Parents Increasingly Reject Vitamin K Shots for Newborns, Hospitals Report

Key Points:

• A rising number of U.S. families are declining the standard vitamin K injection given to newborns, leading to preventable cases of vitamin K deficiency bleeding, a rare but potentially fatal condition causing severe bleeding and brain damage in infants.
• Despite decades of evidence that the vitamin K shot is safe and effective in preventing this bleeding disorder, misinformation on social media and distrust in medical interventions have fueled parental refusal, with refusal rates more than doubling in some hospitals since the pandemic.
• The Centers for Disease Control and Prevention and major medical organizations continue to recommend the vitamin K shot, but lack of systematic tracking and reporting of vitamin K refusal and related complications hampers public health responses and data collection.
• Medical professionals warn that vitamin K deficiency bleeding, which can cause strokes and brain tissue loss in newborns, is often underrecognized, and that refusal of the shot significantly increases the risk of life-threatening bleeding and death.
• Efforts to educate families and counter misinformation have had limited success, and some hospitals report multiple deaths linked to vitamin K refusal, underscoring the urgent need for better data monitoring and public health outreach.
