"All newborns lack vitamin K. No matter how much vitamin K a mother consumes, it doesn’t sufficiently pass through the placenta, and breast milk contains only small amounts. That puts babies who are exclusively breastfed at a higher risk for vitamin K deficiency bleeding. Formula is fortified with vitamin K, but even with that, experts agree, babies should still get the shot." Also, "Babies who don’t get the vitamin K shot, research shows, are 81 times more likely than those who do to develop late vitamin K deficiency bleeding, where in many cases oxygen can’t reach their brains and blood pools around their skulls. Perhaps most alarming is that, according to the CDC, 1 in every 5 babies with vitamin K deficiency bleeding will die." But tracking systems are lacking and misinformation is readily available
A lifesaving injection given at birth to prevent severe bleeding has become collateral damage of the anti-vaccine movement.
