Life-threatening bleeding in American infants has roughly doubled in a year, and the medical establishment is pointing the finger straight at parents who are refusing a routine vitamin K shot at birth — trust that public health authorities themselves torched.

Two studies published in JAMA and JAMA Pediatrics confirm what the numbers have been signaling: as more parents skip the vitamin K injection — a single dose that has been standard care since 1961 — bleeding episodes in infants are climbing fast. Dr. Steven Woolf, an epidemiologist at Virginia Commonwealth University, put it plainly: "The rate in 2025 was approximately double what it was in 2024."

The stakes are real. Babies are born with almost no vitamin K, which is essential for blood clotting, and they don't get meaningful amounts from food until they start eating solids around six months. Without the shot, infants are 81 times more likely to develop vitamin K deficiency bleeding, or VKDB, which can cause spontaneous internal bleeding — including in the brain.

Dr. Kristan Scott and colleagues at Children's Hospital of Philadelphia analyzed records for more than 5.2 million U.S. infants born between 2017 and 2025. They found that roughly 4.5% — 234,825 babies — had no documented vitamin K shot. Infants who skipped the shot had a 47% higher risk of bleeding after adjusting for gestational age, sex, maternal characteristics, and insurance status. Intracranial bleeding was more than twice as common: 33 cases per 10,000 births among those without the shot, compared with 13 among those who received it. Death during birth hospitalization among babies with a bleeding diagnosis was also more common in infants without documented vitamin K, according to senior co-author Dr. Kevin Dysart.

A separate study by Woolf's team, covering 11 million infants, found the percentage of newborns receiving vitamin K fell from 97.7% to 95% between 2017 and 2025, while VKDB rates nearly quadrupled over the same span.

So the data is clear. What's less clear — and what the press corps doesn't want to grapple with — is why parents are refusing.

NBC News framed the trend as accelerating under Health Secretary Robert F. Kennedy Jr., noting he "spent decades sowing mistrust about vaccines" and has since dropped childhood recommendations for six vaccines. The New York Post, by contrast, acknowledged the trend more neutrally, noting it "comes amid growing distrust of public health recommendations, a trend that has picked up steam since the COVID-19 pandemic." NBC buried the more uncomfortable context; the Post barely touched it.

Here's what neither outlet wants to say: parents didn't invent this distrust from thin air. The public health establishment spent years locking down churches while letting big-box stores stay open, forcing masks onto toddlers, pushing puberty blockers and cross-sex hormones on minors, and labeling anyone who asked questions a threat to their neighbor. The CDC doesn't even track vitamin K refusal or bleeding rates, and an HHS spokesperson declined to say whether the agency would start. You don't get to systematically demolish your own credibility and then act shocked when parents flinch at a needle in the delivery room.

Scott acknowledged as much, saying the findings "highlight the need to better understand why its use is declining." That understanding starts with a mirror.
