New pneumococcal conjugate vaccines (PVCs) that have a wider coverage range and that will probably replace PCV7 in universal immunization programmes have been recently authorized. The social burden ascribable to pneumococcal disease in Italy is controversial and the utilization of PCV7 seems not to have contributed to its reduction as it was hoped; at the same time a displacement of the strains responsible for pneumococcal disease has been observed with a reduction in vaccine strains and an increase in non-vaccine strains that before were less frequent. At present there is the opportunity to assess the epidemiology of the pnemococcal disease and its variation after vaccination.
