NCT04664556

Brief Summary

After 7 then 13 valent pneumococcal conjugate vaccine (PCV) implementation in France in children, we will evaluate the impact of this vaccination on invasive pneumococcal disease (IPD). We will describe the clinical characteristics of IPD, pneumococcus serotyping, underlying conditions and vaccination status.
