Vaccine Potency

**Definition:** The relationship between an elicited ADAPTIVE IMMUNE RESPONSE and the dose of the vaccine administered. It is typically measured in an assay to ensure proper dosing and storage of vaccines whereas VACCINE EFFICACY determines disease risk reduction attributable to vaccination under ideal conditions such as a clinical trial and vaccine immunogenicity measures vaccine's ability to induce an immune response in a vaccinated individual in observational studies setting.
