The study involves two GMOs. ChAdOx1-HPV is a recombinant replication-incompetent chimpanzee-derived adenovirus (ChAdY25) viral vector. MVA-HPV is a modified vaccinia virus Ankara vector (MVA). Both vectors encode a fusion of sequences derived from HPV.
Two replication-deficient lymphocytic choriomeningitidis virus (rLCMV) vectors, one expressing a truncated gBprotein of HCMV and one expressing the pp65 protein of the human CMV
