Infection amnesia: Measles 'destroys immune system memory'
Getting measles is even more dangerous than doctors had realized, because it destroys immunity that the victim has acquired to other diseases, researchers said on Thursday.
Conclusions: The increased risk for nonspecific infectious disease hospitalizations supports the concept of immunologic amnesia after measles. Universal immunization against measles provides additional benefit beyond protection against measles itself.

Measles infection can greatly reduce acquired immune memory, according to a new study. Acquired immune memory is when a person's immune system attacks foreign invaders and can remember how to fight the dangerous antigens in the future. "Measles virus infects immune cells, particularly long-term immune memory cells, causing immune "'amnesia'" which can last for varying amounts of time," [...]
New research shows the virus can have devastating effects on the immune system that persist much longer than the illness itself.
The virus can cause 'immune amnesia' which shifts our defences back to a 'baby-like' state.
A measles infection can cripple a child's immunity against viruses and bacteria for the long-term, leaving them more vulnerable to future infections.
Not so long ago, coming down with measles was seen almost as a rite of passage. Before measles vaccination began in the U.S. in the early 1960s, millions of Americans, many of them children, contracted the virus each year—forcing them to weather a flu-like illness and telltale skin rash, but also bestowing lifelong immunity. As a result, some Americans still view measles as relatively harmless—which, in addition to a dangerous uprising of anti-vaccine sentiment, has led some parents to decline shots for their children, contributing to a resurgence of preventable illness in the U.S. and overseas. A pair of relat...
Study reveals how measles infection reduces protection against other diseases
Thakkar and McCarthy suggest that periodicity in measles incidence artifactually drives our estimates of a 2- to 3-year duration of measles "immune-amnesia." We show that periodicity has a negligible effect relative to the immunological signal we detect, and demonstrate that immune-amnesia is largely undetectable in small populations with large fluctuations in mortality of the type they use for illustration.
