Addressing the need for urgent and timely information on COVID-19 vaccinations and patients with cancer, ESMO recommends to:
Vaccinate all cancer patients in line with the WHO principles and objectives aiming to reduce deaths and disease burden. Patients with active disease or receiving anticancer treatment deserve an additional priority in case of limitations only.
Diligently collect data via suitable studies and registries, to monitor the effects of vaccines in the vulnerable population, including patients with cancer and their immune response.
Educate and instill confidence among the public and patients in receiving the vaccines and provide them with up-to-date information in lay language.
