Impact of the pneumococcal conjugate vaccines on invasive pneumococcal disease in France, 2001-2012

Vaccination with PCV13 was rapidly followed by a decrease in the incidence of all-type IPD in children, in relation with a sharp decrease in the incidence of PCV13-Non PCV7-IPD. Moreover, all-type IPD decreased after PCV13 introduction in older non-vaccinated age-groups, with a shift in the distribution of serotypes. Considering the whole 2001-2012 period, the vaccination with PCV7 and PCV13 resulted in a decline in the incidence of IPD in children up to the age of 5 but not in older children and adults.
