Clinicopathological features of cutaneous reactions after mRNA‐based COVID‐19 vaccines

Abstract: Background Cutaneous reactions, mostly on injection site after mRNA‐based COVID‐19 vaccines, have been reported but not with detailed histopathological characterization. Objectives Characterization and classification of these reactions in a clinical and pathological point of view. Methods Monocentric case series of 11 patients with cutaneous manifestations, clinically and histologically characterized after COVID‐19 vaccination. Results From January to June 2021, we recorded 11 cutaneous reactions to mRNA COVID… Show more

“…In the study by Català et al, the ‘COVID arm’ was much more common in females (95.4%) and is more likely to be associated with systemic symptoms (64.6%) than other post-vaccination eruptions [ 2 ]. It can manifest as a solitary pink patch or plaque associated with erythema, induration, pruritus, and/or tenderness ( Figure 1 ) [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. Severe reactions with lesion sizes of >10 cm have been reported [ 9 ].…”

“…The former is a potential contraindication to the second dose. One hundred twenty-eight cases of urticarial eruption were reported in 12 studies [ 1 , 2 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ], of which 57 (44.5%) were after BNT162b2, 47 (36.7%) after mRNA-1273, and 24 (18.8%) after AZD1222 vaccination ( Figure 2 ). Of these cases, 11 were labeled by the CDC as part of an anaphylaxis reaction and submitted to the Vaccine Adverse Event Reporting System (VAERS) [ 18 ].…”
