New research shows how the immune system reacts to a new virus and its emerging variants. Although SARS-CoV-2 is no longer a stranger to the immune system, new virus variants still pose a challenge, according to a working group led by Florian Klein, MD, MSc, the director of the Institute of Virology at the University of Cologne, in Germany.
