More than five years since the start of COVID-19, the virus is still here — evolving, spreading, and leaving lasting impacts. In this episode of Infectious Dose, Heather—a virologist-turned-science writer—examines the costs of the erosion of protective messaging, what new data say about reinfection, and the risks of losing vaccine access under a shifting political landscape. From airborne transmission to long COVID, this episode unpacks the real-time consequences of disinformation, underreaction, and systemic neglect.
Because the pandemic isn’t over—we’ve just stopped talking about it.
