Vitamin K Shot
What is it?
Unlike other shots, the vitamin K shot is not used to prevent an infectious disease. Instead, it is more like taking a vitamin supplement. Vitamin K is naturally present in a wide variety of foods, especially leafy green vegetables, and it is important for clotting and preventing excessive bleeding. The vitamin K injection is recommended because babies naturally have very low levels of vitamin K, which puts them at risk of life-threatening bleeding called vitamin K deficiency bleeding (VKDB).
According to the CDC, infants who receive the vitamin K shot are 81 times less likely to develop severe bleeding. 4 million babies are born in the United States each year. If we stopped giving the vitamin K shot at birth, more than 200 infants would develop VKDB every day.
