Refusal of Newborn Vitamin K Injections Rises Sharply Over Six Months
The share of parents declining the routine vitamin K shot for newborns increased from 5.2% to 8.1% between December 2025 and June 2026, raising concerns about preventable bleeding disorders.
The proportion of parents who decline the vitamin K injection for newborns rose sharply, climbing from 5.2% in December 2025 to 8.1% in June 2026, a 57% increase over six months, according to health data. The injection, administered within the first day of life, has been standard practice since the 1960s and is credited with virtually eliminating vitamin K deficiency bleeding in the United States.
Vitamin K is essential for blood clotting, and newborns are born with low levels, making them vulnerable to severe bleeding that can cause long-term neurological damage or death. Researchers at the American Academy of Neurology reported that among infants who develop the condition, about 14% die, roughly 40% suffer lasting neurological impairments, and 63% experience brain hemorrhages.
"We’re trying really hard to keep little babies alive," said Dr. Nia Heard-Garris, a pediatric physician-scientist at Lurie Children’s Hospital in Chicago, referring to the growing number of refusals.
"There may be a growing perception among parents that vitamin K is unnecessary," said Dr. Kristan Scott of the Children’s Hospital of Philadelphia, who led a NIH-supported study. "Unfortunately, opting out of vitamin K for a newborn is akin to gambling with a child’s health, forgoing a straightforward and safe measure that effectively prevents severe complications."
The trend reflects broader vaccine hesitancy, with some parents questioning the necessity of the injection despite its established safety and effectiveness.
