Here's one tragic consequence of parents heeding the advice of anti-vaccine quacks and charlatans rather than medical experts: Vitamin K is a blood-clotting agent. But babies are naturally deficient in the vitamin. For over 65 years the vaccine has routinely been given to babies. Now some parents are rejecting the vaccine. The result? Babies are suffering internal bleeding and dieing. If they survive they may have brain damage which can cause paralysis or a long-term need for a feeding tube or ventilator. One tragic consequence of Americans rejecting medical experts and science.
