Intervention: ChAdV68-S
Description: Chimpanzee Adenovirus serotype 68 - Spike (ChAdV68-S) is a replication-defective, E1, E3 E4Orf2-4 deleted adenoviral vector based on chimpanzee adenovirus 68 (C68, 68/SAdV-25, originally designated as Pan 9), which belongs to the sub-group E adenovirus family. A single 0.5 mL intramuscular injection will be administered in the deltoid muscle. When possible, the prime vaccine and boost vaccine should be administered in different arms.
