Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are children who have been diagnosed with invasive pneumococcal disease and have a confirmed isolate of Streptococcus pneumoniae.

Probably not a fit

Patients who do not have a confirmed pneumococcal infection or whose strains are not transmitted to the National Reference Center for Pneumococci may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to assess the effects of the 7 and 13 valent pneumococcal conjugate vaccines implemented in France on invasive pneumococcal disease (IPD) in children. It will involve the collection and analysis of clinical data related to IPD cases, including serotyping of the pneumococcus, underlying health conditions, and vaccination status of the affected individuals. The study will utilize isolates from various sterile body sites to understand the epidemiology of IPD post-vaccination.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness of pneumococcal vaccines in reducing severe infections in children.

How similar studies have gone: Other studies have shown success in evaluating the impact of pneumococcal vaccines on disease incidence, making this approach both relevant and supported by prior findings.
