Clinical Trial Summary

The STOPCoV study is a decentralized study comparing COVID-19 vaccine specific antibody levels at 24 weeks after final vaccine dose. We plan to study the safety and immunogenicity of COVID-19 vaccine(s) in community dwelling persons 70 years and over relative to a younger group (aged 30 - 50 years).

Clinical Trial Description

This is a prospective observational study of a cohort of individuals aged 30-50 years and a cohort of individuals aged 70 years and over receiving the COVID-19 vaccine. Participants will complete a questionnaire to determine eligibility. Eligible participants will complete and sign an e-consent and then be provided with a participant ID, log in information and password to the database portal, and then be enrolled into the study. Participants will complete the study assessments (baseline questionnaire, post vaccine symptom e-diary monthly, check-in questionnaire and dried blood spot specimens) ;
