Measles has a stealth side effect: New research shows it erases much of the immune system’s memory of how to fight other germs, so children recover only to be left more vulnerable to bugs like flu or strep. Scientists dubbed the startling findings “immune amnesia.” The body can rebuild those defenses — but it could take years. And with measles...
