ABSTRACT

We demonstrate low rates of breakthrough coronavirus disease 2019 (COVID-19) infection and mild course of illness following severe acute respiratory syndrome coronavirus 2 vaccination in a large cohort of inflammatory bowel disease patients. Residence in southern United States and lower median anti-receptor binding antibody level were associated with development of COVID-19.

ABSTRACT

INTRODUCTION: Although an additional coronavirus disease 2019 vaccine dose for immunocompromised persons has been recommended in some countries, further data to guide vaccination strategies for patients with inflammatory bowel disease (IBD) are urgently needed. We sought to identify factors affecting initial humoral immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines among patients with IBD. METHODS: In this prospective cohort of SARS-CoV-2 immunized patients with IBD, we evaluated associations between participant age, sex, vaccine type, medication use, and the presence of a detectable antireceptor binding domain antibody and quantitative antibody level. RESULTS: In total, 1,909 participants were included (1,123, 692, and 94 received BNT162b2, mRNA-1273, and Ad26.COV2.S, respectively) of whom 96% achieved a positive antibody response. On multivariable analysis, factors associated with lack of antibody response were older age (P = 0.043), BNT162b2 vs mRNA-1273 (odds ratio [OR] 2.1, 95% confidence interval [CI] 1.0-3.9), and combination therapy with anti-TNF and 6MP, azathioprine, or methotrexate (OR 4.2, 95% CI 2.4-7.3). The use of 5-aminosalicylate or sulfasalazine (OR 0.3, 95% CI 0.1-0.8) and ustekinumab (OR 0.2, 95% CI 0.05-0.8) was associated with decreased odds of lacking antibody response. DISCUSSION: Most patients with IBD mount an initial response to SARS-CoV-2 vaccination; however, older patients and those treated with anti-TNF and immunomodulator have blunted responses and may benefit the most from an additional vaccine dose. Patients treated with other classes of immunosuppressive medications have more robust initial immune responses to vaccination. These data should inform key decisions about patient selection for additional coronavirus disease 2019 vaccine doses in patients with IBD.

ABSTRACT

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 vaccination is recommended for all individuals with inflammatory bowel disease (IBD), including those on immunosuppressive therapies; however, little is known about vaccine safety and efficacy in these patients or the impact of vaccination on IBD disease course. METHODS: We evaluated coronavirus disease 2019 (COVID-19) vaccine-related adverse events (AEs) and the effect of vaccination on IBD disease course among participants in the PREVENT-COVID (Partnership to Report Effectiveness of Vaccination in populations Excluded from iNitial Trials of COVID) study, a prospective, observational cohort study. Localized and systemic reactions were assessed via questionnaire. Disease flare was defined by worsening IBD symptoms and change in IBD medications. Outcomes were stratified by vaccine type and IBD medication classes. RESULTS: A total of 3316 individuals with IBD received at least 1 COVID-19 vaccine. Injection site tenderness (68%) and fatigue (46% dose 1, 68% dose 2) were the most commonly reported localized and systemic AEs after vaccination. Severe localized and systemic vaccine-related AEs were rare. The mRNA-1273 vaccine was associated with significantly greater severe AEs at dose 2 (localized 4% vs 2%, systemic 15% vs 10%; P < .001 for both). Prior COVID-19 infection, female sex, and vaccine type were associated with severe systemic reactions to dose 1, while age <50 years, female sex, vaccine type, and antitumor necrosis factor and vedolizumab use were associated with severe systemic reactions to dose 2. Overall rates (2%) of IBD flare were low following vaccination. CONCLUSIONS: Our findings provide reassurance that the severe acute respiratory syndrome coronavirus 2 vaccine is safe and well tolerated among individuals with IBD, which may help to combat vaccine hesitancy and increase vaccine confidence.


The severe acute respiratory syndrome coronavirus 2 vaccine is safe and well tolerated among individuals with inflammatory bowel disease (IBD). Severe localized and systemic vaccine-related adverse events were rare, and rates of IBD flare were low (2%) following severe acute respiratory syndrome coronavirus 2 vaccination in a cohort of 3316 participants with IBD.
