Mr. Schaefer took a public stand against the errors of Alberta’s Medical Director: Dr. Deena Hinshaw’s recommendation of N95, Procedural and Nonmedical masks as protection from the coronavirus know as COVID-19.
His four page open letter penned to Dr. Hinshaw in June 2020 once published was shared by millions on social medias and by independent media outlets around the world. Even today it is the definitive document detailing the limitation and hazard potential of the masks recommended and later mandated as protection from COVID-19.
Since then Mr. Schaefer has created numerous resources for the public to read and share to end the harmful practice of cloth/paper covers over mouth and nose.
