• Registration Number: NCT04086628
• Lead Sponsor: Central Hospital, Nancy, France

Brief Summary

The occurence of influenza can be a factor of imbalance of asthma. Asthma patients are recommended for annual influenza vaccination . However there is insufficient vaccination coverage of asthmatic patients despite this recommendation. The aim of this study is to evaluate the rate of influenza vaccination coverage of children with asthma aged from 6 month to 17 years of age followed in pediatric pneumology consultation at the university hospital of Nancy.

Detailed Description

Using a questionnaire, the investigator will estimate the percentage of the asthmatic patients vaccinated against influenza. He will then compare the 2 groups of vaccinated and unvaccinated patients : comparison of patients characteristics, comparison of asthma characteristics (severity, asthma control...). He will also analyze the causes of vaccination or non-vaccination.
