After treating a 16-year-old girl for agonising lesions in her genitals, they suspect her recent jab could be the only cause.
The teenager was not sexually active and had been given her second Pfizer Covid vaccine dose days before coming to hospital.
Docs said the young woman had developed agonising “sores” in her vaginal area alongside a fever, fatigue and muscle aches within 24 hours of having the US-made jab.
Two days later she went to the emergency room and, although given antibiotics, did not improve.
The lesions in her vulva had a “necrotic” flesh-rotting ring and were leaking fluid. They were “exquisitely painful” and prevented her from using the toilet or walking.
Her labia were also swollen, according to the report in the Journal of Pediatric and Adolescent Gynecology.
Tests showed the teen did not have Covid or herpes, causing medics to consider the jab she’d recently had.
But if there is a link, the complication would be extremely rare.
The girl was diagnosed with “vulvar aphthous ulcers”, or Lipschütz ulcers, which is thought to be triggered by an immune response to a viral infection.
