Pityriasis rosea (PR), PR-like eruptions (PR-LE), and herpes zoster have been frequently reported during the COVID-19 pandemic and following COVID-19 vaccination. PR is a self-limiting exanthematous disease and herpes zoster is a treatable condition; therefore, their occurrence does not require discontinuation of the vaccination schedule. PR-LE is a hypersensitivity reaction and is, therefore, less predictable in its course. In the case of a booster dose, the clinical manifestation may not recur, may be different from PR-LE, or may present with systemic symptoms; however, in the case of PR-LE, the possibility of mild and predominantly cutaneous adverse events should not discourage all eligible candidates from receiving and completing the COVID-19 vaccination program, as such adverse reactions represent a small risk considering the possible severe and fatal outcome of COVID-19. We emphasize the relevance of looking for any viral reactivation in patients infected with SARS-CoV-2 who have skin eruptions. The search for viral reactivations could be useful not only for distinguishing between PR and PR-LE but also because viral reactivations may contribute to a patient's systemic inflammation and influence the course of the disease.
