David Fraser, M.D., an epidemiologist and member of Newtown Quaker Meeting will speak via Zoom on “COVID-19: The Epidemiological Basis of Health Policy” to Newtown Friends Meeting adult class at 9:45 a.m. on First Day (Sunday), Sept. 20.
Fraser will focus on aspects of the science that are often under-appreciated: Bayes theorem, signal theory (based on WWII weapons research), immunity, and effectiveness of masks. The discussion period is also expected to cover such matters as: reopening schools, vaccine trials, antigen testing, and aspects of the national response to the virus.
