Primary endpoints
- Incidence of symptomatic and asymptomatic infection with SARS-CoV-2 and other respiratory viruses as determined by molecular (e.g. PCR) and serological testing
- Associations between the magnitude and quality of mucosal and serum antibody responses to SARSCoV- 2 and protection from infection with SARS-CoV-2
- Associations between the magnitude and quality of T cell responses to SARS-CoV-2 and protection from infection with SARS-CoV-2 Secondary endpoints
- Secondary attack rate and household cumulative infection rate with SARS-CoV-2, influenza, RSV, and other respiratory viruses
- Seroincidence and seroprevalence of SARS-CoV-2 a determined by binding antibodies to SARS-CoV-2 spike and nucleocapsid
- Presence of risk factors for symptomatic and asymptomatic infection with respiratory viruses
- Antibody and T cell kinetics of SARS-CoV-2 following infection
- Associations between the magnitude and quality of antibody and T cell responses to seasonal coronaviruses and protection from infection with SARS-CoV-2
- Associations between infection with non-SARS-CoV-2 respiratory viruses and protection from infection with SARS-CoV-2
- Associations between upregulation of gene expression in the mucosa, including interferon stimulated genes (ISGs), and protection from infection with SARS-CoV-2
