For Patients on Cancer Treatment

Risk to Cancer Patients

If you are getting treatment for cancer, your immune system may be weaker than usual. This means it’s harder for your body to fight off infections like measles, and you could get sicker than other people.

The Measles, Mumps, and Rubella (MMR) vaccine helps protect you from getting measles. It has a very weak form of the virus that won’t make you sick. Instead, it teaches your body how to fight the real virus if you come into contact with it.

Symptoms & Exposure

If you have any of the following, contact your healthcare team right away:

  • Cough
  • Fever
  • New Rash
  • Pink Eye

OR

If you been around someone with measles or someone who has ANY symptoms of measles

DO NOT COME TO THE CANCER CENTER.
