1. The plural of antigenicity; the quality or degree to which a substance acts as an antigen and stimulates an immune response.
Usage: technical; immunology

Examples

• The antigenicities of different viral strains vary significantly, affecting vaccine effectiveness.
• Researchers compared the antigenicities of mutant proteins to understand immune recognition.
• The antigenicities of these compounds determine how strongly they trigger antibody production.
• Variations in antigenicities across pathogen variants complicate vaccine development.
• Scientists measured the antigenicities of candidate antigens before clinical trials.
