Current national COVID‐19 vaccination guidelines and recommendations focus vaccine guidance on patients with cancer. In this COVID‐19 vaccination race, “cocoon vaccination” strategies which include informal caregivers and household contacts as priority groups for SARS‐CoV‐2 vaccination could be an additional strategy used to protect patients with cancer who may have limited immune responses to current vaccinations. Medical systems specializing in cancer care should support education and vaccination campaigns which target informal caregivers and household contacts in addition to cancer patients.
