She also talks with vaccine researcher, advocate and Co-Director of the Center for Vaccine Development at Texas Children’s Hospital and Dean of the National School of Tropical Medicine at Baylor College of Medicine, Dr. Peter Hotez, about how we can fight the powerful tide of disinformation, overcome distrust, and help get more people the facts they need to make the right health decisions for themselves and their families.
