Investigating genetic factors related to COVID-19 vaccine adverse events

Official title: Genomics of COVID-19 Vaccine-induced Adverse Events (Guillain-Barré Syndrome [GBS], Vaccine-induced Immune Thrombotic Thrombocytopenia [VITT]/Thrombosis With Thrombocytopenia Syndrome [TTS], and Myocarditis/Pericarditis)

Run by University of British Columbia · NCT05212792 · Data updated 2026-11-12

This study is trying to find out if certain genes make some people more likely to have serious side effects from COVID-19 vaccines, like Guillain-Barré syndrome or myocarditis.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals who have received COVID-19 vaccines and developed GBS, VITT/TTS, or myocarditis/pericarditis.

Probably not a fit

Patients who have not received a COVID-19 vaccine or those unable to provide informed consent will not benefit from this study.

What this trial studies

This observational study aims to identify genetic factors that may increase the risk of severe adverse events following COVID-19 vaccination, specifically focusing on conditions such as Guillain-Barré syndrome (GBS), vaccine-induced immune thrombotic thrombocytopenia (VITT), and myocarditis/pericarditis. The research will involve a prospective case-control design, comparing individuals who experienced these adverse events with vaccinated controls who did not. Saliva DNA samples will be collected for genomic analysis, including candidate gene studies and genome-wide association studies (GWAS), to uncover potential genetic associations. The study seeks to enhance understanding of the biological mechanisms behind these adverse events to ultimately reduce their occurrence.

Why it matters

Potential benefit: If successful, this study could lead to improved safety measures and personalized approaches to COVID-19 vaccination, minimizing the risk of severe adverse events.

How similar studies have gone: While studies on vaccine adverse events exist, this specific investigation into genetic factors related to COVID-19 vaccine adverse events is relatively novel.
