✅ No, we couldn't find enough information supporting the claims made by Robert F. Kennedy Jr. regarding mRNA vaccine development cuts on major authoritative news outlets, and his justifications have been widely challenged by experts.

Here are some relevant sources:

This article fact-checks Kennedy Jr.'s claim that mRNA vaccines fail to protect effectively and are unsafe. It states these claims are contradicted by peer-reviewed scientific literature and expert consensus, emphasizing the vaccines' proven effectiveness and safety during the COVID-19 pandemic.

2. https://www.statnews.com/2025/08/13/rfk-jr-mrna-vaccine-research-science-papers-justification-misreading/ - (Trust Score 8/10)

This report explains that Kennedy's case against mRNA vaccines collapses under scrutiny of the scientific evidence, pointing out that his interpretation of data is flawed and that federal funding cuts to these projects are controversial among public health experts.

3. https://www.hhs.gov/press-room/hhs-winds-down-mrna-development-under-barda.html - (Trust Score 9/10)

Official HHS press release confirming the winding down of some mRNA vaccine projects under BARDA, but it does not support Kennedy’s claims about vaccine ineffectiveness or safety concerns and frames it as a strategic shift in funding priorities.

These sources from credible public health, medical news, and government outlets indicate that the rationale given by RFK Jr. for the halt in mRNA vaccine development projects is not aligned with the broader scientific consensus and is widely disputed.
