At the morgue, the babies were brought in with their diapers and blankets and with their hospital ID bracelets still wrapped around their tiny ankles. The pathologists’ findings were like those you would typically see in ailing adults, not newborns — the kind of bleeding seen during strokes or brain tissue loss similar to what happens when radiation is administered to treat cancer.
Their autopsies, which took place over the last several years, all came to the same conclusion: The deaths were caused, in whole or in part, by a rare but potentially fatal condition known as vitamin K deficiency bleeding.

Two weeks ago, at a House subcommittee hearing, Rep. Kim Schrier, D-Wash., pressed Health and Human Services Secretary Robert F. Kennedy Jr. to reassure parents that the vitamin K shot is safe. He refused and pushed back.
“I’ve never said, literally never said, anything about it,” Kennedy said.
“That’s exactly the point,” responded Schrier, who is a doctor. “You don’t say anything about it, but the doubt you’ve created about all of medicine and science is causing parents to make dangerous decisions.”
