This study is a clinical trial designed to assess the impact on influenza vaccination rates among people aged over 65 of a telephone text message recalling them to be vaccinated by their GP. Twenty-two GPs will be randomly selected in each arm (recall versus usual care, 1:1). Each GP will include a maximum of 210 patients by random selection from their patient list. A difference of 4 percentage points is expected between the two arms at the end vaccination campaign in the vaccination rate.
This is an open-label trial with 2 arms: an interventional or "recall" arm and a "usual care" or control arm. Cluster randomization at the physician level was chosen to avoid contamination within the same patients group. Physicians will be randomized at the start of the vaccination campaign in one of the two arms (1:1), and all patients eligible (with a maximum of 210 per doctor) to be vaccinated will be recalled or not, depending on their GPs arm.

At mid-campaign, GPs in the interventional arm will recall their patients to be vaccinated via the reminder module Eo software * This recall will be carried out as follows: patients whose medical records include a number likely to receive telephone text messages will be recalled by this means Two generic messages that doctors can choose will be proposed by the call-back module integrated into the Eo medical software * In addition, the recall module will offer to send a postal letter with the same content as the text message to patients who do not have a mobile phone number in the business software but do have a postal address * The recall module will also provide the doctor with a list of patients who have neither a mobile phone number or a postal address, so that he can recall them to be vaccinated orally by landline telephone or in consultation when they next visit. The type of recall and the date of it will be notified in the medical file of each patient.

RECRUITINGThe influenza vaccination rate will be calculated as the ratio between the number of patients vaccinated (those who will report having been vaccinated in the questionnaire send at the end of the campaign) and the number of patients aged 65 years and over
The influenza vaccination rate will be calculated as the ratio between the number of patients vaccinated (i.e., those who will report having been vaccinated during the vaccination campaign in the questionnaire send at the end of the campaign) and the number of patients aged 65 years and over.
Time frame: 12 months
1/ Social inequalities related to the intervention, based on individual and ecological indicators (social deprivation index for example) will be estimated via absolute indicators (SII: slope of the inequality index) and relative (RII: relative inequality
At the end of the vaccination campaign, the GPs will send patients a postal mail containing: an accompanying explanatory letter, the patient questionnaire, and a pre-addressed and prepaid envelope for the return of the completed questionnaire to their attending physician.
Time frame: 1 year
2/ Acceptability of reminders (in the intervention arm only) based on the description of the patients answers to the related question in the questionnaires. This outcome is assessed by questionnaire.

4/ Characteristics of participating GPs based on the description of the physicians answers to the related question in the questionnaires. These outcomes are assessed by the physician questionnaire.
At the beginning of the study, participating GPs will answer a short questionnaire about their main characteristics (Sex, Date of birth, Size of the patients list...).
