Autopsy records reviewed in multiple states describe vitamin K deficiency bleeding as a cause or contributor to infant deaths, often noting that babies did not receive a preventive vitamin K shot at birth. The documents also chronicle what babies arrived with,
An infant’s life can change in hours—before most parents even get a chance to worry about anything beyond feeding and sleep.. Autopsy records reviewed across several states depict the aftermath of a different kind of emergency: late. catastrophic bleeding tied to vitamin K deficiency in newborns. a condition medical professionals say is largely preventable with a simple shot shortly after birth.
The records show vitamin K deficiency bleeding listed as an immediate cause of death or as a contributing factor. and in many cases they also reference that vitamin K was not received as part of preventive care after the baby was born.. One example comes from a Minnesota case in which the medical examiner determined the baby died of vitamin K deficiency bleeding and included the detail that vitamin K was not administered as preventive care after birth.
The medical stakes are tied to what vitamin K does in the body and how little of it newborns naturally have at the time of delivery.. Two researchers were awarded the Nobel Prize in 1943 for discovering vitamin K and its ability to form clots and stop bleeding in babies.. In the U.S.. the vitamin K shot has been a standard intervention for newborns for decades. after the American Academy of Pediatrics recommended it more than 60 years ago.
In more recent years, however, parents have increasingly refused the shot.. While the vitamin K shot is not a vaccine. it has become entangled in the anti-vaccine movement. and false and misleading information online has led some parents to believe the shot is harmful.. Other parents have described a desire for a more natural birthing experience without pharmaceutical intervention. while some have also said they simply did not want their babies to go through the pain of an injection they believed unnecessary.
The shift is documented through hospital data and research studies.. A national study of more than 5 million births found that the rate of babies not receiving vitamin K jumped 77% from 2017 to 2024.. The Centers for Disease Control and Prevention reports that newborns who do not get the shot are 81 times more likely than those who do to develop late vitamin K deficiency bleeding.. In many cases. there are no warning signs—babies can appear healthy and happy in the days and sometimes hours before suffering catastrophic bleeding.
One central tension in the record is what is tracked—and what is not.. State and federal agencies do not track which babies do not receive the shot and which babies suffer bleeds or die.. Experts interviewed in the reporting said the number of deaths directly attributed to vitamin K—fewer than a dozen annually—is only part of the story.. They described hundreds of babies dying each year from spontaneous bleeding in the brain. and said some of those deaths are likely related to vitamin K deficiency bleeding.. Doctors have therefore called for better reporting and tracking.
What the autopsies add is detail that turns statistics into something families can recognize: a newborn’s identity. the circumstances on arrival. and the physical findings that follow.. Many reports reviewed included summaries beyond the medical findings. listing items the infants arrived with. including a hospital band around the ankle. an unsoiled diaper. and a blue blanket.. The records also frequently included particulars such as a baby’s weight, length, hair and eye color.
In one described case, the account of injury is graphic in its medical specificity.. For a 1-month-old from Alabama. the autopsy found subdural and subarachnoid hemorrhage—bleeding in different areas immediately on top of the brain.. Subdural bleeding occurs when blood collects under one of the layers of tissue inside the skull that protect the brain. while subarachnoid bleeding occurs in the space below a different layer.. The report also described cerebral edema. a swelling in the brain. and necrosis of the brain. meaning death of living brain tissue.. The cause was listed as “hemorrhagic disease of newborn. ” the previous name of vitamin K deficiency bleeding that some clinicians still use.
Autopsy records also show how doctors responded once those bleeds were discovered.. Some reports had a section titled “Evidence of Medical Intervention. ” describing steps doctors and nurses took to try to save the babies. including inserting tubes into the babies’ airways. connecting them to IVs. and ordering blood transfusions.. Those sections can be especially difficult to read because they lay out exactly what was attempted—suggesting how differently the outcome might have gone if prevention had occurred.
In a case from Kentucky, the medical team attempted several lifesaving measures, but the baby coded twice. Doctors were able to resuscitate him the first time; after about half an hour of trying to bring him back again the second time, the parents told the team they could stop.
The documents repeatedly emphasize how preventable these deaths could have been, down to the scale of what remains.. Images of tiny footprints appear in autopsy records and function as a grim inversion of a ritual families often do at home: parents commonly frame a baby’s footprints to hang on a wall or tuck them into keepsake boxes. with the prints often triggering a rush of happy memories.. When those footprints appear in autopsy records. they become a tragic reminder of how tiny the babies were when they died.
The pattern is consistent across the cases described: autopsies list vitamin K deficiency bleeding as a cause or contributor. notes about missing preventive vitamin K shot appear alongside medical findings. and the records then document both the details of what doctors found and the intensity of the efforts to save lives after catastrophic bleeding had already begun.
For privacy. ProPublica is not sharing the babies’ names. the dates or years of death. or the locations within a state.. The reporting also notes that not every death is investigated by a medical examiner or coroner. but open records requests were filed in several states and counties to obtain the autopsies that were available.
In the end. the accounts in these records converge on a single point: vitamin K deficiency bleeding. including its earlier name “hemorrhagic disease of newborn. ” is documented in official medical determinations. often alongside the explicit fact that vitamin K was not given as preventive care after birth.
