Fact Check: RFK is right about vaccines

Fact Check: "RFK is right about vaccines"

What We Know

Robert F. Kennedy Jr. (RFK Jr.) has been a prominent figure in the anti-vaccine movement for many years, particularly through his nonprofit organization, Children's Health Defense. His claims about vaccines have often been met with significant criticism from medical professionals and public health experts. For instance, he has been labeled as one of the leading spreaders of COVID-19 vaccine misinformation (Brookings). Despite this, in April 2025, as Secretary of the U.S. Department of Health and Human Services, he publicly endorsed the measles, mumps, and rubella (MMR) vaccine, stating, "The most effective way to prevent the spread of measles is the MMR vaccine" (NPR). This endorsement aligns with scientific consensus that supports the efficacy of the MMR vaccine (NPR).

However, RFK Jr.'s history includes numerous unfounded claims linking vaccines to various health issues, including autism. These claims have been thoroughly debunked by experts (AP News, FactCheck.org). His past statements have raised concerns about the potential for increased vaccine hesitancy, particularly in communities that have historically faced medical discrimination (Brookings).

Analysis

The endorsement of the MMR vaccine by RFK Jr. represents a significant shift from his previous anti-vaccine rhetoric. While his recent statement aligns with established scientific evidence on the effectiveness of the MMR vaccine, it is essential to consider the broader context of his history. His long-standing promotion of vaccine misinformation has contributed to public distrust in vaccines, especially among marginalized communities (Brookings, HuffPost).

Critics argue that RFK Jr.'s endorsement may not be genuine but rather a strategic move to maintain his political position while appeasing both his supporters and public health advocates (NPR). His previous claims have been widely discredited, and many experts remain skeptical about his ability to lead health policy effectively due to his history of promoting conspiracy theories and misinformation (BBC, FactCheck.org).

Moreover, the backlash from anti-vaccine activists following his endorsement indicates a fracture within the movement he once represented. Prominent anti-vaccine figures expressed disappointment, suggesting that RFK Jr. has deviated from their agenda (NPR). This reaction underscores the complexity of his position and the potential implications for public health messaging.

Conclusion

The claim that "RFK is right about vaccines" is Partially True. While RFK Jr.'s recent endorsement of the MMR vaccine aligns with scientific consensus, his extensive history of promoting vaccine misinformation complicates the validity of his statements. His past actions have contributed to vaccine hesitancy and distrust in the medical community, particularly among historically marginalized groups. Therefore, while his endorsement is a positive step, it must be viewed in the context of his broader track record.
