Why do We Care About Measles Infections?

• Recent measles outbreaks in the U.S. and Canada have raised concern and renewed awareness about the disease’s severity.
• Measles is more dangerous than many realize because it causes “immune amnesia,” erasing the body’s memory of previous immunity.
• After a measles infection, the immune system forgets how to fight off other routine illnesses.
• This immune suppression increases vulnerability to severe disease from common infections such as colds and ear infections.
• Preventing measles through vaccination is key to maintaining immune protection against many illnesses.
