Sustained Humoral and Cell-Mediated Immunogenicity of COVID-19 Vaccines in Patients With Inflammatory Bowel Disease
The aim of this study is to determine the impact of systemic immunosuppression on sustained antibody COVID-19 concentrations in patients with IBD who received a COVID-19 vaccine.
A patient will be eligible for inclusion in this study if he or she meets all the following criteria:

Should be on stable doses defined as: Group A should have taken a dose of medication within the past week; Group B infliximab within the previous 8 weeks, golimumab within the previous 4 weeks, adalimumab within the previous 2 weeks, or certolizumab within the previous 4 weeks; Those on combination therapy in group B will have taken azathioprine or methotrexate within the past week. Group C ustekinumab at least within the previous 4 weeks. Those on combination therapy in group C will have taken azathioprine or methotrexate within the past week; Group D vedolizumab at least within the previous 4 weeks. Those on combination therapy in group D will have taken azathioprine or methotrexate within the past week
