Vaccines Save Lives

Measles was declared eliminated in the United States in 2000. Now it's back and on the rise, fueled by vaccine hesitancy and a lack of awareness of just how deadly it can be.  

UNICEF and partners are working tirelessly all over the world to save and protect children. 



Measles is highly contagious — more than Ebola, tuberculosis or influenza — and potentially deadly. But thanks to a highly effective vaccination program, measles was declared eliminated in the U.S. in 2000.

Unfortunately, that's not the end of the story.

As of March 28, 387 cases of measles have been reported this year in the U.S., according to the Centers for Disease Control and Prevention (CDC). In 2019, measles cases have been reported in 15 states: Arizona, California, Colorado, Connecticut, Georgia, Illinois, Kentucky, Michigan, Missouri, New Hampshire, New Jersey, New York, Oregon, Texas and Washington. 

Why is measles — a highly contagious, vaccine-preventable respiratory illness — on the rise in the U.S.? 

Public health experts blame complacency and the antivaxxer movement for this alarming increase. Most people who get measles are unvaccinated. Outbreaks in the U.S. typically start when travelers contract measles abroad and then bring it home. If they happen to live in a community of unvaccinated people, the disease spreads even more rapidly. According to the CDC, up to 90 percent of nonimmunized people who are exposed to the virus will become infected. 

The latest outbreaks have been fueled by the antivaccine movement and a lack of awareness about just how deadly measles can be

Parents who opt out of immunizing their children are putting their health — and possibly their lives — at risk. Before the measles vaccine became available in 1963, between 3 and 4 million people were infected with measles in the U.S. each year. An estimated 400 to 500 people died, 48,000 were hospitalized and 1,000 suffered encephalitis (swelling of the brain). 

Vaccines protect children from dangerous infectious diseases

Vaccines have an excellent safety record and most "vaccine scares" have proven to be false alarms. Immunization is one of the most cost-effective public health interventions to date, preventing an estimated 2 to 3 million deaths every year. 

"Almost all of these measles cases are preventable, and yet children are getting infected even in places where there is simply no excuse," said UNICEF Executive Director Henrietta Fore. "Measles may be the disease, but, all too often, the real infection is misinformation, mistrust and complacency. We must do more to accurately inform every parent, to help us safely vaccinate every child."

UNICEF is committed to vaccinating every child, everywhere. Please support UNICEF's immunization efforts. 




For more than 70 years, UNICEF has been putting children first, working to protect their rights and provide the assistance and services they need to survive and thrive. With a presence in 190 countries and territories, UNICEF has helped save more children's lives than any other humanitarian organization in the world.
