We describe a 5-year-old, fully immunized boy with PCR proven consecutive B. pertussis and B. parapertussis infections causing typical whooping cough at the age of 2 and 5 years, respectively. Neither pertussis immunization nor disease provides reliable immunity against further episodes of whooping cough.
