About Cancer and Flu

Are cancer patients and survivors more likely to get flu than others?

We don't know this specifically. But we do know that cancer may increase your risk of flu complications. People with a weakened immune system due to disease (such as people with HIV or AIDS, or some cancers such as leukemia) or medications (such as those receiving chemotherapy or radiation treatment for cancer) are at increased risk of developing flu complications that can be serious.

Should cancer patients and survivors get a flu shot?

Yes. Influenza vaccines (or flu shots) are approved for use in people with cancer and other health conditions. Flu shots have a long, established safety record in people with cancer.

It is also important for people who live with or care for cancer patients to be vaccinated against seasonal flu. This reduces the risk of getting the cancer patient sick.

Flu shots for older adults

Some older adults (65 years of age and older) may have a weaker immune response to flu vaccines. This can make them more likely to get sick with flu or flu complications even when vaccinated. Certain vaccines are designed to create a stronger immune response in people who are 65 or older.

You may need a pneumococcal shot, too

Having the flu increases a person's risk for pneumococcal disease. Pneumococcal pneumonia is a serious flu-related complication that can cause death. People with cancer or other diseases that compromise the immune system should ask their doctor about a pneumococcal vaccine.

COVID-19 and flu

• Flu vaccines and COVID-19 vaccines can be given at the same time.
• Some of the symptoms of flu and COVID-19 are similar. You'll need a test to determine your illness.
• People with a weakened immune system have a higher risk of getting serious flu complications or getting very sick from COVID-19.
