CDC update on pertussis surveillance and Tdap vaccine recommendations.

Pertussis is the most poorly controlled bacterial vaccine-preventable disease. Since the early 1980s there has been an increase in reported cases of pertussis. Multiple factors have likely contributed to the increase, including waning immunity, increased recognition, and changes in diagnostic testing and reporting. Of the four combination vaccines used to prevent diphtheria, tetanus, and pertussis, one dose of Tdap should be used to vaccinate preteens as well as teens and adults who have not yet received this booster dose. It is the position of NASN that immunizations, including the Tdap vaccine, are key to primary prevention of diseasefrom infancy through adulthood. The school nurse is in a critical position to create awareness and influence action-related national and state recommendations for the Tdap vaccine.
