“…Only two case reports [8,9] of delayed cutaneous reactions with the ChAdOx1 nCoV-19 vaccine were found, analogous to the ones manifested by the present infant lesions. All lesions observed in the breastfeeding infant were similar to previous descriptions of cutaneous reactions around the injection site in people had been vaccinated with other COVID-19 vaccines [10][11][12][13][14][15] and with a healthy neonate born from COVID-19-positive mother [16]. The authors state that this is a remarkable fact that deserves attention and discussion among healthcare professionals.…”
The ChAdOx1 nCoV-19 vector vaccine (Vaxzevria, AstraZeneca, Cambridge, UK) was developed at Oxford University and is considered safe for the administration in lactating mothers. Nevertheless, as a novel vaccine, there are gaps in the knowledge regarding possible adverse events in breastfeeding infants of vaccinated mothers. This case report provides first-time data on a possible delayed, cutaneous, adverse reaction in a breastfed, 16-month-old female infant after the first administration of the AstraZeneca vaccine to her 33-year-old mother. Even though, no clinical adverse effects were observed in the mother, her daughter had a 2-day rash in the lower extremities and face. The infant’s cutaneous rashes might be a coincidental event. However, all skin lesions were analogous to previous descriptions and photographs of dermatologic reactions, which resolved spontaneously with no medical intervention, in people who had been vaccinated with other COVID-19 vaccines. Our aim is that this short report contributes to the enhancement of parental awareness about the possibility of similar skin rashes in breastfed children when the mothers receive a vaccination and the importance of reporting those adverse reactions to the competent authorities.

“…In cases where the same sample was used for more than one study, all studies were reviewed to determine the extent to which there may be duplication in the reported outcomes between studies. The full text of selected studies was reviewed, and data on demographics, article type, number of reported cases with cutaneous involvement, vaccine, and rash type (morphology) were extracted from articles texts, tables, figures, and summarized through a descriptive table (Table 1)…”
To date, over 250 million people have been reportedly infected by COVID‐19 disease, which has spread across the globe and led to approximately 5.1 million fatalities. To prevent both COVID‐19 and viral transmission, DNA‐based/RNA‐based vaccines, non‐replicating viral vector vaccines, and inactivated vaccines have been recently developed. However, a precise clinical and histological characterization of SARS‐CoV‐2 vaccine‐related dermatological manifestations is still lacking. A systematic review of 229 articles was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines, in order to provide an extensive overview of SARS‐CoV‐2 vaccine‐related skin manifestations. Data on demographics, number of reported cases with cutaneous involvement, vaccine, and rash type (morphology) were extracted from articles and summarized. A total of 5941 SARS‐CoV‐2 vaccine‐related dermatological manifestations were gathered. Local injection‐site reactions were the most frequently observed, followed by rash/unspecified cutaneous eruption, urticarial rashes, angioedema, herpes zoster, morbilliform/maculopapular/erythematous macular eruption, pityriasis rosea and pityriasis rosea‐like eruptions, and other less common dermatological manifestations. Flares of pre‐existing dermatological conditions were also reported. Cutaneous adverse reactions following SARS‐CoV‐2 vaccine administration seem to be heterogeneous, rather infrequent, and not life‐threatening. Vaccinated patients should be monitored for skin manifestations, and dermatological evaluation should be offered, when needed.
“…The reaction lasts 2 to 11 days after onset, and generally will self-resolve or can be managed symptomatically with ice and antihistamines [ 78 ]. On rare occasions, there have been isolated reports of nodular and vesicular pruritic local reactions at the site of vaccination [ 100 , 101 ].…”

Purpose of Review
This review aims to evaluate the spectrum of cutaneous reactions after both SARS-CoV-2 infection and COVID-19 vaccination while simultaneously understanding the evolution of the field of dermatology in the face of an ongoing pandemic.
Recent Findings
The most commonly reported cutaneous reactions after COVID-19 infection in the literature to date include morbilliform or maculopapular rashes, chilblains, and urticaria. The incidence of cutaneous reactions after COVID-19 vaccination was 9% in larger cohort studies and more commonly occurred after mRNA-based COVID-19 vaccines than adenovirus vector vaccines. The most frequently reported cutaneous reactions after COVID-19 vaccines were delayed large local reactions, local injection site reactions, urticarial eruptions, and morbilliform eruptions.
Summary
With the ongoing pandemic, and continued development of new COVID-19 variants and vaccines, the landscape of cutaneous reactions continues to rapidly evolve. Dermatologists have an important role in evaluating skin manifestations of the virus, as well as discussion and promoting COVID-19 vaccination for their patients.
