Measles causes ‘immune amnesia,’ leaving patients vulnerable to repeat infections
Two studies investigating the immune systems of unvaccinated children in the Netherlands demonstrated that measles virus can give patients “immune amnesia” — that is, it erases the immune system’s memory of past encounters with other pathogens, leaving them vulnerable to future infections.
