Pediatric Pertussis in Ambulatory Settings

Since 2002, Whooping cough surveillance in pediatric private practice has been set up in France. The results of the first years, 2002-2006, have confirmed the effectiveness of the Pertussis whole-cell (Pw) vaccine and in particular the duration of protection of 9/10 years. After evaluating cases in children vaccinated with Pw vaccines, the study aims today to analyze cases in children vaccinated with Pertussis acellular (Pa) vaccines used since 2002/2003 and to assess, on an outpatient basis, the impact of new vaccine recommendations in France (in 2013, introduction of a 2 + 1 schedule - 8 weeks, 4 months and a 11-month recall - and a 6-year recall, and in 2014, update in the recommendations of exams to be prescribed based on the child's age and vaccination status).
