Strong IgG antibody decline for medical personnel (n = 125).
| Risk factor | Estimate | 95% CI | p-value | OR, 95%CI (MICE) |
|---|---|---|---|---|
| Age | 1·037 | [0·993,1·082] | 0·101 | 1.028[1.021,1.034] |
| Sex (Ref. = female) | 1·611 | [0·515,5·042] | 0·413 | 1.930[1.710,2.180] |
| Vaccine type (Ref. = mRNA-1273) | 4·567 | [1·638,12·735] | 0·004 | 5.213[4.636,5.863] |
| BMI | 0·929 | [0·819,1·052] | 0·245 | 0.925[0.911,0.939] |
Ref. = reference category; a “strong IgG antibody declinestrong fading response” between T2 (two months after first vaccination) and T3 (six months) was defined as described in Results and in more detail in Supplementary material. BMI means body mass index. MICE means multiple imputation with chained equations.
Model fit: AIC = 107.44; BIC = 121.42.
