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.
Recombinant Vesicular Stomatitis Virus (rVSV) in which the gene encoding for the VSV glycoprotein G has been deleted and replaced with the gene encoding the Zaire Ebola virus (ZEBOV) glycoprotein (GP).
Genetic modifications of the nOPV2 vaccine candidates aimed at stabilizing the genetic sequence against reversion compared to the Sabin-2 strain, nOPV2 candidate 1 (S2/cre5/S15domV/rec1/hifi3), nOPV2 candidate 2 (S2/S15domV/CpG40)
