antigenic
Triggering immune response
Antigenic describes something capable of triggering an immune response—specifically, the production of antibodies.
Viruses, bacteria, and foreign proteins are antigenic; the immune system recognizes them as invaders.
The antigenic properties of the vaccine stimulate immunity without causing disease.
Antigenic drift and antigenic shift describe how pathogens evolve to evade immune defenses.
