising:

• (A) a polynucleotide encoding a polypeptide, the polypeptide comprising:
• (a) an Epstein-Barr Virus (EBV) latent membrane protein 1 (LMP1) fragment, the EBV LMP1 fragment comprising one or more of SEQ ID NOs:
• 2-5;
• (b) an EBV latent membrane protein 2 (LMP2) fragment, the EBV LMP2 fragment comprising one or more of SEQ ID NOs:
• 7-10;
• (c) an EBV nuclear antigen 1 (EBNA1) fragment, the EBNA1 fragment comprising at least 8 amino acids of SEQ ID NO:
• 11;
• (d) an EBV nuclear antigen 3A (EBNA3A) fragment, the EBNA3A fragment comprising one or more of SEQ ID NOs:
• 14-20;
• or
• (e) an EBV ZEBRA fragment, the EBV ZEBRA fragment comprising one or both of SEQ ID NO:
• 22 or SEQ ID NO:
• 23;
• wherein the polypeptide is at least 80% identical to SEQ ID NO:
• 24 or SEQ ID NO:
• 26;
• and
• (B) a sequence that is capable of directing expression of the polypeptide in a host cell;
• wherein the polynucleotide is operatively linked to the sequence that is capable of directing expression of said polypeptide in the host cell.
