Role of booster with BNT162b2 mRNA in SARS-CoV-2 vaccination in patients with rheumatoid arthritis.

ABSTRACT: Only case reports and small clinical series report the effects of booster vaccination with BNT162b2 in patients with rheumatoid arthritis (RA). We studied 200 patients with RA in clinical remission evaluated with the DAS28. All patients were vaccinated for SARS CoV-2 with the BNT162b2 mRNA vaccine. The value of anti-SARS-CoV 2 Spike RBD IgG antibodies was determined at T1 (3 weeks after first vaccination) and T2 (3 weeks after booster). In addition, patients underwent assessment of lymphocyte subpopulations by flow cytometry analysis before starting the vaccination cycle (T0). Furthermore, the serum antibody levels of 96 health care workers (HCWs) were analyzed for comparison. DAS28 values at T0, T1, and T2 indicated remission or low disease activity in all patients. Levels of anti-SARS Co
