RFK Jr. pulls $500M meant for vaccine development

Summary

mRNA project cancellations

The Department of Health and Human Services announced it would stop nearly two dozen projects totaling $500 million that utilized mRNA technology.

Kennedy's stated rationale

Robert F. Kennedy Jr. stated in a post on X that data shows the vaccines "fail to protect effectively against upper respiratory infections, such as COVID-19 and the flu."

Expert backlash

Medical professionals voiced concerns regarding the cancellations. Mike Osterholm of the University of Minnesota told the Associated Press that he hasn't "seen a more dangerous decision in public health in the last 50 years."


The Department of Health and Human Services (HHS) announced Tuesday that it would halt nearly two dozen projects worth $500 million, all using mRNA technology. The decision comes from HHS Secretary Robert F. Kennedy Jr., a familiar vaccine critic.

In a post on X, Kennedy stated that the Biomedical Advanced Research and Development Authority (BARDA) has been researching and canceling investments in mRNA vaccine development. He said data shows the vaccines fail to protect effectively against upper respiratory infections, such as COVID-19 and the flu.

Proposals canceled

Projects canceled include proposals from Pfizer, Sanofi Pasteur and other drugmakers. A statement from HHS said some contracts will be wrapped up, as they were in the final stages and already had prior taxpayer investment. However, no new mRNA-based projects will be initiated.

What’s next

Kennedy said the administration will transition to a different approach — a “universal” vaccine that mimics natural immunity. 

“And it could be effective. We believe it’s gonna be effective against not only coronaviruses, but also the flu. And it’s going to be a much safer and much more effective vaccine,” Kennedy said.

Medical professionals respond

The announcement received a swift response, with medical professionals voicing their opinions and concerns.

Mike Osterholm from the University of Minnesota told The Associated Press that he hasn’t seen a more dangerous decision in public health in the last 50 years. 

A virologist and vaccine expert at Children’s Hospital of Philadelphia also commented on the move. He said Kennedy “has once again made a decision, not based on scientific evidence, that puts this country at unnecessary risk.”

In the HHS statement, Kennedy said, “Let me be absolutely clear: HHS supports safe, effective vaccines for every American who wants them. That’s why we’re moving beyond the limitations of mRNA and investing in better solutions.”

The move is the latest from RFK Jr., who, since joining the administration, has removed COVID shot recommendations for healthy children and pregnant women. He also dismissed the panel that establishes vaccine guidelines.

Why this story matters

HHS has halted nearly two dozen mRNA vaccine projects, shifting funding toward a different vaccine approach and sparking strong responses from the medical and scientific communities about the future direction of public health policy.

Vaccine policy shift

HHS is ending new mRNA vaccine projects in favor of developing a "universal" vaccine, marking a significant policy change that could alter the nation’s approach to combating respiratory viruses.

Scientific and medical response

Many medical experts and scientists have sharply criticized the decision, raising concerns about its potential impact on public health and the importance of evidence-based policymaking.

Public health implications

Changing course on vaccine strategy could affect preparedness against diseases like COVID-19 and flu, influencing the health outcomes for millions and shaping future infectious disease responses.

Community reaction

Many public health and medical experts express concern, warning that ending mRNA funding could hinder rapid responses to future pandemics, while some vaccine-skeptic groups or individuals welcome the move as addressing safety concerns.

Context corner

mRNA vaccine technology gained prominence in the COVID-19 pandemic due to its rapid development and adaptability but remains controversial among some policymakers and public figures over perceived risks and effectiveness for respiratory viruses.

Debunking

Numerous peer-reviewed studies and infectious disease experts cited in the articles contest Kennedy's claim that mRNA vaccines are broadly ineffective, pointing out robust evidence that these vaccines reduce severe illness and mortality from COVID-19.

Bias comparison

  • Media outlets on the left frame the termination of nearly $500 million in mRNA vaccine funding as a “reckless” and “unforgivable” blow to vital public health advances, emphasizing RFK Jr.'s anti-vaccine history and expert condemnation to highlight scientific risks and the endangerment of pandemic preparedness.
  • Not enough unique coverage from media outlets in the center to provide a bias comparison.
  • Media outlets on the right adopt a more cautious, pragmatic tone, portraying the decision as a “science-based” pivot toward “safer, broader vaccine platforms” due to mRNA vaccines’ alleged failure to protect effectively against respiratory viruses.
