Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is to describe the humoral and cellular response to BNT162b2 vaccination in people over age 75 institutionalized in the long-term care units of the Paris Public Hospitals (APHP)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an interventional study with minimal risk and constraints, multicenter with biological collection. Two populations are studied: patients and members of care staff.

The following data will be collected:

* For patients and staff: age, gender, existence of Coronavirus Disease 2019 (COVID-19) infection and whether or not it is symptomatic and date of first positive RT-PCR test, medical history
* For patients: nutritional status (loss of appetite, weight loss, body mass index, albuminemia)

Vaccination antibodies are measured using 3 blood sample:

The first carried out before the anti-Coronavirus Disease 2019 (COVID-19) vaccination; the second on D21 (shortly before the vaccination booster injection) and the third on D50-54.

In addition, during the first sample, assays will be carried out informing us of your nutritional and inflammatory status.
