Abstract
Despite the significant reduction of both morbidity and mortality after the introduction of many vaccines against COVID‐19, recent reports indicated a worsening skin conditions in particular patients with psoriasis. We extracted the data of 51 patients from 19 papers. The mean age was 56.9 (SD = 16.2) years, with a male prevalence 45%. Of the 51 cases, vaccine types at which psoriasis flare occurred were as the following: Pfizer vaccine (30), AstraZeneca (9), Moderna (8), Coronavac (2) Covishield (1), and Covaxin (1). Exacerbation was common in the second dose of Pfizer, AstraZeneca, Moderna, and Covishield vaccines. Moreover, the onset of psoriasis exacerbation was shorter after the second dose of Pfizer (mean = 12.8 [SD = 15.2]) and AstraZeneca (mean = 7.4 [SD = 3.6]) rather than the first dose of both vaccines, respectively (mean = 19.2 [SD = 21.3]) and (mean = 18.5 [SD = 10.7]).

1. INTRODUCTION
A close attention toward many skin conditions was devoted among the dermatologic society during the COIVD‐19 era. Not only for its cutaneous manifestations' in previously healthy individuals but also the outcomes of many patients with chronic skin conditions. 1 Despite the significant reduction of both morbidity and mortality after the introduction of many vaccines against COVID‐19, recent reports indicated a worsening skin conditions in particular patients with psoriasis. 2 , 3 , 4 In this report, we aimed to study the characteristics of psoriasis patients who experienced exacerbation of their comorbidity in relation to vaccine types.
2. METHOD
To get the relevant papers, a PRISMA guided search was conducted in five databases: PubMed (n = 43), Web of Science (n = 39), Virtual Health Library (n = 62), Scopus (n = 85), and Google Scholar (n = 889). We used the term “(psoriasis) AND (‘COVID‐19 vaccination’ OR ‘COVID 19 vaccination’ OR ‘COVID‐19 vaccine’ OR ‘COVID 19 vaccine’)” till June 18, 2022. We included all papers that reported exacerbation of psoriasis patients after COVID‐19 vaccination. We excluded reviews and conference abstracts. We extracted all the relevant information related to COVID‐19 vaccination (Table 1).

3. RESULTS
We extracted the data of 51 patients from 19 papers (Table 1 and supplementary file, Data S1). The mean age was 56.9 (SD = 16.2) years, with a male prevalence 45%. The type of psoriasis was plaque (33), pustular (4), vulgaris (2), palmoplanter (1), and not reported (11). Of the 51 cases, vaccine types at which psoriasis flare occurred were as the following: Pfizer (30), followed by AstraZeneca (9), Moderna (8), Coronavac (2), Covishield (1), and Covaxin (1). Exacerbation was common in the second dose of Pfizer, AstraZeneca, Moderna, and Covishield vaccines (Figure 1). Moreover, the onset of psoriasis exacerbation was shorter after the second dose of Pfizer (mean = 12.8 [SD = 15.2]) and AstraZeneca (mean = 7.4 [SD = 3.6]) rather than the first dose of both vaccines, respectively (mean = 19.2 [SD = 21.3]) and (mean = 18.5 [SD = 10.7]).

4. DISCUSSION
COVID‐19 vaccines exhibit several cutaneous manifestations including swelling erythema, rash, and urticaria. However, flaring of certain dermatological diseases occurred after vaccination as well. 5 Herein, we found that exacerbation of psoriasis condition after COVID‐19 vaccination mainly occurs after the second dose of four of the reported six vaccines as only one report indicated Covaxin induced‐psoriasis exacerbation after the first dose in addition to the similar prevalence of the first and the second dose in Coronavac‐induced psoriasis. It is worth noting that the psoriasis flare was reported after a mean of 12.8 and 7.4 days of Pfizer and AstraZeneca second dose, which is much lower than the onset of psoriasis flare in the first dose of both vaccines, which occurred after nearly 19 days in both vaccines.
Our understanding regarding the possible mechanisms for psoriasis exacerbation after COVID‐19 vaccines are still under investigation. However, certain hypotheses may be close to answer our concerns regarding this phenomenon such as the immunity suppression that was derived from the immunosuppressant drugs for the psoriasis treatment together with the activation of dendritic cells and the associated increase of the expressed cytokines which play a significant role in psoriasis development. 6
Currently, there are no specific guidelines about the best therapeutic modality for psoriasis flare after COVID‐19 vaccination. Despite that immunosuppressants—in particular steroids (either topical or systemic)—constituted the backbone of therapy in many of our included cases (Table 1). 4 , 7 , 8
Vaccination against COVID‐19 is of extreme importance in both the healthy individuals and those with comorbid conditions especially psoriasis. However, close monitoring of psoriasis patients after COVID‐19 vaccination is recommended for the avoidance of psoriasis exacerbation despite being a rare entity. Moreover, increasing the knowledge about the safety and efficacy of COVID‐19 vaccination in patients with psoriasis is remarkably needed.
