A sudden increase in Stevens-Johnson syndrome (SJS)—a rare and potentially fatal skin disorder—may be triggered by COVID-19, increased vaccination rates, or a lowered threshold caused by vaccines or previous infection, according to a large case series recently published in Burns.

Researchers with the burns unit at Concord Repatriation General Hospital in Australia saw two to four cases of SJS, or toxic epidermal necrolysis (TEN), per year prior to COVID-19. In the first six months of 2022 alone, the same burn center observed a sevenfold rise in cases.
Of the 14 reported cases, five patients had COVID-19 a month before developing SJS/TEN, and three of 14 patients received a COVID-19 vaccine one month prior. Not a single case of SJS/TEN was reported in an unvaccinated individual.
Researchers said the rarity of the condition and presence of medications known to trigger the disease make the link difficult to prove, but the rapid rise in cases since the beginning of the pandemic and vaccine rollout is “alarming.”
SJS/TEN is a severe hypersensitivity condition where the skin develops rashes, blisters, and peels forming painful areas that resemble a severe hot water burn. Mucous membranes, including the eyes, genitalia, and mouth, are often affected or severely damaged, leading to sepsis, pneumonia, infection, or death.
Although SJS and TEN were once considered separate conditions, they are now part of the same disease—with SJS representing the less severe end of the disease spectrum and TEN representing the most severe.
Medications, including epilepsy medicines, antibiotics, and anti-inflammatory painkillers, are the chief cause of SJS/TEN, but certain viruses and vaccines can also cause the condition. Due to its potentially fatal nature, SJS/TEN is considered a medical emergency, and patients are treated in burn units.
Researchers’ 3 Theories for Sudden Rise in SJS/TEN Cases
The researchers proposed three theories for the sudden increase in SJS/TEN cases.
Virus-Induced
The first theory is that the SARS-CoV-2 virus may induce SJS/TEN by directly binding to receptors that trigger a T-cell-mediated response. Other viruses known to cause SJS/TEN include the herpes simplex virus, Epstein-Barr virus, and influenza.
Vaccine-Induced
A second theory is that COVID-19 vaccines may directly bind to cell receptors that trigger SJS/TEN and influence the body’s T-cell immune response initiating SJS/TEN. This T-cell response peaks at seven and 28 days post-vaccination, consistent with the observed cases.
Of the three cases attributed to vaccination in the study, two patients had received an mRNA vaccine, and one received a viral vector vaccine within a month of developing SJS/TEN. Researchers identified eight other cases of SJS following COVID-19 vaccination in published literature—four were associated with mRNA vaccines, three with viral vector vaccines like AstraZeneca and Johnson & Johnson, and one with a whole virus vaccine.
According to the U.S. Vaccine Adverse Event Reporting System (VAERS), 198 cases of SJS/TEN following COVID-19 vaccination were reported between Dec. 14, 2019, and June 23, 2023. Historically, VAERS has been shown to report fewer than 1 percent of actual vaccine adverse events, which means other cases of SJS/TEN may have occurred but were unreported.
Threshold Lowering
The third theory proposed by the authors is that developing a COVID-19 infection or receiving a vaccine “primes” the immune system, lowering the threshold for a drug to trigger SJS/TEN.
