Kim Blumenthal, an allergist and epidemiologist and professor of medicine at Harvard medical school. “We do have more cases that are being reported in women, but that could be that women are more likely to tell you,” said Dr. The rash also seems to be more common in women, but it’s hard to tell because the first people who got the Modena vaccine were health care workers, the majority of whom tend to be women. “It doesn’t mean you should get Pfizer instead of Moderna," she said. The specific reaction has occurred only in people who’ve gotten the Moderna vaccine, not the Pfizer vaccine, Freeman said. A small number of rash reactions were reported in Moderna’s clinical trials. “It’s temporarily dramatic, but it will go away” within 24 hours to a week, Freeman said. It always occurs on the arm where the shot was given. The rash is red, sometimes itchy and painful to the touch, and can be as much five or six inches across. So far, there are only 14 examples in the registry, but she thinks there are more that haven’t been reported.ĬOVID-19 vaccine reactions can be reported on the CDC's V-safe page.ĭermatologists and allergists are studying the side effect, which they’ve tentatively dubbed "delayed cutaneous hypersensitivity." Laypeople are calling it "COVID arm."
“We want to reassure people that this is a known phenomenon," she said. "Having a big red splotch on your arm for a couple of days may not be fun but the reality is there's no need to panic and no reason not to get your second shot."įreeman is the principal investigator in the global COVID-19 dermatological registry, which is collecting case reports from doctors of people experiencing COVID-19 responses. Esther Freeman, director of global health dermatology at Massachusetts General Hospital. There is no indication the reaction is anything but a topical – and brief – response as the body’s immune system goes to work, said Dr. Aside from sometimes being itchy, it doesn't appear to be dangerous, and people who get it should not hesitate to get their second dose of the vaccine, doctors say. These medications could be the possible inciting factor for many of the observed rashes however, it is important to continue to note cutaneous lesions in COVID-positive patients as we continue to refine our understanding of the virus and its manifestations in order to make a correct and swift diagnosis for future patients.Watch Video: COVID-19 symptoms versus flu symptomsĪn angry red rash being called “COVID arm” is a harmless but annoying response in some people who get the Moderna vaccine. Many of the lesions in COVID-positive patients have been described in critically ill patients who are receiving advanced care and taking a multitude of new medications. One of the biggest challenges in describing cutaneous lesions is uncovering the inciting factor. Damage can then lead to disease processes such as urticarial vasculitis, central nervous system vasculopathies, and varicella-like exanthems. COVID-19, like many other viruses, can gain entry to the endothelial cells via binding to heparan sulfate. 6 COVID-19–associated vasculopathy occurs inside the blood vessels via endothelial cell inflammation, apoptosis, dysfunction, and immune complex deposition. The connection between COVID-19 and vascular damage has been well established. Laboratory findings can include hypocomplementemia, especially in cases linked to connective tissue diseases.
Although the lesions may be asymptomatic, they can be accompanied by a burning sensation, pain, and fever. Clinically, urticarial vasculitis is characterized by the appearance of urticarial lesions similar to wheals, with individual lesions present >24 hours. 5 Many causes of urticarial vasculitis exist, the most frequent of which are drug reactions, viruses, and autoimmune diseases. Urticarial vasculitis is believed to be a type III hypersensitivity reaction with immune complex depositions and is one of the clinical expressions of leukocytoclastic vasculitis. 3 Many cutaneous manifestations have been described in association with COVID-19, which include but are not limited to morbilliform rash, varicelliform eruption, urticarial formation, acral lesions (COVID toes), and livedoid eruptions. Patients with a rash and COVID-19 most often develop a fever, followed by a cough, shortness of breath, and fatigue. 2 However, approximately 25% of patients with cutaneous manifestations will develop them either before other symptoms arise or as the independent symptom of their infection.

Skin lesions that appear in patients with COVID-19 typically develop after other coronavirus symptoms appear. 2 These 58 cases represented an astounding 52% of dermatology consultations during this same time frame. Giavedoni et al reported cutaneous manifestations of COVID-19 appearing in 58 of 2761 (2.1%) patients.
