RA patients treated with JAK inhibitors may need additional BNT162b2 COVID-19 vaccine boosts

Key clinical point: Patients with rheumatoid arthritis (RA) who were treated with Janus kinase (JAK) inhibitor showed reduced humoral response following 2 doses of BNT162b2 COVID-19 vaccine compared with healthy individuals.

Major finding: Patients with RA treated with JAK inhibitors had significantly lower levels of anti-spike immunoglobulin G antibodies (P = .024) than healthy individuals.
