Papular skin reaction after the administration of the Ad26Cov2‐S vaccine.

The cutaneous lesions which appeared on the skin of this patient may be presumptively attributed to the administration of the Ad26Cov2-S vaccine; indeed, we may hypothesize that they might have been the expression of a delayed hypersensitivity reaction or of a non-immune-mediated inflammatory event. Over the last months, the scientific community has made strenuous efforts to develop new vaccine formulations to tackle the global health issues brought by COVID-19. All in all, the Ad26.COV2.S vaccine may be linked to the onset of widespread cutaneous reactions a couple of days after its administration, however, such reactions do not appear to be common.
