Health Key

Cases of pertussis, a contagious disease that can be deadly for babies, is on the rise across all age groups in the United States because many adolescents and adults don’t realize they need a booster vaccine to stay immunized.

“I think the problem is that for such a long time, people have believed if you were vaccinated as a child or if you had had pertussis, you were protected,” said Dr. Tina Tan, professor of pediatrics at Northwestern University’s Feinberg School of Medicine and an infectious disease physician at Children’s Memorial Hospital.
