In today’s episode, Tim Suther is joined by Dr. Mark Cullen, who’s been at the forefront of population health for decades—even before it was a recognized field. Listen in as Tim and Dr. Cullen discuss the collaborative effort that has gone into the COVID-19 Research Database, and what the resulting research and analysis can tell us about vaccine effectiveness, breakthrough infections, social determinants of health (SDoH), and booster vaccines. Today’s panel includes: Dr. Mark Cullen, consultant in population health and the Founding Director of the Stanford Center for Population Health Sciences; and Tim Suther, senior vice president, data solutions at Change Healthcare. Here’s what they chatted about: What data can tell us about COVID-19 vaccine effectiveness and breakthroughs, and what it can’t. What’s behind vaccine hesitancy and where we go from here. How social determinants of health (SDoH) and pre-existing conditions have affected infection and mortality rates.
