Pre-existing immunity protects against airborne spread of flu viruses

Caption

University of Pittsburgh School of Medicine virologists conducted an experiment to learn about the transmission of pandemic diseases, like influenza and COVID-19. Through experiments in ferrets that mimic real world conditions for humans, they shed more light on how proximity, masks or other barriers, time spent with someone who is infectious, and pre-existing immunity from vaccines or prior infection may influence the likelihood of someone contracting a virus.
