“…Patients with GCA are more severely affected by SARS-CoV-2 if elderly, male, suffering from multiple comorbidities, or on more than 10 mg prednisolone 16 . Following vaccination, an increased risk for GCA has been implied with a reporting odds ratio (OR) of 2.7 (95% CI: 2.3–3.2) 17 . This was, however, not significant if compared to use of influenza vaccines (0.5, 95% CI: 0.4–0.7).…”

“…Some cases of GCA following SARS-CoV-2 vaccination have also been described. Using VigiBase analysis (26,246,383 reports until 30 June 2021 with 1,295,482 reports concerning COVID-19 vaccines), Mettler et al [34] reported 147 cases of GCA, 290 cases of polymyalgia rheumatica (PMR) and 9 GCA with PMR cases, which resulted in an increased risk of GCA (ROR [reporting odds ratio] = 2.7 [95% CI: 2.3; 3.2]) and PMR (ROR = 2.3 [95% CI: 2.0; 2.6]) following SARS-CoV-2 vaccination, whereas it was not the case after influenza vaccination for GCA (ROR = 0.5; [95% CI: 0.4; 0.7]) and PMR (ROR = 0.2; [95% CI: 0.2; 0.2]). Median (IQR) time from vaccination to first symptoms onset was 4 (1-14) days.…”

“…COVID-19 vaccination is a global effort. In Spain, over 79% of the population is fully vaccinated and, although the benefits obtained from immunization clearly outweigh any potential risks, we have noticed a few case reports of autoimmune diseases possibly triggered by the vaccine in the last year [ 1 , 2 ].…”

“…Although they seem to be rare events, the true scope of this issue is still uncertain. Recently, a pharmacovigilance study was published revealing a higher incidence of both giant GCA and polymyalgia rheumatica (PMR) following mRNA vaccines supporting a causal relationship [ 1 ]. Since the possibility of incidental co-existence in the present case cannot be discarded, further studies should be undertaken to better understand the potential uncommon effects of these vaccines.…”
