Yes. Adults who have a history of pertussis disease generally should receive Tdap according to the routine recommendation. This practice is recommended because the duration of protection induced by pertussis is unknown (waning might begin as early as 7 years after infection) and because diagnosis of pertussis can be difficult to confirm, particularly with tests other than culture for B. pertussis. Administering pertussis vaccine to persons with a history of pertussis presents no theoretical risk. http://www.cdc.gov/mmwr/PDF/rr/rr5517.pdf [419KB – 44 pages] (pages 24-25).
