Chrissy Teigen Turned Her Son's T1D Diagnosis Into a Sanofi Deal
Her six-year-old ended up in the ER three days before the family learned 'Type 1 diabetes' for the first time. One year later, he has an insulin pump, a glucose monitor, and a Sanofi spokesperson deal alongside his mother.
Beam Me Over ↓
Chrissy Teigen's son Miles was doubled over in pain at football day camp last summer when the camp called and asked her to come get him ... the ER thought appendix trouble, the blood tests kept coming back with something else, and three days later the family that "knew nothing about type 1 diabetes" had to know everything, fast.
Sanofi named Teigen, and Miles, as spokespersons for its Screen For Type 1 movement on T1D Day, April 15, 2025. The campaign is in its second year. Its ask is simple: get a blood test that can detect T1D-related autoantibodies before any symptom appears, before any emergency, before a child ends up in a hospital bed.
Three Days, Then Everything Changed
The day camp flagged a shigella outbreak and told Teigen to pick Miles up. He was in too much pain. The ER ruled out a shigella case and then started wondering about his appendix. After three days and a string of blood tests, doctors told the family it was Type 1 diabetes.
Teigen called it "just so shocking." She said it felt like a "gut punch." She admitted she had friends with T1D as a child and assumed it would be manageable, so the reality of what comes next landed harder than she expected.
The first week: trips to Children's Hospital, practicing insulin injections on fruit and on themselves before attempting them on Miles. John Legend usually handles Miles's insulin prep. When he was traveling, Teigen FaceTimed him to make sure she was doing it correctly. Miles, now 7, wears a glucose monitor and an insulin pump at all times.
Why Pharma Picked the Worried Parent
The earlier Screen For Type 1 roster leaned athlete: Usher, ultramarathoner Robin Arzón, and broadcaster Adam Schefter, all of whom have T1D themselves. Sanofi was reaching people already inside the diabetes community with those picks.
Teigen is a different play. She reaches parents who have never thought about T1D, whose children have never been flagged for any risk factor. Her story is not "I have this condition and I manage it." Her story is "we had no idea, then our child was in the ER, and by the time we understood what was happening it was already a crisis."
Nadia Fontaine, head of Sanofi's US autoimmune T1D franchise, put the campaign's core argument plainly in the April announcement: "It's unacceptable that many people are still finding out" about a T1D diagnosis only after serious complications force the issue.
That is the gap Sanofi is selling against: per the company, 40% of Americans with T1D do not know they have it until a life-threatening event. About 64,000 Americans are diagnosed each year. A single blood test can find the autoantibodies that signal T1D risk before a single symptom shows up.
The Kid Is Also a Spokesperson
One detail the Sanofi press materials mention: Miles is also a spokesperson on the campaign, not just background color in his mother's story. He was inspired, per Fortune's reporting, after meeting Nick Jonas at the Paris Olympics last summer. Jonas has had T1D since he was 13 and has been public about it for years. Miles reportedly left that meeting wanting to be a role model for other kids with the condition.
The choice to put a 6-year-old in a corporate spokesperson role, even alongside his parent, is unusual in pharma marketing. It raises questions that the campaign materials do not answer, about consent and commercial disclosure rules for minors. Sanofi disclosed that both Teigen and other social media participants in the campaign are paid.
What the Authenticity Buys
Paid celebrity campaigns get written off as mercenary all the time, and sometimes that is exactly what they are. The Teigen arrangement is harder to dismiss because the crisis happened before the deal. Sanofi did not manufacture a health scare; it found a parent whose scare was already public and built a campaign around it. The emotional rawness in Teigen's account of the first week, the FaceTime calls to get the insulin dose right, the glucose monitor alerts on her phone, those are details you do not reach for when you are just collecting a check.
Whether that authenticity survives the commercial wrapper is the question pharma brand managers are always asking. In Teigen's case, the answer is probably yes, at least for the audience that most needs to hear it: parents who think T1D is something that happens to other families, in other ERs, with other kids. It happened to hers.
