The shot that once made brain bleeding in newborns almost vanish is increasingly being refused by parents. ProPublica reports that more than 5% of US babies didn't receive the routine vitamin K injection in 2024, a 77% jump since 2017, as some parents—often influenced by social media misinformation and broader mistrust of medicine—decline the decades-old standard of care. The consequences can be catastrophic: Doctors describe infants who seemed fine, then suddenly seized, stopped breathing, or suffered massive brain hemorrhages tied to vitamin K deficiency bleeding, a condition that research shows is 81 times more likely without the shot and fatal in about 1 in 5 cases, per the CDC. "Many more babies survive the bleeding but suffer massive brain bleeds and lasting injuries," the outlet notes.
ProPublica explains that newborns are born with very little vitamin K in their systems, which helps blood to clot. Breast milk contains very little of the vitamin, putting breastfed babies even more at risk. Despite near-universal endorsement from pediatric groups and the WHO, refusal of the shot is rising in certain hospital systems, with some reporting rates nearing 10% or higher. Yet no state or federal agency systematically tracks vitamin K shot refusals or related injuries and deaths, leaving experts to warn that the true toll is obscured on death certificates, labeled only as "brain bleeding." "A lot of the providers don't have this on their radar," a Yale Medicine pediatric hospitalist says. "The lack of data is almost acting like a reassurance for families that this risk is worth taking." More here.
