Respiratory tract infections are among the leading causes of death worldwide and many of these infections are preventable through vaccination. One of the most important bacteria from an etiological and mortality point of view regarding respiratory and systemic infections is the gram-positive Streptococcus pneumoniae. Four types of vaccines are currently available for this pathogen: three pneumococcal conjugate vaccines (PCV13, PCV15, and PCV20) and one polysaccharide vaccine (PPSV23). In Italy, people over 65 years of age and people suffering from chronic pathologies with effects on the immune system would be advised to be vaccinated with the pneumococcal conjugate vaccine and with the polysaccharide vaccine as a second dose. However, there are no data available in Italy on vaccination coverage in these population categories and above all the vaccination rates in patients who have a history of an episode of invasive pneumococcal infection are not known. The aim of the study is to measure how many patients are vaccinated for S. pneumoniae after hospitalization for a systemic pneumococcal infection in order to understand patients' awareness of preventing this infection after receiving a first diagnosis.

Rate of antipneumococcal vaccination in hospitalized patients for invasive pneumococcal infection between 2015 and 2019.
Timeframe: The information regarding vaccination after the infectious episode will be assessed by consulting the SIAVR portal or the vaccination booklet in a period between at least one month from discharge and up to 06/30/2023.
