Chickenpox is very easy to catch.

If someone in your family gets chickenpox and you haven't had it, or been vaccinated against it, you have a 9 in 10 chance of getting it.¹

Almost everyone in the United States used to get chickenpox. But chickenpox has become much less common, because 4 out of 5 children now have the chickenpox vaccine (to learn more, see What treatments work for chickenpox?). The vaccine has been used in the Unites States for 10 years.

Before the vaccine was used:²

• About 4 million people got chickenpox each year
• About 4,000 to 9,000 people needed hospital treatment for chickenpox each year
• About 100 people died from chickenpox each year.
