Clinical Trial Summary

To determine whether providing a recombinant booster COVID-19 vaccine improves sustained humoral and cell-mediated immunogenicity against SARS-CoV-2 in immunosuppressed patients with Inflammatory Bowel Disease (IBD) and/or solid organ transplant recipients. 120 participants will be enrolled and can expect to be on study for 6 months.


Clinical Trial Description

This will be a single-center, prospective, unblinded, non-randomized study of 120 immunosuppressed patients who are planning to receive a recombinant COVID-19 vaccine booster dose as standard of care and are willing to participate in the study. At least 35 patients will have inflammatory bowel disease and at least 35 patients will be a solid organ transplant recipient. After obtaining informed consent, individuals who meet the inclusion criteria and none of the exclusion criteria will be invited to participate in the study. Blood samples will be collected from each participant at the baseline visit (V1), at 1 month post-booster (V2 visit), and 6 months post-booster (V3). Aim 1: To determine whether providing a recombinant booster COVID-19 vaccine improves sustained humoral and cell-mediated immunogenicity against SARS-CoV-2 in immunosuppressed patients with IBD and/or solid organ transplant recipients. The investigators hypothesize that solid organ transplant recipients receiving a combination of immunosuppressive regimens will have lower antibody concentrations than patients with IBD because previous work has shown that patients with IBD have higher rates of seroconversion than solid organ transplant recipients. ;
