A series of videos is guiding students at the University of Wisconsin-Green Bay as it maintains the safest possible environment this semester. The series, created by professor of immunology Brian Merkel, covers a range of topics, including why young people should remain vigilant about the virus, the science of vaccines and the reasons for getting a flu shot. The videos, which are also meant to dispel myths and rumors about the pandemic, appear to be having an impact. The university’s COVID dashboard shows a positivity rate of 0.87%, out of about 5,400 tests since the beginning of September. About 7,600 students are enrolled at the university’s four locations.
