From: The vaccination threshold for SARS-CoV-2 depends on the indoor setting and room ventilation
Minimum quanta emission rates (ERq) for Revent ≥ 1.0 for the prison scenario under natural ventilation, mechanical ventilation, and high air quality ventilation conditions as a function of the number of susceptibles. Points #1 and #2 identify the minimum emission rates for high air quality ventilation and natural ventilation at their respective threshold number of susceptibles from Fig. 1C. Point #3 identifies the minimum emission rate for high air quality ventilation at the natural ventilation threshold number of susceptibles, representing both high ventilation and high vaccination. The minimum emission values are labeled in parenthesis, denoting the emission in quanta h−1 and its corresponding percentile in the resting, oral breathing ERq distribution
