Measles isn’t just a rash. For people with certain cancers or weakened immune systems from cancer treatment, measles can be especially dangerous. The CDC says people with compromised immune systems are at high risk for severe complications. Those complications can include pneumonia and encephalitis. There’s another concern for cancer patients: people with severely weakened immune systems may not be able to receive the live MMR vaccine. Exposure to measles can also disrupt cancer care and delay treatment. Vaccination doesn’t protect only you. It helps protect people who may not be able to protect themselves.
Talk to your physician. Get the facts. Get vaccinated.
