"On Immunity is a book I've recommended too many times to count--a searching, empathetic, ultimately unassailable argument, not just for vaccination but for thoroughly acknowledging our interdependence, and for all that becomes necessary and possible once we do. Written before COVID, it nonetheless speaks directly to the concerns of the pandemic era--to the fact that we are dangerous as well as vulnerable, to the way collective well-being and individual self-interest are configured at odds to one another when they are fundamentally intertwined."--Jia Tolentino
