A Child's Fight Against 22 Life-Threatening Allergies
For 10-year-old Yann Jennings, a simple slice of birthday cake or a sleepover with friends could be deadly. He has 22 potentially life-threatening allergies that make everyday activities extremely dangerous. His mother, Katie Hutt, explains that Yann is allergic to dairy, wheat, peanuts, tree nuts, coconut, seafood, eggs, kiwi, sesame, nutmeg, quinoa, soy, pulses, rye, oats, barley, tuna, red fish, pollen, flaxseed, pumpkin seed, buckwheat, and even animals like cats, dogs, and horses.
Katie, a former lawyer who left her job to care for Yann, recalls the constant fear they faced. “He was allergic to airborne particles, trace amounts, and contact. Any of these could trigger anaphylactic shock.” The family avoided cafes, flights, and public places where Yann might come into contact with something he couldn’t tolerate. Every day felt like playing with fire.
Yann’s journey with allergies began early. As a baby, he had severe reactions to vaccinations and developed eczema all over his body. At six months old, blood tests revealed he was allergic to milk, peanuts, and eggs. “I’m allergic to milk too, but it doesn’t kill me. Yann’s allergies were so severe that even the smallest exposure could be fatal.”
Katie learned about managing allergies through Facebook groups, as there was little support from medical professionals. “Doctors gave us a leaflet and that was it. We were on our own.” She quickly realized the importance of carrying two EpiPens at all times, which can deliver emergency doses of adrenaline during anaphylactic shock.
Yann’s first experience with anaphylaxis happened when he was just one year old. “I put coconut cream in a vegetable puree I was making. That was the first time we had to use an EpiPen. If I hadn’t had it, he would have died.” The incident left the family shaken, and it highlighted the lack of awareness about the severity of allergies.
As Yann grew older, his allergies became more complex. He would panic at the sight of food, and even simple outings required careful planning. “We spent so much time outdoors because it was safer. Everything from nursery to soft play was off limits.” At home, they kept windows open and used a special bib that read “Don’t feed me” to protect him from accidental exposure.
In March 2024, the UK government announced new measures to improve allergy management in schools. This includes stocking EpiPens and providing training for teachers. However, Katie points out that these changes do not apply to Wales, where she lives. “We have to ensure Yann always has his own EpiPens,” she says.
Despite the challenges, hope came from an unexpected place—Facebook. In 2022, the family learned about a pioneering allergy elimination program in California. Yann began treatment in August 2024, receiving microdoses of various food proteins under the guidance of specialists. “We dose him morning and night at home and visit the clinic every 12 weeks for adjustments,” Katie explains.
The treatment has allowed Yann to fly with British Airways, which has invested in allergy training for staff. While the process is expensive, with flights and accommodations costing thousands, the family has managed with help from a GoFundMe campaign and by remortgaging their home.
Katie believes this treatment will give Yann a chance to live a normal life. “Within 18 months, he should be allergy-free and able to go to high school without fear.” For years, the family has lived in survival mode, constantly worried about Yann’s safety. Now, they are beginning to see a future filled with hope.
With most allergy-related deaths occurring in teenagers and young adults, Katie wants Yann to be cured before he starts high school. “This treatment aims to help his body metabolize things that once killed him. For the first time, the fear is subsiding, and we’re looking to the future with optimism.”
A Department of Health and Social Care spokesperson said they are working with experts to improve allergy care and support. Meanwhile, Katie continues to advocate for better education and resources for families dealing with severe allergies. “We need mandatory training in schools and the catering industry. No child should live in constant fear.”
