About this study

Official title: Factors Influencing the COVID-19 Vaccine Immune Response (Reactogenicity and Immunogenicity) According to Age and Presence or Not of a Past History of COVID-19

Age is the main risk factor associated with the severity of COVID-19. From the beginning of the vaccination campaign, elderly subjects are part of the priority population. However, immunosenescence appears to play a role in the natural post-COVID-19 immunity of convalescent elderly subjects and also in the post-vaccination response. However, vaccination recommendations for both naïve (2 doses of vaccine) and convalescent subjects (1 dose of vaccine) do not differ according to age. To date, there is little data to suggest that the response to the vaccine in naïve or convalescent subjects may vary according to age in terms of qualitative and quantitative response and duration.

Read the detailed description

In addition, the reactogenicity following the vaccine, remains important with COVID-19 vaccines, whether using an Messenger RiboNucleic Acid (mRNA) technique or an adenovirus vector technique. A better understanding of the parameters of early inflammatory response explaining this reactogenicity would allow to optimize the formulation of future vaccines. There are still several unknowns concerning the post-vaccination immune response (immunogenicity and reactogenicity) in older subjects,depending on their history of COVID-19 and the type of vaccine administered. A better understanding of this immune response is necessary in order to propose the best vaccine strategies and regimens in this high-risk COVID-19 population.

Thus, in partnership with Sanofi Pasteur and Bioaster, the Group On Mucosal Immunity And Pathogens (GIMAP) and Circulating Immune Complexes (CIC) vaccinology team proposes to conduct a study comparing the humoral, cellular, mucosal and reactogenic post-vaccination immune response in subjects with a history of COVID-19 >3 months ago (convalescent, 1 dose of vaccine) versus subjects with no history of COVID-19 (naive, 1 or 2 doses of vaccine depending on the type of vaccine used) according to age.

What is being measured

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

  1. Anti-S neutralizing antibody titer

    The neutralizing antibody titer against protein S from the majority variants at the time of sampling and vaccine S will be evaluated in viral neutralization and pseudoneutralization

    Measured: Days : 15, 90, 180 after each dose of vaccine

Secondary outcomes (9)
  1. Kinetic of Anti-S antibody titer

    The antibody titer against protein S will be evaluated by ELISA

    Measured: Days : 15, 90, 180 after each dose of vaccine

  2. Kinetic of Anti-N antibody titer

    The antibody titer against protein N will be evaluated by ELISA

    Measured: Days : 15, 90, 180 after each dose of vaccine

  3. Kinetic of Anti-SARS-CoV-2 immunoglobulin A (IgA) titers in saliva

    Measured: Days : 15, 90, 180 after each dose of vaccine

  4. Kinetic of SARS-CoV-2 quantiferon value

    Measured: Days : 15, 90, 180 after each dose of vaccine

  5. CD4 and CD8 lymphocyte polarization specific to the vaccine S protein

    Evaluate by TruCulture (Myriad) methode

    Measured: Days : 15 (group Naive and convalescent), 180 (group Boost only) after last dose of vaccine

  6. Anti-S neutralizing antibody titer

    The neutralizing antibody titer against protein S from the majority variants at the time of sampling and vaccine S will be evaluated in viral neutralization and pseudoneutralization

    Measured: Days : 15, 90, 180 after each dose of vaccine

  7. Kinetic of serum cytokine levels

    Measured: At 24 and 72 hours after each dose of vaccine

  8. Kinetic of C-reactive protein

    Measured: At 24 and 72 hours after each dose of vaccine

  9. Kinetic of vaccine-induced genes signatures

    Expression kinetics in foldchange (transcriptomics) of vaccine-induced gene signatures in peripheral blood mononuclear cells

    Measured: At 24 and 72 hours after each dose of vaccine

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing COVID-19 vaccine Pfizer (3 doses), COVID-19 vaccine Pfizer (2 doses) and COVID-19 mRNA Vaccine Moderna (3 doses) in people with Covid19, run by Centre Hospitalier Universitaire de Saint Etienne at 2 sites 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 4 inclusion and 8 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 11 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Anti-S neutralizing antibody titer (time frame: Days : 15, 90, 180 after each dose of vaccine). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 Dec 2024.
