Conditions

Outcome Measures

Primary Outcomes (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 Outcomes (2)

  • 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

  • To compare the off-kinetics of IgG positivity against SARS-CoV-2 by natural infection vs vaccination

    Up to 9 months

Study Arms (2)

Unvaccinated SARS-CoV-2 positive

Participants who have tested positive for SARS-CoV-2, both with and without symptoms, who have not been vaccinated

Other: SARS-CoV-2

Vaccinated

Participants who were vaccinated against SARS-CoV-2

Other: SARS-CoV-2
