Time Course of Antispike Antibody Titer after Administration of BNT162b2 mRNA COVID-19 Vaccine in a Patient with Rheumatoid Arthritis on Methotrexate

Figure 1

Anti-S antibody titer after primary vaccination and before and after booster vaccination. Anti-S antibody titer levels are shown for the RA patient taking MTX (yellow circle), poor responder HCW (blue circle), and good responder HCW (black circle). The time course of the titers of the RA patient and poor HCW are illustrated by solid lines. The measured values of good responder HCWs are presented in Supplementary Table S1. Overlapping circles are displayed as horizontal shifts. Anti-S antibody: antispike antibody, RA: rheumatoid arthritis. HCW: healthcare worker, MTX: methotrexate.
