immunogenicity

Immunogenicity refers to the ability of a substance, such as a vaccine or foreign protein, to provoke an immune response in the body. This means that when the immune system encounters the substance, it recognizes it as a threat and activates defenses, producing antibodies and other immune cells. The higher the immunogenicity, the stronger the immune response, which can help the body identify and fight off actual infections in the future. Understanding immunogenicity is crucial for developing effective vaccines and therapies to protect against diseases.
