In the early spring of 2020, the labs were closed because of Covid metastasizing through New York and the world. I was seeing limited numbers of patients in the hospital—partly because, yet unvaccinated (the vaccines were yet to be approved), I feared transmitting an infection to my chemotherapy-receiving patients whose immune systems could not battle a lethal virus. I still tended to the sickest, the most vulnerable. The oncology wing of the hospital went on heroically, kept alive by nurses.
