Dr. Björn Olsen is a Professor of Infection Medicine at the Department of Medical Sciences, Uppsala University in Sweden. He was an active participant in the public policy debate where Sweden chose to disregard the advice and recommendations of the global scientific community and pursue a separate strategy that led to many unnecessary deaths. As a critic of the Swedish strategy, Olsen experienced hostility from the media and the Swedish Public Health Authority, and he reflects on the relationship between science, political power, and public policy debates.
