Kids infected with measles face long-term health consequences. Vaccines can prevent all of them.

Measles kills between 1 and 3 out of every 1,000 children infected with the viral disease. But even for those who survive the illness, the long-term consequences of measles can be serious. Long after a person recovers from their acute infection, their immune system is compromised — and in rare cases, the measles virus can hide out in the nervous system, roaring back to cause a fatal disease years later.
