Fondation Merieux webcast 2015. Pertussis modeling: contributions of natural and vaccines immunity on the epidemiology. http://www.fondation-merieux.org/pertussis-biology-epidemiology-and-prevention-2015-webcasts
Pertussis, commonly called whooping cough, is a highly infectious disease that was previously a universal rite of passage for older infants and young children. The discovery in 1906 of its causative organism, Bordetella pertussis, led to the development of whole-cell pertussis (wP) vaccines, which by the 1930s were combined with diphtheria (D) and tetanus (T) toxoids. Countries that instituted broad DTwP vaccination programs beginning in the mid-20th century saw pertussis dramatically decrease over subsequent decades. However, concerns over reactogenicity prompted some parents to refuse wP-containing vaccines for their children and some countries to cancel their programs altogether. Less reactogenic acellular pertussis (aP) vaccines were developed to address these concerns. They were deployed in Japan nearly 35 years ago, North America and much of Europe about 15 to 20 years ago, and more recently in some other middle- and high-income countries.
During the last 5 years, multiple countries (eg, Australia, UK, US) have experienced substantial increases in reported cases of pertussis. Cases among very young infants who are at greatest risk of pertussisrelated hospitalizations and mortality were most alarming. Multiple hypotheses have been posited for the current challenges with pertussis, including:
