“…This is in line with studies showing impaired humoral and cellular vaccination responses in patients under anti-CD20 treatment ( Moor et al, 2021 ; Pri-Paz Basson et al, 2022 ; Wu et al, 2022 ) and studies showing that glucocorticoids impair the immunogenicity of the COVID-19 vaccine ( Bugatti et al, 2021 ; Pri-Paz Basson et al, 2022 ). In contrast, in accordance with previous studies that found that the respective treatments do not significantly impair COVID-19 vaccination efficacy, we observed a decrease in CFRs for patients under anti-TNFα ( Dimopoulou et al, 2022 ; Pri-Paz Basson et al, 2022 ; Venerito et al, 2022 ), JAK inhibitor ( Winthrop et al, 2016 ; Mortezavi et al, 2021 ; Pri-Paz Basson et al, 2022 ), or thalidomide analog ( Jenner et al, 2021 ) treatment. For the thalidomide analogs group (median patient age 68 years, IQR 61–76 years) the evolution of the CFR over the course of the vaccination campaign is similar to what we observed for patients ≥65 years old in the general population (FAERS COVID-19 dataset, irrespective of treatment).…”
