At this time, there are three COVID-19 vaccines authorized and recommended in the United States: the Pfizer-BioNTech, Moderna, and Johnson & Johnson/Janssen vaccines. These vaccines are described on the US CDC’s vaccine page.
The American Society of Hematology (ASH) has also released relevant information in “Immune Thrombotic Thrombocytopenia: Frequently Asked Questions.”
Memorial Sloan Kettering Cancer Center has made available an interim guideline on vaccination for cancer patients. The National Comprehensive Cancer Network (NCCN) has made available preliminary recommendations as well. The recommendations in these documents are based on opinion and extrapolation from other vaccine studies and may change rapidly as new information becomes available.
Should people with cancer be vaccinated against COVID-19?
At this time, patients with cancer may be offered vaccination against COVID-19 as long as components of that vaccine are not contraindicated. The current Centers for Disease Control and Prevention (CDC) interim clinical guidance discusses immunocompromised individuals. It states: “Immunocompromised individuals may still receive COVID-19 vaccination if they have no contraindications to vaccination. However, they should be counseled about the unknown vaccine safety profile and effectiveness in immunocompromised populations, as well as the potential for reduced immune responses and the need to continue to follow all current guidance to protect themselves against COVID-19.” The expert panel noted that while some immunocompromised patients may experience decreased response to the vaccine, it may still confer some benefit and is important to reduce the risk or severity of COVID-19 to cancer patients, especially given recent evidence of higher rates of severe infection.
Should people undergoing active treatment for cancer be vaccinated against COVID-19?
At this time, patients undergoing treatment may be offered vaccination against COVID-19 as long as any components of the vaccine are not contraindicated. Oncologists have experience providing other types of vaccines to patients receiving treatment for cancer, including chemotherapy, immunotherapy, radiation therapy or stem cell transplantation. Strategies such as providing the vaccine in between cycles of therapy and after appropriate waiting periods for patients receiving stem cell transplants and immune globulin treatment can be used to reduce the risks while maintaining the efficacy of vaccination. ASCO is only aware of one study published to date, Wassengrin et al, Lancet Oncol, that has specifically reported on vaccine safety outcomes in patients with cancer receiving treatment (immune checkpoint inhibitors).
Should cancer survivors be vaccinated against COVID-19?
Cancer survivors may be offered vaccination against COVID-19 as long as any components of the vaccine are not contraindicated.
Are there people who should not be vaccinated?
At this time, only those with contraindications to a specific vaccine component should not be offered vaccination with that specific product. These contraindications are described in detail in CDC interim clinical guidance.
What other concerns are there for people with cancer who are vaccinated?
As there is still uncertainty around the extent to which immunocompromised patients with cancer will develop immunity in response to vaccination, vaccinated patients should continue to follow current guidance to protect themselves from exposure to COVID-19. The expert panel underscored the message that while providing the vaccine to cancer patients and their caregivers will reduce the risk for infection or clinical COVID-19 disease, they emphasized the importance of continuing practices of wearing masks, social distancing, and maintaining good hand hygiene even after vaccination.
There have been reports that patients with both solid tumors (Palich et al, Ann Oncol; Shroff et al, medRxiv; Addeo et al, Cancer Cell) and hematological malignancies (Roeker et al, Leukemia; Herishanu et al, Blood; Terpos et al, Blood) may have a weaker response to both first and second vaccine doses, most notable in those with hematologic malignancies, those receiving rituximab, and those actively receiving immunotherapy, chemotherapy, and select targeted therapies. These reports include small numbers of patients and therefore the evidence is still developing. At this time, ASCO recommends that patients with cancer be vaccinated according to the same guidelines as all other individuals. However, as further evidence becomes available, alternative vaccination procedures (e.g. with immunity testing, third dose) may become relevant.
There is some evidence that vaccination with mRNA vaccines prior to imaging may cause difficulties in interpretation of the resulting images. Two multidisciplinary groups have published information on imaging in general in the context of COVID-19 vaccination: Lehman et al, J Am Coll Radiol; Becker et al, Radiology. The Society for Breast Imaging has published guidance on how these potential difficulties should be managed in patients with breast cancer.
The COVID-19 and Cancer Clinical Trials Working Group has published information on vaccination of patients who are seeking to participate in or enrolled in clinical trials (Desai et al, Nat Rev Clin Oncol).
CDC Advisory Committee on Immunization Practices
CDC is regularly updating the number of vaccines distributed and administered on their COVID-19 page. ACIP continues to convene emergency meetings as new information, evidence and clinical trial results are available. Materials from previous meetings and suggested dates and agendas for future meetings can be found on the CDC website.
HHS Expands Pool of Professionals Eligible to Administer COVID-19 Vaccines
On January 28, 2021, HHS added additional categories of qualified persons authorized to prescribe, dispense, and administer COVID-19 vaccines authorized by the FDA. This action authorizes any healthcare provider who is licensed or certified in a state to prescribe, dispense, and/or administer COVID-19 vaccines in any other state or US territory. It also authorizes any physician, registered nurse, or practical nurse whose license or certification expired within the past five years to prescribe, dispense and/or administer COVID-19 vaccines in any state or US territory so long as the license or certification was active and in good standing prior to the date it went inactive.
Please see this announcement for additional information, including training requirements and details on liability protections.

Resources from the Centers for Medicare and Medicaid Services
The Centers for Medicare and Medicaid Services (CMS) COVID-19 page includes valuable information on coverage and reimbursement for vaccine administration. CMS’ Office of Minority Health (CMS OMH) has also developed a COVID-19 Vaccine Resources website of federal resources and organized them for health care professionals, partners, consumers, and for assistance in additional languages.
