US Infant Bleeding Cases Surge as Parents Refuse Routine Vitamin K Shots

Life-threatening bleeding cases among infants in the United States have surged dramatically over the past year as a growing number of parents refuse to administer a critical vitamin K injection at birth, according to a new study published in JAMA Pediatrics.

As reported by the Washington Post, this alarming trend is closely linked to a broader decline in public trust within the American healthcare system. Vitamin K is essential for blood clotting. Newborns enter the world with insufficient amounts of the vitamin, breast milk does not provide it adequately, and their digestive systems are not yet mature enough to produce it independently.

Dr. Elizabeth Wolf, a professor of pediatrics at the University of Virginia and one of the study's co-authors, explained that vitamin deficiency exposes infants to the severe risk of uncontrolled bleeding and stroke. "Twenty percent of infants who suffer a stroke as a result of this deficiency will die, and forty percent of survivors will suffer permanent neurological problems," Wolf warned.

Data indicates that the number of annual bleeding cases gradually increased from 189 to 903 between 2017 and 2024. However, in 2025 a dramatic spike occurred, nearly doubling the figure to 1,764 cases. Concurrently, the proportion of infants receiving the injection dropped from 98 percent to 95 percent.

Professor Stephen Wolf, another co-author of the study, noted that generations have passed without witnessing such a surge in complications, describing it as a frustrating regression in public health advancements. A separate study conducted by the Children's Hospital of Philadelphia confirmed the trend, establishing a clear link between vaccine-like skepticism and the refusal of the routine birth injection.

Medical experts and Democratic lawmakers point an accusing finger at the administration and figures like Robert F. Kennedy Jr., arguing that skepticism is worsening the public health crisis. Conversely, officials within the Department of Health attribute the drop in trust to rigid guidelines and contradictory messaging during the COVID-19 pandemic under the previous administration.

Physicians emphasize that the vitamin K injection is not a vaccine, though many parents confuse the routine procedure due to how it is administered. Despite the availability of oral vitamin K drops, experts note that oral administration is significantly less effective. Nevertheless, study authors suggest considering oral drops as a "harm reduction" approach for parents who adamantly refuse the intramuscular injection.
