Antigen Depot Effect Overview
The "antigen depot effect" refers to a mechanism by which certain vaccine adjuvants enhance immune responses by creating a localized reservoir of antigen at the injection site. This slow release provides prolonged stimulation to the immune system, leading to higher and more persistent antibody titers. While historically considered essential for adjuvant function, recent studies suggest it may not be strictly required for all immune responses.
Mechanism of Action
Prolonged antigen exposure to antigen-presenting cells, leading to enhanced adaptive immune responses.
