  1. aFully vaccinated was defined as completion of primary vaccination series greater than 2 weeks before enrollment.
  2. bVariant status was defined by viral sequencing results for 70 (67%) participants and by calendar time for the remaining 34 (33%) participants.
  3. cAny comorbidity was defined from the following list: history of autoimmune disease, cancer in the past 2 years, diabetes, HIV/AIDS, heart disease, hypertension, lung disease, or kidney disease.
  4. dRNA viral load measurements reported as log-transformed copies/mL.
  5. eAmong participants with a viral measurement, there were 52 (50%) who had maximum infectious viral load assessed, measured in plaque forming units.
  6. BMI body mass index, HS high school.
