Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Nasopharyngeal sample

Arm Description

one will be taken nasopharyngeal all patients hospitalized for 24 hours with ILI in the last seven days.

Outcomes

Primary Outcome Measures

Measure of vaccine efficacy in population by comparing the number of influenza cases virologically documented in hospitalized patients vaccinated and unvaccinated.
The effectiveness of the vaccine in population will be calculated according to the formula VE = 1 - OR. an interval exact confidence of 95% will be calculated on the point estimate.

Secondary Outcome Measures

Measure of vaccine efficacy in population by comparing the number of influenza cases virologically documented in hospitalized patients vaccinated and unvaccinated according to age groups
Measure of vaccine efficacy in population by comparing the number of influenza cases virologically documented in hospitalized patients vaccinated and unvaccinated depending on the subtypes.
Description of the population hospitalized for ILI (socio-demographic characteristics, risk factors, pattern and duration of hospitalization...)

5. Study Description

Brief Summary
This study assesses the seasonal of influenza vaccine effectiveness in adults hospitalised with laboratory-confirmed influenza through a network of hospitals in France
Detailed Description
Influenza vaccination strategies aim at protecting high-risk population from severe outcomes. Estimating the effectiveness of seasonal vaccines against influenza related hospitalisation is important to guide these strategies. The objective is to measure the population effectiveness of influenza vaccine in patients hospitalized with virologically confirmed influenza laboratory during the influenza season 2012/2013 in a French hospitals network. This is a study "case-control" involving a nasopharyngeal sample for all hospitalised patients presenting an influenza-like illness within seven days. Cases will be patients RT-PCR positive for influenza. Controls will be patients negative for any influenza virus.
