Fact check: Robert Kennedy won a higher court case against the MRNA vaccines?

Checked on May 15, 2025

1. Summary of the results

The claim about Robert Kennedy winning a Supreme Court case against mRNA vaccines is definitively false. Multiple independent sources confirm that:

  • No such Supreme Court ruling exists [1] [1]
  • RFK Jr. himself has explicitly rejected similar claims, stating in 2021 that "somebody made it up" [2]
  • A search of the Supreme Court's opinion archive shows no such ruling [3]

2. Missing context/alternative viewpoints

Several important contextual points are missing from the original statement:

  • While Kennedy has been involved in over 30 vaccine-related lawsuits, none have reached the Supreme Court level [1]
  • The Supreme Court has actually rejected two vaccine-related cases brought by Children's Health Defense, Kennedy's organization [1]
  • Kennedy recently lost a different lawsuit against Meta/Facebook, where the court affirmed Meta's First Amendment right to moderate vaccine-related content [4]
  • The Supreme Court's role is to rule on legal applications, not scientific facts, as confirmed by law professor Margaret Foster Riley [1]

3. Potential misinformation/bias in the original statement

The spread of this misinformation appears to be part of a larger pattern:

  • Kennedy has faced criticism from senators and medical experts during his Health and Human Services Secretary confirmation hearing for his vaccine skepticism [5]
  • The Associated Press has explicitly labeled claims about Supreme Court victories regarding vaccines as "False" [3]
  • The original claim incorrectly implies that mRNA vaccines are gene therapies, which has been debunked [2]

This type of misinformation benefits:

  • Anti-vaccine advocacy groups seeking legitimacy through false claims of legal victories
  • Political figures who use vaccine skepticism as a platform
  • Social media accounts and websites that gain engagement through spreading sensational but false claims about vaccine-related court cases
