Abstract
Objective
The impact of medications on COVID-19 vaccine efficacy in IBD patients is unknown, as patients with immunosuppressed states and/or treated with immunosuppressants were excluded from vaccine trials. To address this, we evaluated serological responses to COVID-19 vaccination with the SARS-CoV-2 spike (S) mRNA BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (NIH-Moderna) vaccines in IBD patients enrolled in an ongoing SARS-CoV-2 sero-survey at the Icahn School of Medicine at Mount Sinai in New York City.
Design
We obtained sera from 48 patients who had undergone vaccination with one or two vaccine doses. Sera were tested for SARS-CoV-2 anti-RBD total immunoglobulins and IgG (Siemens COV2T and sCOVG assays), anti-Spike IgG (in-house ELISA), and anti-nucleocapsid antibodies (Roche).
Results
All IBD patients (15/15) who completed two-dose vaccine schedules achieved seroconversion to high levels. Two IBD patients with history of COVID-19 infections and who were seropositive at baseline seroconverted to high levels after the first dose. Concurrent biologic use was 85% (41/48), including 33% of patients (16) on TNF antagonist monotherapy, 42% (17) on vedolizumab monotherapy, 6% (3) on vedolizumab combination therapy with thiopurine, and 8% (4) ustekinumab; 1 patient was receiving guselkumab for psoriasis. Three patients (6%) were on oral steroids at the time of vaccination.
Conclusion
IBD patients receiving biologics can seroconvert with robust serological responses after complete Pfizer-BioNTech and NIH-Moderna COVID-19 vaccination. In IBD-patients with previous SARS-CoV-2 seroconversion, a single dose of either vaccine can induce high index values, mirroring findings from the general population.

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Despite these limitations, our results support the consensus recommendation for IBD patients to receive COVID-19 vaccines when available5. Our study also highlights the need for future studies to assess earlier time points and longitudinal studies to assess full immune responses, including cell-mediated responses, effects of other medications, and clinical efficacy of different vaccine types to guide optimal dosing regimens and/or vaccine choice in IBD patients.
