A health‑analytics review of more than one million U.S. births shows that newborns who did not receive the standard vitamin K injection within the first day rose sharply in the first half of 2026. The non‑administration rate increased by more than 57% from January to June, reaching 8.1% of infants by the end of June, up from 5.2% six months earlier. The analysis, conducted by Truveta, indicates the current refusal rate is 2.5 times the average recorded between 2019 and 2024.
Vitamin K is essential for blood clotting, and infants are born with low levels of the vitamin. The Centers for Disease Control and Prevention notes that without the injection, babies are about 81 times more likely to experience life‑threatening bleeding in the brain or gut during the first six months, and one in five of those severe cases can be fatal. The CDC continues to recommend the shot for all newborns.
Pediatricians and neonatologists attribute the surge in refusals to growing mistrust of vaccines and routine newborn care, a trend they say has been amplified by recent public statements and policy proposals from figures such as Robert F. Kennedy Jr. and former President Donald Trump. The data also reveal a gender gap: in June 2026, 8.9% of female infants and 7.3% of male infants missed the injection, a disparity echoed in earlier hospital‑based studies.
Clinicians are adapting by requiring parents who decline the shot to sign acknowledgement forms, expanding access to the injection in outpatient settings, and monitoring at‑risk infants more closely. Several doctors, including Dr. Nia Heard‑Garris and Dr. Sarah Coggins, warn that the trend threatens infant health and are initiating studies to better understand the underlying causes.
