She said recent actions by the Department of Health and Human Services have created "pure confusion" for parents, heightening distrust of the medical community. A spokesman for HHS said it "rejects" the premise that vaccine policy has had any impact on the use of newborn treatments such as vitamin K and erythromycin eye ointment. "Babies aren't born with enough vitamin K, which helps with blood clotting... it is used up ⁠in pregnancy and ‌it doesn't cross the placenta very well," Clouser said. Pediatricians emphasized that parents should ask questions and understand the health benefits of vaccines ⁠and other preventive care. "We encourage all parents to come in and talk," ‌said Dr. Michael Glazier, a pediatrician in Jacksonville, Florida.
