About this study

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.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Day 28

Questions about this trial

What is this clinical trial studying?

An observational study of SARS CoV 2 Infection and Vaccination Reaction, run by Fondation Hôpital Saint-Joseph at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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. (time frame: Day 28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04934215, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jan 2022.
