Concerns Over Vitamin K Shot Refusals for Newborns

PHILADELPHIA — Dr. Tom Patterson, an Idaho pediatrician, recently experienced a troubling trend at his hospital: many newborns were not receiving vitamin K shots, a preventive measure used for decades to avert dangerous bleeding. On one occasion, half of the infants he examined didn’t get the shot, and on another day, over a quarter were left unprotected due to parental refusals.

“It’s alarming to see such a simple intervention, one that’s been in place since 1961, being declined,” Patterson reflected. “Looking at an innocent child in that situation feels incredibly concerning.” With nearly three decades of experience in pediatrics, he is not alone in this sentiment; many doctors nationwide are growing increasingly worried about the rising skepticism surrounding established medical practices, a trend often tied to an increasing mistrust in science.

A recent study published in the Journal of the American Medical Association reported a near doubling of vitamin K refusal rates from 2017 to 2024, jumping from 2.9% to 5.2% among more than 5 million births. Further data indicates that parents who opt out of vitamin K shots are also more likely to decline other essential vaccinations, like the hepatitis B vaccine, and medications to prevent serious eye infections. With declining rates of these vital interventions, doctors are noticing a concerning rise in refusals.

“I genuinely think these families care about their children,” said Dr. Kelly Wade, a neonatologist in Philadelphia. “However, conflicting information can make decision-making difficult for them.”

Social media plays a significant role in amplifying doubts about standard medical advice, with some misinformation targeting the safety and effectiveness of critical newborn measures like vitamin K and eye ointment. A federal advisory committee, now led by members aligned with anti-vaccine beliefs, recently voted to discontinue universal hepatitis B vaccinations for infants. Fortunately, a federal judge temporarily halted these decisions.

Dr. David Hill, a pediatrician in Seattle, noted that a shared belief among many anti-vaccine advocates is the misunderstanding that what is “natural” is always superior. “Nature has allowed significant infant mortality historically,” he pointed out, “which is why medical science has made strides to lower that risk.” Babies are born with low levels of vitamin K, which makes them vulnerable to bleeding until they begin consuming solid food around six months of age.

“Vitamin K is crucial for blood clotting,” highlighted Dr. Kristan Scott from the Children’s Hospital of Philadelphia. “It prevents severe bleeding, including into the brain.” Previously, a significant number of infants—up to 1 in 60—experienced vitamin K deficiency bleeding, a condition that remains rare today. However, infants who lack the vitamin K shot are 81 times more likely to experience serious bleeding issues compared to those who receive it.

Dr. Hill has witnessed the ramifications of declining the shot. “I cared for a toddler whose parents chose not to administer it,” he recounted, detailing how the child had a stroke-like incident as a newborn, which led to lasting developmental challenges.

During a recent Idaho chapter meeting of the American Academy of Pediatrics, Patterson reported on eight deaths related to vitamin K deficiency bleeding over the past thirteen months in the state, a statistic that underscores the gravity of the issue.

Other preventive measures also play critical roles in newborn health. Erythromycin eye ointment protects against gonorrhea, which can cause blindness if left untreated. Similarly, the hepatitis B vaccine averts liver failure and cancer risks. Dr. Susan Sirota, a pediatrician in Illinois, emphasized that even with testing, there’s always a possibility of a mother contracting infections after testing, which could endanger her newborn.

Parents offer various reasons for refusing these preventive steps, ranging from concerns about potential side effects to a desire for a more “natural” approach to childbirth. Dr. Steven Abelowitz, founder of Ocean Pediatrics, noted that misinformation and external influences, including opinions from friends or celebrities, contribute significantly to these decisions.

Abelowitz observed that mistrust is prevalent on both sides of the political spectrum. “It’s not limited to conservatives; there’s also a significant amount of skepticism on the liberal side,” he remarked.

Social media often spreads myths about these medical practices, including false claims about unregulated vitamin K alternatives that aren’t effectively absorbed by infants. Doctors are finding that reluctance to accept vitamin K shots often correlates with broader refusals of other critical measures. Sirota shared an example of a family that declined a glucose monitoring heel prick for a potentially at-risk newborn.

While care refusals aren’t brand new, Wade noted that they have become more common in the last two decades. Twelve years ago, Dana Morrison, a doula in Minnesota, chose not to give her son the vitamin K shot, opting instead for oral drops. “I wanted to maximize bonding time and avoid additional procedures,” she explained, although her perspective changed after her daughter faced complications during birth. Now, she regrets not administering the shot to her son.

Doctors are focused on changing these perspectives one family at a time. Respectful conversations can pave the way for understanding. Dr. Heather Felton, a pediatrician in Louisville, shared that she often addresses parents’ specific concerns about vitamin K, emphasizing its importance. Many families ultimately agree to administer it after discussions.

In Idaho, Patterson clears up common misconceptions, sometimes finding that parents are more willing to consider a vitamin K shot when they learn it’s not classified as a vaccine. Such discussions require time, especially when dealing with parents they don’t know well from their practices. But doctors are committed to investing that effort if it means protecting the lives of infants.

“I always conclude conversations with the reassurance that my passion for this topic stems from a genuine concern for children’s well-being,” Patterson said. “I recognize this is a contentious area, and I aim to show respect. Still, it deeply saddens me that we’re losing babies for reasons that could be prevented.”
