Table 3.

Age and Cycle Threshold Value by Vaccination Status

Variable Unvaccinated + Early Post-Vaccination Partially + Fully Vaccinated P Value
Age, mean (SD), years 36.8 (10.2) 42.3 (11.8) <.001
Cycle threshold value (n = 98), mean (SD) 22.9 (7.3) 27.9 (8.2) <.001

T tests comparing age and cycle threshold value by vaccination status. Early post-vaccination = positive severe acute respiratory syndrome coronavirus 2 nucleic acid amplification test  <14 days from vaccine dose 1, partially vaccinated = >14 days from vaccine dose 1 and <14 days from vaccine dose 2, fully vaccinated = >14 days from vaccine dose 2.

Abbreviation: SD, standard deviation.
