The study involves a replication-incompetent adeno-associated virus, AAV9, lacking all AAV viral genes and encoding for the human Progranulin (GRN) gene
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).
Genes of the human Parainfluenza virus fusion (F) and hemagglutinin-neuraminidase (HN) proteins; gene of the human Respiratory syncitial virus fusion protein (RSV F).
