Humoral immune response to SARS-CoV-2 vaccines in patients with autoimmune rheumatic diseases.

Background: Patients with autoimmune rheumatic diseases (ARD) are at increased risk of infection due to their impaired immune response, which also reduces vaccination efficacy. Although several studies have evaluated the serological response to SARS-CoV-2 mRNA-based vaccines in patients with ARD, limited information on immune responses to other vaccination platforms is available.

Aims: This observational prospective study aims to investigate the humoral immune response to different SARS-CoV-2 vaccines in patients with ARD.
