Abstract

BACKGROUND AIM: Patients with inflammatory bowel diseases (IBD), specifically those treated with anti-tumor necrosis factor (TNF)alpha biologics, are at high risk for vaccine-preventable infections. Their ability to mount adequate vaccine responses is unclear. The aim of the study was to assess serologic responses to messenger RNA-Coronavirus Disease 2019 vaccine, and safety profile, in patients with IBD stratified according to therapy, compared with healthy controls (HCs). METHODS: Prospective, controlled, multicenter Israeli study. Subjects enrolled received 2 BNT162b2 (Pfizer/BioNTech) doses. Anti-spike antibody levels and functional activity, anti-TNF alpha levels and adverse events (AEs) were detected longitudinally. RESULTS: Overall, 258 subjects: 185 IBD (67 treated with antiTNF alpha, 118 non-anti-TNF alpha), and 73 HCs. After the first vaccine dose, all HCs were seropositive, whereas similar to 7 regardless of treatment, remained seronegative. After the second dose, all subjects were seropositive, however anti-spike levels were significantly lower in anti-TNF alpha treated compared with non-anti-TNF alpha treated patients, and HCs (both P < .001). Neutralizing and inhibitory functions were both lower in anti-TNF alpha treated compared with non-anti-TNF alpha treated patients, and HCs (P < .03; P < .0001, respectively). Anti-TNF alpha drug levels and vaccine responses did not affect anti-spike levels. Infection rate (similar to 2 and AEs were comparable in all groups. IBD activity was unaffected by BNT162b2. CONCLUSIONS: In this prospective study in patients with IBD stratified according to treatment, all patients mounted serologic response to 2 doses of BNT162b2; however, its magnitude was significantly lower in patients treated with anti-TNF alpha, regardless of administration timing and drug levels. Vaccine was safe. As vaccine serologic response longevity in this group may be limited, vaccine booster dose should be considered.
