Abstract

Objectives To test whether patients with immune-mediated inflammatory disease (IMIDs), who did not respond to two doses of the SARS-CoV-2 vaccine, develop protective immunity, if a third vaccine dose is administered. Methods Patients with IMID who failed to seroconvert after two doses of SARS-CoV-2 vaccine were subjected to a third vaccination with either mRNA or vector-based vaccines. Anti-SARS-CoV-2 IgG, neutralising activity and T cell responses were assessed at baseline and 3 weeks after revaccination and also evaluated seprarately in rituximab (RTX) and non-RTX exposed patients. Results 66 non-responders were recruited, 33 treated with RTX, and 33 non-exposed to RTX. Overall, 49.2% patients seroconverted and 50.0% developed neutralising antibody activity. Seroconversion (78.8% vs 18.2%) and neutralising activity (80.0% vs 21.9%) was higher in non-RTX than RTX-treated patients with IMID, respectively. Humoral vaccination responses were not different among patients showing positive (59.3%) or negative (49.7%) T cell responses at baseline. Patients remaining on mRNA-based vaccines showed similar vaccination responses compared with those switching to vector-based vaccines. Conclusions Overall, these data strongly argue in favor of a third vaccination in patients with IMID lacking response to standard vaccination irrespective of their B cell status.
