Immunogenicity

The ability of a substance, such as an antigen or epitope, to provoke an immune response in the body. This response can involve the production of antibodies or the activation of specific immune cells, making it a critical concept in immunology, vaccine development, and therapeutic protein design. Immunogenicity is particularly relevant for researchers and developers in the fields of immunology and biopharmaceuticals, as it determines how the immune system recognizes and responds to foreign substances.
