A college student who suffered severe burns has now recovered after becoming the first patient in the world to receive an experimental treatment.
In December 2025, Kaitlin Jeffrey — an 18-year-old student at Western University in Ontario, Canada — suffered severe burns to her face and neck during a fire at a fraternity house. The incident sent five people, including Jeffrey, to the hospital.
Jeffrey was transferred to Hamilton General Hospital's regional burn center where doctors at Hamilton Health Sciences (HHS) determined she could receive an innovative treatment to speed up her healing process.

The new treatment involves using exosomes, which are tiny particles released by cells that help coordinate healing, tissue repair and reduce inflammation.
According to medical experts, the particles are collected and injected into the injured areas to accelerate healing. This is said to be a better approach than the typical skin grafting process, which can result in scarring and a “patch-like appearance.”

"My vision for Kaitlin was to avoid skin graft surgery to her face and neck at any cost," Dr. Marc Jeschke, vice president of research and innovation at HHS and medical director of the hospital's regional burn program, said in a release.
“You can do the best graft on the planet, but you won't return the skin to normal. And, for a young person, a skin graft to the face and neck can be absolutely devastating,” he said.

After approval from Jeffrey's parents, Jeschke and his team became the first in the world to perform the treatment on a burn patient. She reportedly received two treatments, days apart, using one trillion exosomes that were sourced from the United States.
Doctors called the results "absolutely remarkable." Jeffrey, originally from Toronto, is thrilled about her recovery and expressed her gratitude to the entire burn center.
She told the hospital that she hopes her case will lead to more options being available for other patients like herself, even outside of Canada.

“It's honestly a miracle,” she said of the treatment. “Being injured in the fire has also had a deep impact on my mental health, and it's something I'm continuing to deal with. But having such good results, particularly to my face, is helping me move forward.”
“Like Dr. Jeschke, my family and I would love to see exosome therapy become the standard of care for patients like myself in Canada, so that when horrific things happen, it doesn't change people's lives forever,” she added.
