James P. Crowley: Newborn Vitamin K Refusal a 347% Surge in Life-Threatening Bleeding

James P. Crowley, Professor of Medicine emeritus at Brown University, shared a post on LinkedIn:

“A growing number of infants in the United States are experiencing potentially life-threatening bleeding as more parents decline a vitamin K shot that has long been recommended for newborns, according to two new studies.

One of the studies found a 347 percent increase in these bleeding cases since 2017.

For decades, the American Academy of Pediatrics has recommended that every newborn receive an injection of vitamin K, which helps blood clot and can protect against sudden and catastrophic bleeding that can occur even in otherwise healthy babies.

The injection is not a vaccine, but as mistrust in medicine has grown and as Health Secretary Robert F. Kennedy Jr. and other prominent health figures have cast doubt on the importance of childhood vaccinations, more parents have started forgoing it.”
