Kennedy Jr. became the country's top health official, the Centers for Disease Control and Prevention has already pulled back some of its efforts to protect Americans with safe, life-saving vaccines.

The postponed ACIP meeting comes barely a week after Robert F. Kennedy, Jr. was confirmed as Secretary of Health and Human Services, despite controversy regarding his anti-vaccine history.

Food and drug companies have expressed optimism, but the new health secretary and his MAHA movement will likely make waves.
