Mechanism of action

TT (also known as Convidecia or Ad5-nCoV) uses a replication-incompetent adenovirus serotype 5 as a viral vector to deliver genetic instructions for producing the SARS-CoV-2 spike protein. This triggers both cellular and humoral immune responses, enabling the body to recognize and neutralize the virus upon exposure. The vaccine can be administered as a single dose or in a prime-boost regimen.
