About The Study: In this study of 57,460 pertussis (also known as whooping cough) cases in the United States, following maternal tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine introduction, a sustained decrease in pertussis incidence was observed among infants younger than 2 months, narrowing the incidence gap with infants ages 6 months to less than 12 months. These findings suggest that maternal Tdap vaccination is associated with a reduction in pertussis burden in the target age group (younger than 2 months) and that further increases in coverage may be associated with additional reductions in infant disease.
