Take the Adolescent Immunization Quiz

Thanks to vaccines, most U.S. children are protected against serious diseases such as measles, mumps, diphtheria, polio, and chickenpox. But what happens to that protection in adolescence? A teen who missed a vaccination or booster as a child may need to be immunized. Sometimes a teen's living situation or medical condition makes it necessary to get a vaccination. Other vaccines lose their protective power over time, and teens and young adults need a booster to stay protected.
