It's standard medical care: Newborn babies get a shot of Vitamin K. It helps their blood clot, and prevents potentially dangerous bleeds. But a few new parents decline the shots for their babies, and their numbers seem to be rising — an apparent trend that’s deeply troubling to doctors from Nashville to New Zealand.
American health authorities do not track Vitamin K refusals. But in recent years, anecdotal reports from hospitals and the CDC have described clusters of several babies who had brain bleeds and whose parents had declined the Vitamin K shot.
