Patients with inflammatory bowel disease (IBD) are recommended to receive vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), regardless of their immunosuppression status. Immunosuppressive medications represent a mainstay of therapy in moderate to severe IBD; however, their impact on the SARS-CoV-2 vaccine response remains unclear. Studies thus far have shown that patients with IBD on various therapies had detectable antibody responses after standard vaccinations.1-5 To date, one study has examined the kinetics of antibody response at 3 months after vaccination in patients with IBD, but data beyond this time point are not yet available.6 The aim of this study was to assess anti-spike antibody response 6 months after completion of standard SARS-CoV-2 vaccination in patients with IBD. Secondarily, we observed antibody kinetics over 6 months in a subset of patients post-vaccination.
