Key Points

Question What is the serologic status and incidence of adverse effects in patients with cancer who are receiving therapy after administration of the SARS-CoV-2 BNT162b2 vaccine?

Findings This cohort study evaluated serologic status and safety of the BNT162b2 vaccine in 232 patients receiving active treatment for cancer and 261 health care workers who served as controls. After the first dose of the vaccine, 29% of the patients were seropositive compared with 84% of the controls; after the second dose, the seropositive rate of the patients reached 86%, and reported adverse events resembled those of healthy individuals.

Meaning The SARS-CoV-2 BNT162b2 vaccine appears to be safe with satisfactory levels of seropositivity in patients undergoing treatment for cancer, although protection may occur later compared with the healthy population.
