Homologous … WebRapid change in circulating flu viruses is known as antigenic shift. Shift can happen in several ways: when a flu strain jumps to a species which it has never before infected, or when the process of viral reproduction creates a novel strain. In either case, the human immune system perceives the strain as unfamiliar.
