Parents and family members are the primary source of pertussis transmission to vulnerable infants3

Talk to parents about the threat pertussis poses to their families, and how immunization with Tdap vaccine can help protect them

  • It is estimated that up to 3.3 million cases of pertussis occur each year in adults and adolescents in the United States2
  • Studies show that when the source can be identified, family members are the source of transmission in up to 83% of infant cases3
    • International multicenter study of 91 families3
      • Source cases were identified for 44 infants and described by relationship to the infant, age, and household status3
  • With a household attack rate reaching 90% to 100%, pertussis is highly contagious5,7

Cases of pertussis continue to be elevated.8 Yet, despite CDCb recommendations, only 8% of adults reported receiving Tdap vaccination from 2005 through 2010.23

  • Immunization with Tdap vaccine may help protect adults and adolescents against pertussis, and helps reduce the risk of transmission to vulnerable infants4
