The U.S. public health system is headed to a “very dangerous place” with Health Secretary Robert F. Kennedy Jr. and his team of anti-vaccine advisers in charge, fired Centers for Disease Control and Prevention chief Susan Monarez warned senators on Wednesday.

Describing extraordinary turmoil inside the nation’s health agencies, Monarez and former CDC Chief Medical Officer Chief Debra Houry said Kennedy, a longtime vaccine skeptic, and his political advisers repeatedly rebuffed data supporting the safety and efficacy of vaccines.
