We can also learn more about which groups of people might not produce as many antibodies or maintain them as long as othersfor example, immunocompromised people compared with people who have healthy immune systems. In multivariable models, a positive antigen test result was more likely after 5 days than after 9 days (aOR=6.39; 95% CI = 3.3912.03), symptomatic infection (aOR=9.63; 95% CI = 6.0315.37), and less likely after previous infection (aOR=0.30; 95% CI = 0.190.46), receipt of a primary COVID-19 vaccination series (aOR=0.60; 95% CI = 0.390.93) or after both previous infection and receipt of a primary COVID-19 vaccination series (aOR=0.17; 95% CI = 0.090.33) (Table 2).
