Newborn vitamin K injection refusals in the United States more than doubled between 2017 and 2025, rising from 3.1 per cent to 6.8 per cent, according to research published in JAMA Pediatrics.
The study found that infants who missed the injection faced a 47 per cent higher risk of bleeding events during their first six months. The risk of brain bleeding also more than doubled without the preventive shot.
Vitamin K has been standard newborn care since the early 1960s. The American Academy of Pediatrics continues to urge parents to consult paediatricians about its preventive benefits as doctors warn of potentially serious complications from rising refusal rates.
