Tonight, the Perpetual Notion Machine has aired an edited version from a previous episode of the WORT daily afternoon program A Public Affair. PNM has done a fair number of its own episodes concerning the COVID-19 pandemic. But on Dec. 1, 2020, host Carousel Bayrd talked with Dave O’Connor about what we have learned about the coronavirus in the last 6 to 8 months, what soon-to-be released vaccines will consist of, and whether developing a vaccine too soon might be safe. Dave works in the Department of Pathology and Laboratory Medicine in the UW-Madison School of Medicine and Public Health. He has several areas of research, the primary focus being, until Sars CoV-2, HIV/AIDS pathogenesis. But this previous research knowledge has helped him understand some similarities the coronavirus has with HIV.
