Robert F. Kennedy Jr. delivered remarks at a conference hosted by Children's Health Defense, the organization he founded that has been widely characterized as promoting anti-vaccine views, according to reports from multiple news outlets. Kennedy used the platform to question the safety of vaccines, consistent with positions he has long advocated.

Children's Health Defense has been a prominent voice in vaccine-skeptic circles, and Kennedy's appearance underscores his ongoing ties to the organization despite his broader political profile. The conference brought together individuals and groups who share skepticism about vaccine mandates and the mainstream scientific consensus on vaccine safety.

Kennedy's speech reiterated concerns about vaccine ingredients and regulatory oversight that he and the organization have raised for years. Public health experts and medical organizations have repeatedly rejected these claims, citing extensive clinical evidence supporting the safety and efficacy of approved vaccines.

The event drew renewed scrutiny given Kennedy's history as a public figure and his previous role in government discussions around public health policy. Critics argue that his platform amplifies misinformation that has contributed to declining vaccination rates in some communities, while supporters contend he is raising legitimate questions about pharmaceutical industry transparency and government oversight.
