Trial summary

Few trials have reported the safety and efficacy of the COVID-19 vaccines. However, these trials were mostly focused on post-vaccination adverse events and short-term antibody detection with none monitoring the presence of immunoglobulin G (IgG) in blood at long-term follow-up after the vaccination.

About this study

Official title: Immune Response Following COVID-19 Vaccination (IFVAC)

Few trials have reported the safety and efficacy of the COVID-19 vaccines. However, these trials were mostly focused on post-vaccination adverse events and short-term antibody detection with none monitoring the presence of immunoglobulin G (IgG) in blood at long-term follow-up after the vaccination. This study aims to evaluate the immune response in post-vaccinated individuals across a follow-up period of one year.

Read the detailed description

The COVID-19 pandemic started in December 2019 and since then has spread globally claiming over 550, 000 deaths, >12 million infections and an economic toll in the trillions of dollars to date. The urgent need for a global vaccination program to control this pandemic has prompted the development of several vaccines.

Preliminary reports from few trials evaluating the safety and efficacy of the vaccines have been published (2-4).

However, no trials have yet reported the long-term post-vaccination immune response that would potentially determine the necessity and timing for booster doses of the vaccine.

Therefore, this study is designed to assess the presence of immunoglobulin (Ig) M and G at several time points after the first and the second dose of the vaccine.

Being tested
Rapid antibody test
Medical subject headings
Hyper-IgM Immunodeficiency Syndrome, Type 1

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Rapid antibody testOther

    Serial serology tests on day 21, 90, 180 and 365 following the first dose of the COVID-19 vaccine to detect the temporal trend of the IgM and IgG production in response to the vaccination.

What is being measured

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

  1. Post-vaccination immune response

    To assess the time for appearance and persistence of IgM and IgG after COVID-19 vaccination.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of IgM and IgG in Blood, run by Texas Cardiac Arrhythmia Research Foundation at 1 site in United States.

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 1 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 3 Feb 2021. 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 United States. 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?

Results are not available in the source record.

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

Contact Angel Mayedo (5125447254, angel.mayedo@stdavids.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Post-vaccination immune response (time frame: 1 year). 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 3 Feb 2021.
