Epidémiologie récente de la coqueluche: Implications pour la vaccination

The development of acellular pertussis vaccines allowed since more than a decade to continue beyond the 2 first years of life the immunization against this illness. This technological progress should have led to an improvement in the control of the disease. However, despite high immunisation rates in infancy, Bordetella pertussis is still circulating in the population. Since 2010 a marked increase in the number of cases of whooping cough in infants too young to be vaccinated, as well as in older children and in teenagers, has been reported in a number of north-American states and in the United-Kingdom. A similar observation has been made in Belgium in 2012 and 2013. The limited duration of the protection resulting from vaccination is probably responsible for the insufficient control of the disease. The new approaches for the use of these vaccines that are proposed to protect the most vulnerable young infants will be discussed.SCOPUS: ar.j
