Not a vaccine but relevant here on this thread because of the fear-mongering caused by the anti-vaccine brigade, there are now reports of newborn and up to six-months old babies dying in the US of bleeding because their parents have refused the at-birth Vitamin K injection.
Babies have a very low level of Vt. K which means they have an inability of blood to clot.
This injection prevents this and is given at the same time as the Hep vaccine.
