Vitamin K Shot Refusal Linked to Fatal Bleeding in Newborns Across U.S.

They entered the world with piercing cries, passed newborn screening tests, and some even made it to their 2-week wellness visits without concern. Then, without warning, their systems began to shut down.

In Maryland, a 7-week-old boy developed sudden seizures. In Alabama, an 11-pound girl stopped breathing for 20 seconds at a time. In Kentucky, a baby boy vomited before becoming lethargic. In Texas, a brown-haired girl, not yet 2 weeks old, bled around her belly button. Desperate to save them, doctors inserted tubes into their airways, hooked them up to IVs, and ordered blood transfusions. They spent half an hour trying to resuscitate one boy until his parents told them they could stop. They shaved another boy’s soft locks to embed a needle directly into his skull to reduce pressure in his brain. None of it was enough.

At the morgue, the babies arrived with their diapers, blankets, and hospital ID bracelets still wrapped around their tiny ankles. The pathologists’ findings were like those typically seen in ailing adults—not newborns. The bleeding resembled strokes, and brain tissue loss mirrored damage from radiation treatment. Their autopsies, conducted over the last several years, all reached the same conclusion: The deaths were caused, in whole or in part, by a rare but potentially fatal condition known as vitamin K deficiency bleeding.

In almost every case, the babies’ deaths could have been prevented with a long-standard vitamin K shot given at birth. Yet across the country, families—first in small numbers, now in growing droves—are declining the single, inexpensive injection designed to help newborns’ blood clot.

Many parents refuse the shot out of well-meaning but misguided caution, prioritizing perceived protection from medical intervention over scientifically proven safeguards. This trend is exacerbated by a flood of false information circulating on social media, despite the vitamin K shot not being a vaccine. It has been swept up in the same post-pandemic tide that has reduced key childhood vaccinations, including those for measles and whooping cough.

The vitamin K shot is one of three main interventions—alongside the hepatitis B vaccine and antibiotic eye ointment—that newborns typically receive before leaving the hospital. Leading American institutions and the World Health Organization (WHO) recommend it. In December, the Centers for Disease Control and Prevention (CDC) stopped recommending that all newborns receive the hepatitis B vaccine, which has effectively combated a virus that can lead to lifelong infections and liver cancer. A federal judge in March temporarily blocked the revised childhood vaccination schedule that included this change.

Despite the proven benefits of the vitamin K shot, misinformation and skepticism have led to a rise in refusals, putting newborns at risk of preventable, life-threatening conditions.
