Why it is our responsibility to speak out for a universal vaccination mandate.

Patients with cancer are among the most likely to suffer life-threatening complications should they contract coronavirus disease 2019, yet despite encouragement from their oncologists, many continue to refuse to be vaccinated. On behalf of our patients, I believe that oncologists should now exhort our elected government to fulfill its most fundamental responsibility-protecting Americans from existential threats-by enacting either an emergency executive order or universal vaccination legislation and then by helping the rest of the world to vaccinate without delay.
