Since the beginning of 2020, a major pandemic due to the new emerging coronavirus (SARS-CoV-2) has been spreading around the world. Today, the hope to contain this pandemic lies in the development and use of vaccines directed against this virus. Different strategies aim to maximize the early impact of vaccination in a context where few doses are available.
In early January 2021, large-scale vaccination began in France, first for populations at risk of severe COVID-19, but also for healthcare workers over 50 years of age or with an underlying pathology, and then for all voluntary healthcare workers.
The question of vaccination of patients with a history of recent or late SARS-CoV-2 infection has rapidly become a major issue. Currently, French recommendations call for a single dose in the cohort that has been cured of COVID-19 for six months. In addition, the use of anti-SARS-Cov2 serology may be of interest because the presence of antibodies indicates recent or past contact with SARS-CoV-2. However, serological testing is not included in the vaccination decision strategy.
The goal of the investigators is to provide data on the immune response induced by SARS-CoV-2 vaccines in a real-world setting to support this choice. Given the absence of recommendations concerning the realization of the anti-SARS-CoV-2 serology, it will be proposed to all the nursing staff of the Groupe Hospitalier Paris Saint Joseph at the time of their vaccination, a serological screening.
The investigators will evaluate the dynamics of antibody production against the SARS-CoV-2 Spike protein after the first and second dose of vaccine (conventional prime-boost strategy recommended) in healthcare workers with or without a history of COVID-19.
7,640 studies on the registry are indexed under COVID-19; 488 are open to participants now.
This study's enrollment of 73 is below the median of 261 across 3,136 observational studies indexed under COVID-19.

This study will be carried out on the data of health care workers referred for vaccination to the Occupational Medicine Department and having received anti-SARS-CoV-2 serology at Day 21 post injection between 01/01/2021 and 31/03/2021, i.e. approximately 100 patients in total
Exclusion Criteria:
To evaluate the level of serological response after the first and second vaccine doses in health care workers with and without a history of COVID-19.
Evolution of of anti-SARS-CoV-2 antibody level at D21-28 post-first dose and at D21-28 post-second dose in healthcare workers with and without a history of COVID-19.
Time frame: Day 28
