COVID vaccine: Information for people on active cancer treatment

People with cancer* should get vaccinated against COVID-19 unless specifically advised otherwise by their medical team. The Joint Committee on Vaccination and Immunisation (JCVI), the expert group that advises on vaccinations policy, recommends that people on active cancer treatment get vaccinated.

They also make recommendations about the timing of each dose of vaccine in relation to your cancer treatment.

You may be approached about receiving a COVID vaccine at the same time as the flu vaccine. This is acceptable - flu and COVID vaccines are frequently given together.

Your specialist cancer team will be happy to discuss COVID-19 vaccination with you and answer any questions you may have.

Further information on COVID-19 vaccination is available in the Vaccination section of the NHS website.

*Excluding bone marrow/stem cell transplant patients (BMT patients). BMT patients should follow their own vaccination schedule as advised by their medical team.

About the vaccines

COVID vaccines are NOT live vaccines and cannot cause disease. That means they are safe for people undergoing cancer treatment and anyone with a weakened immune system.

It is possible that people with a weakened immune system may not develop as strong an immune response (immunity) when vaccinated but the potential benefits of being vaccinated are still significant.

If you are a patient who has an allergy to polyethylene glycol (PEG) then you should tell your vaccinator and will receive the AstraZeneca vaccine as a booster as well.

We would advise patients to get vaccinated unless advised otherwise by their medical team but:

  • Not to get vaccinated on the same day as receiving most systemic anti-cancer therapy e.g. chemotherapy or immunotherapy. This does not apply to patients who are only having radiotherapy. People on daily tablet treatment can also be vaccinated the same day.
  • Not to get vaccinated while being treated for an infection.
  • Not to get vaccinated if feeling very unwell due to side-effects from systemic anti-cancer therapy.
  • Not to get vaccinated in the week before planned surgery and to wait until fully recovered after being discharged.
  • If you are on chemotherapy the recommended time to receive the vaccination is the week prior to your next dose of treatment (2-3 weeks after your last chemotherapy treatment)

For more information

If you have any further questions about COVID-19 vaccines in relation to your cancer treatment, speak to your clinical team. Please do not call our Patient Hotline as this blocks the line for people who need urgent medical advice. We have produced this guide with information about COVID, flu and pneumococcal vaccines if you are undergoing cancer treatment.
