Newborn vitamin K administration misinformation and refusal

Medical professionals have warned of rising social media misinformation regarding vitamin K administration for newborns. Claims on platforms such as TikTok and X have suggested that the vitamin K shot thickens blood to a degree that prevents stem cells from repairing birth-related trauma, a claim experts state lacks scientific evidence.

Following these warnings, research published in JAMA and JAMA Pediatrics has documented a significant increase in parents declining the vitamin K injection. Analysis of over 5 million health records found that the percentage of babies not receiving the shot more than doubled between 2017 and 2025, rising from 3.1% to 6.8%.

A separate analysis of more than 11 million infants revealed that vitamin K deficiency bleeding increased by 347% during that same period. According to the CDC, babies who forgo the shot are 81 times more likely to develop a bleeding disorder. Clinical data indicates that infants who do not receive the injection face a 47% higher risk of bleeding within their first six months and more than double the risk of intracranial hemorrhaging.

Medical professionals report that some parents decline the injection due to concerns regarding black box warnings or by mistakenly categorizing the shot as a vaccine. While vitamin K can be administered orally, experts emphasize that the injection is standard practice to prevent life-threatening complications.

In a related case in New Braunfels, Texas, a family filed a complaint with the Texas Medical Board alleging that an emergency room doctor failed to recognize vitamin K deficiency bleeding in their 11-day-old daughter. The infant had experienced persistent bleeding from her umbilical cord stump after her parents had opted for oral drops instead of the standard injection at birth.
