Vaccine therapy

When harmful invaders like viruses or bacteria enter the body, the immune system takes action to stop them. However, the body doesn’t naturally recognize cancer cells as a threat, so no immune response is triggered. Cancer vaccines are a type of immunotherapy that teaches the immune system to identify and eliminate cancer cells. At Penn Medicine, our medical oncologists are recognized for their expertise in using vaccines to boost the immune system as part of cancer treatment.

Vaccine therapy is not appropriate for all diseases or cancer types. Your doctor will review your medical history to determine which cancer treatments are best for you. At Penn Medicine, we use vaccine therapy to treat:

• Breast cancer 
• Lymphoma 
• Lung cancer 
• Melanoma 
• Mesothelioma 
• Ovarian cancer 
• Prostate cancer

Cancer vaccines are typically administered through injection, like other vaccines. The number of doses required for each cancer vaccine varies depending on the vaccine type and the specific cancer. Some vaccines only need to be administered once, while others may require multiple doses over weeks, months, or years. Your care team will provide you with detailed instructions to ensure you are well informed and know what to expect before your treatment starts.

Recovering after receiving a cancer vaccine can be a unique experience for each patient, with side effects that vary depending on the specific vaccine and your individual health. Some common reactions to immunization for cancer include:

• Redness or swelling at the injection site
• Fatigue
• Fever
• Muscle aches

It’s important to communicate openly with your care team about any discomfort you experience, as they can offer strategies to help ease your symptoms. Taking time to rest, staying hydrated, and finding support from loved ones can also make the recovery process smoother and more manageable.
