Influenza Vaccine in Children With Asthma

Study Overview
=================
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.

| Percentage of asthmatic patients vaccinated against influenza | Percentage of patients vaccinated against influenza will be evaluate among children with asthma followed in pediatric pneumology consultation. | through study completion, an average of 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Socio-demographic characteristics of patients | Socio-demographic characteristics will be recorded from the questionnaire and compare between the 2 groups : vaccinated and unvaccinated patients. | through study completion, an average of 6 months | 
| Age of patients (years) | Age of patients will be recorded from the questionnaire and compared between the 2 groups : vaccinated and unvaccinated patients. | through study completion, an average of 6 months | 
| Asthma severity (mild, moderate, severe asthma) | Asthma severity (mild, moderate, severe asthma) is assessed from the level of treatment required to control symptoms according to Global Initiative for Asthma (GINA) 2018 recommendations. The investigator will compare asthma severity between the 2 groups : vaccinated and unvaccinated patients. | through study completion, an average of 6 months | 
| Asthma symptom control (well controled, partly controlled, uncontrolled) | Level of asthma symptoms control (well controled, partly controlled, uncontrolled) is assessed from symptoms control tool, according to GINA 2018 recommendations. The investigator will compare asthma symptom control between the 2 groups : vaccinated and unvaccinated patients. | through study completion, an average of 6 months |
