Who is at highest risk for getting Pertussis?

Updated February 18, 2023

Young infants with developing immune systems, as well as older children, adolescents, and adults may be at risk for developing pertussis.  Studies have indicated that infants do not appear to receive substantial benefits from maternal antibodies, which may put them at a higher risk of developing pertussis.  For many individuals, the pertussis vaccine (DPT, DTaP, TDaP) does not give long lasting protection against the disease and some individuals will never develop temporary immunity despite receiving all recommended boosters.    ,   Over time, the temporary immunity individuals may acquire through vaccination wanes, which often results in outbreaks of B pertussis in fully vaccinated children, teenagers and adults. ,  ,  ,  

Other populations who may be at risk for developing pertussis include healthcare personnel or persons with weakened immune systems.
