Sharp Increase in Parental Refusal of Vitamin K Shots
Two newly published studies have found that an increasing number of parents are declining recommended vitamin K shots for their newborns, leading to a significant uptick in cases of dangerous bleeding. Since the 1960s, leading pediatric and health organizations have advised that all infants should receive vitamin K shots within 24 hours of birth to prevent a serious condition known as vitamin K deficiency bleeding.
Vitamin K Shots: Purpose and Recommendations
The American Academy of Pediatrics has issued standard pediatric recommendations calling for prompt vitamin K injections after birth. These shots support healthy blood clotting and help prevent life-threatening intracranial hemorrhaging and stroke. The Centers for Disease Control and Prevention and the World Health Organization also strongly recommend the procedure, emphasizing that infants do not get sufficient vitamin K from the placenta, breast milk, or formula, and do not start producing it themselves until they begin eating solid foods around six months of age.
New Data Highlights Bleeding Risks
One study, published in JAMA Pediatrics, analyzed electronic health records for over 11 million infants born in the United States between 2017 and 2025. The researchers found that the number of infants who did not receive a vitamin K shot doubled during this period, while instances of vitamin K deficiency bleeding rose by 347% to 107.4 cases per 100,000 infants.
A second study, published in JAMA, looked at data from more than 5 million infants and reported a rise in parental refusal of vitamin K shots from 3.1% in 2017 to 6.8% in 2025. These infants had a much higher risk of serious bleeding within their first six months of life compared to those who received the injection.
Possible Causes: Eroding Trust and Hesitancy
The studies suggest that increasing public distrust of health authorities, fueled by the aftermath of the COVID-19 pandemic and the rise in vaccine hesitancy, is contributing to more parents opting out of the vitamin K injection. Steven Woolf, a professor of family medicine and population health at Virginia Commonwealth University and a co-author of the JAMA Pediatrics study, stated, "We've gone generations without seeing this kind of increase in complications... It's very disheartening to see that progress in public health rolling back."
Researchers note that because vitamin K deficiency bleeding had become rare for decades, many families are unaware of its dangers and the necessity of preventative care.
Calls for Public Health Action
Following a ProPublica investigation published in May 2023 that highlighted cases where infants bled or died after not receiving the vitamin K shot, lawmakers called on the CDC to begin tracking both compliance with vitamin K recommendations and fatalities due to deficiency-related bleeding.
Summary of Pediatric and Health Authority Guidelines
Vitamin K injections given at birth are not vaccines but preventive measures advised by organizations like the American Academy of Pediatrics, CDC, and World Health Organization. Health experts stress that administering vitamin K shortly after birth is a simple step that can prevent life-threatening bleeding in infants.
