A federal judge weighing whether to block changes to U.S. vaccine guidance and an advisory panel did not immediately rule Feb. 13 after hearing from attorneys representing medical groups and the government.
Lawyers for the Society for Maternal-Fetal Medicine and other groups told U.S. District Judge Brian Murphy during a hearing at the federal courthouse in Boston that recent changes to the Centers for Disease Control and Prevention’s vaccine schedule and the CDC’s vaccine advisory panel violate federal law and will reduce vaccination rates.
