August is National Immunization Awareness Month, a time to highlight the important role vaccines play in protecting people of all ages from preventable diseases. For people with cancer, staying up to date on recommended immunizations can be especially important, as some cancer treatments may weaken the immune system and make it harder to fight off infections. Before receiving any vaccine, it's important to talk with your oncology team about which immunizations are right for you and when they should be given.  

Why Vaccines Are Important for Cancer Patients 

Cancer and certain treatments, such as chemotherapy or radiation therapy, can affect the body's immune system. This may increase the risk of developing serious complications from illnesses that could otherwise be prevented through vaccination. While vaccines may not provide the same level of protection for everyone receiving cancer treatment, they can still help lower the risk of severe illness and hospitalization. Your healthcare team can help determine which vaccines are appropriate based on your diagnosis and treatment plan.  

Which Vaccines May Be Recommended? 

The vaccines recommended for people with cancer vary depending on their age, medical history, and treatment schedule. Many patients are encouraged to stay up to date on recommended immunizations, which may include: 

• An annual flu vaccine  

• Pneumococcal vaccines to help protect against certain types of pneumonia  

• The shingles vaccine for eligible adults  

Some vaccines, particularly those that contain live viruses, may not be recommended during certain types of cancer treatment. That's why it's important not to schedule immunizations without first discussing them with your oncology provider. 

Timing Matters 

Knowing when to receive a vaccine can be just as important as receiving it. In some cases, your care team may recommend getting vaccinated before treatment begins, while others may be best given during a specific point in your treatment or recovery. Every patient's situation is different, and your oncology team will help determine the safest and most effective timing for your recommended immunizations.  

Talk With Your Care Team 

Vaccines are one of many tools that can help protect your health during and after cancer treatment. If you have questions about vaccines, bring them up at your next appointment. Your oncology provider can help you decide which immunizations are recommended and when they should be given.
