Assessing immune responses to COVID-19 vaccines through remote participation

Longitudinal Assessment of Potential Immunologic Correlates of Risk and Protection Following COVID-19 Vaccination Comparing Remote and Site-based Specimen Collection (feasibility, Validity, and Proof of Concept)

Observational Biomedical Advanced Research and Development Authority · NCT06776367

This study is testing how well COVID-19 vaccines work by collecting blood and saliva samples from vaccinated people at home over a year to see if they can predict who might get sick.

What this trial studies

This observational study aims to evaluate immunological biomarkers from blood samples to predict the effectiveness of COVID-19 vaccines against symptomatic cases. Participants will be enrolled after receiving a COVID-19 vaccine and will provide saliva and blood samples remotely over a 12-month period. The study will assess the feasibility of self-collected specimens and virtual consultations, allowing participants to engage without frequent in-person visits. Weekly symptom reporting and nasal swab testing will also be conducted to monitor COVID-19 symptoms.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have completed an FDA-approved COVID-19 vaccination series.

Not a fit: Patients who have not received a COVID-19 vaccine or are unable to comply with remote participation requirements may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of vaccine efficacy and improve pandemic preparedness.

How similar studies have performed: Other studies have successfully utilized remote participation and self-collection methods, indicating potential for this approach.
