Immunogenicity refers to the ability of an antigen to induce an immune response, directly impacting the safety, efficacy, and protective immunity of a vaccine.

The primary goal of immunogenicity assessment is to ensure that a vaccine can activate a specific immune response, helping individuals establish immune memory against pathogens without triggering adverse reactions or hypersensitivity. This critical step in vaccine development allows researchers to evaluate antigen responses, as well as the strength, type, and role of antibodies, T cells, and other immune responses in immune defense.

We can say, effective immunogenicity assessment is an essential foundation for vaccine development and regulatory approval.
