More parents are declining vitamin K shots for newborns, putting more babies at risk of bleeding: Study

Key Points:

• Refusals of the vitamin K shot for newborns, once rare, have significantly increased, with some hospitals reporting up to half of babies leaving without the injection, according to pediatricians and new research from the Children's Hospital of Philadelphia.
• Analysis of over 5.2 million health records showed that from 2017 to 2025, the percentage of babies not receiving vitamin K at birth more than doubled from 3.1% to 6.8%, raising concerns about increased risk of severe bleeding and related complications.
• Vitamin K is critical for blood clotting in newborns, preventing vitamin K deficiency bleeding (VKDB), which can cause life-threatening brain bleeds, permanent brain damage, and death; babies without the shot have a 47% higher risk of bleeding events in their first six months.
• Some parents refuse the shot due to misinformation, confusion with vaccines, concerns about preservatives, or misunderstanding of FDA black box warnings, despite the vitamin K injection being a safe, long-established preventive measure.
• Medical experts urge parents to consult healthcare providers and emphasize that the vitamin K shot is a simple, effective protection against serious bleeding, likening it to wearing a seatbelt to prevent injury.
