Study Details

Study Description

Brief Summary

The primary objective of this study is to describe the longevity of IgG against SARS-CoV-2 infection or vaccination.

Condition or Disease Intervention/Treatment Phase
  • Other: SARS-CoV-2

Detailed Description

This virtual clinical study will use a prospective design, to evaluate longevity and seroprevalence of IgG against SARS-CoV-2 in approximately 800 patients as measured by Dried Blood Spots via fingerstick using the Everlywell COVID-19 Antibody Test Home Collection Kit. Participants will be followed up to 9 months at 1, 3, 6 and 9 months after enrollment.

Outcome Measures

Primary Outcome Measures

  1. To describe the longevity and seroprevalence of IgG against SARS-CoV-2 in a cohort of individuals exposed to SARS-CoV-2 [Up to 9 months]

Secondary Outcome Measures

  1. To compare the off-kinetics of IgG positivity against SARS-CoV-2, stratified by age, sex, race, ethnicity, infection symptomaticity, initial viral load [Up to 9 months]

  2. To compare the off-kinetics of IgG positivity against SARS-CoV-2 by natural infection vs vaccination [Up to 9 months]
