Take As Directed

Chris Murray kindly returned to the podcast for another round. We know now that variants increase transmissibility “by quite a bit,” and have the potential to increase the fatality rate and escape vaccines, lowering efficacy rates. The Novavax trial, ominously, showed that one variant can reinfect individuals previously infected. It’s a new, uncertain world in which SAR-COV-2 is not overcome and eliminated, but rather becomes endemic, a “seasonal flu only ten times worse.” We know that accelerating vaccination campaigns, with excellent vaccines, combined with seasonality (end of winter, arrival of summer) can drive the pandemic down.
