NIH Director Dr. Jay Bhattacharya says "I trust the science" on childhood vaccines

Dr. Jay Bhattacharya, the director of the National Institutes of Health, told "Face the Nation with Margaret Brennan" that "I trust the science on vaccines," despite previous comments from Health and Human Services Director Robert F. Kennedy Jr. about childhood vaccines. Amid the growing measles outbreak, Kennedy has now said parents should vaccinate their children against the disease.
