Over a hundred million infants receive measles vaccines annually

Over 100 million infants are vaccinated against measles every year, which means more than 80% of one-year-olds are protected from this potentially life-threatening disease. This global effort has saved millions of lives.

That scale should be reassuring. Measles vaccines are safe and reduce the risk of infection by over 95%, making them one of our most powerful tools to prevent childhood deaths. Outbreaks have become increasingly rare in many countries, global infant mortality has fallen, and measles vaccination alone is estimated to have saved more than 94 million lives.

But that progress is under threat: vaccination rates have fallen in recent years, as the chart shows, and fewer children are getting the protection they need. When coverage slips, measles spreads rapidly; more children suffer and die from a disease we can easily prevent.
