- Cohort A - Incidence of treatment emergent adverse events [ Time Frame: Through Month 12 ]
- Cohort A - Ratio of SARS-CoV-2 sVNA titer against a relevant variant following VYD222 administration at Day 28 compared to a prespecified SARS-CoV-2 sVNA titer threshold. [ Time Frame: Day 28 ]
- Cohort B - Incidence of treatment emergent adverse events [ Time Frame: Through Month 12 ]
- Cohort A - Proportion of participants with sVNA titer against a relevant variant following VYD222 administration at Day 28 above a prespecified SARS-CoV-2 sVNA titer threshold. [ Time Frame: Day 28 ]
- Cohort A - sVNA titer by timepoint following VYD222 administration [ Time Frame: Through Month 12 ]
- Cohort A - Proportion of participants with sVNA titer against a relevant variant following VYD222 administration above a minimum SARS-CoV-2 sVNA threshold by timepoint [ Time Frame: Through Month 12 ]The minimum SARS-CoV-2 sVNA titer threshold will be prespecified prior to analysis.
- Cohort A - ADAs against VYD222 [ Time Frame: Through Month 12 ]
- Cohort A - Serum concentrations (PK) of VYD222 [ Time Frame: Through Month 12 ]
- Cohort A - Proportion of participants with RT-PCR-confirmed symptomatic COVID-19 [ Time Frame: Through Month 12 ]RT-PCR-confirmed symptomatic COVID-19 is defined as RT-PCR-confirmed SARS-CoV-2 with an onset of symptoms occurring no more than 14 days from the date of the positive RT-PCR test sample collection, COVID-19-related hospitalization, or all-cause death.
- Cohort B - Ratio of SARS-CoV-2 sVNA titer against a relevant variant following VYD222 administration at Day 28 compared to a prespecified SARS-CoV-2 sVNA titer threshold. [ Time Frame: Day 28 ]
- Cohort B - Proportion of participants with sVNA titer against a relevant variant following VYD222 administration at Day 28 above a prespecified SARS-CoV-2 sVNA titer threshold. [ Time Frame: Day 28 ]
- Cohort B - sVNA titer by timepoint following VYD222 administration [ Time Frame: Through Month 12 ]
- Cohort B - Proportion of participants with sVNA titer against a relevant variant following VYD222 administration above a minimum SARS-CoV-2 sVNA threshold by timepoint [ Time Frame: Through Month 12 ]The minimum SARS-CoV-2 sVNA titer threshold will be prespecified prior to analysis.
- Cohort B - Proportion of participants with RT-PCR-confirmed symptomatic COVID-19 [ Time Frame: Through Month 12 ]RT-PCR-confirmed symptomatic COVID-19 is defined as RT-PCR-confirmed SARS-CoV-2 with an onset of symptoms occurring no more than 14 days from the date of the positive RT-PCR test sample collection, COVID-19-related hospitalization, or all-cause death.
- Cohort B - COVID-19-related hospitalization or COVID-19-related death within 28 days of symptom onset [ Time Frame: Through Month 12 ]
- Cohort B - COVID-19-related death [ Time Frame: Through Month 12 ]
