Disease activity and humoral response in patients with inflammatory rheumatic diseases after two doses of the Pfizer mRNA vaccine against SARS-CoV-2

Abstract: BackgroundThe registration trials of messenger RNA (mRNA) vaccines against SARS-CoV-2 did not address patients with inflammatory rheumatic diseases (IRD).ObjectiveTo assess the humoral response after two doses of mRNA vaccine against SARS-CoV-2, in patients with IRD treated with immunomodulating drugs and the impact on IRD activity.MethodsConsecutive patients treated at the rheumatology institute, who received their first SARS-CoV-2 (Pfizer) vaccine, were recruited to the study, at their routine visit. They we… Show more

“…Despite this, vaccine hesitancy remains an alarming problem worldwide. Data regarding COVID-19 vaccine efficacy and adverse events (AE) in patients with autoimmune and inflammatory rheumatic diseases (AIIRD) have been published recently although these mostly include the mRNA vaccines (Pfizer-BioNTech and Moderna) and the ChAdOx1 nCoV-19/AZD1222 (Oxford/AstraZeneca) [6][7][8][9]. Many other vaccines are being administered worldwide and data in AIIRD population are limited.…”

“…In particular, BNT162b2 elicited strong antibody responses; one week after the second dose, the geometric mean of the 50% neutralization titers of SARS-CoV-2 serum was up to 3.3-fold higher than that observed in samples from individuals who recovered from COVID-19 and also showed poly-specific cellular immunity [ 71 ]. In contrast, most patients on maintenance hemodialysis developed a substantial humoral response after administration of the BNT162b2 vaccine and it was significantly lower than in the control [ 72 ], whereas 86% of patients with inflammatory rheumatic diseases developed a humoral response following the administration of the second dose of the BNT162b2 vaccine [ 73 ].…”

“…There is few research hitherto about MG course after COVID-19 vaccination. Several studies investigating the safety of SARS-CoV-2 mRNA vaccines in patients with stable RMDs revealed minor side effects and no distinct impact on RMD activity (109,110). A recent multicenter study reported no evidence of significant disease flares, but the occurrence of herpes zoster after BNT162b2 mRNA vaccination in subjects with low and even no IST is worth investigating (80).…”
