Health and Human Services Secretary Robert F. Kennedy Jr. announced Tuesday a crackdown on mRNA vaccine technology and research to develop it, following months of pressure from anti-vaccine activists.
According to HHS, the Trump administration has launched “a coordinated wind-down” of 22 mRNA projects supported by the Biomedical Advanced Research and Development Authority, the government’s biodefense agency.Other mRNA projects funded by HHS are not affected by the new announcement.
The contracts will either be canceled or altered, according to HHS, including projects focused on creating an H5N1 bird fluvaccine and developing respiratory virus therapeutics.
In total, the administration said the changes will affect nearly $500 million in mRNA-related projects, but details of all such contracts were not immediately made available. HHS said some late-stage mRNA initiatives will continue to preserve “taxpayer investment.”
Once celebrated as a major scientific advancement that allowed for the rapid development of coronavirus vaccines, mRNA technology has since come under scrutiny by conservatives and the Trump administration
“We reviewed the science, listened to the experts, and acted,” Kennedy said in a statement. “We’re shifting that funding toward safer, broader vaccine platforms that remain effective even as viruses mutate.”
Traditional vaccines deliver viral proteins or weakened versions of a virus to teach the immune system how to fight it. In contrast, mRNA vaccines work by delivering instructions to the body’s cells on how to manufacture viral proteins. They are faster to develop than traditional vaccines, which public health experts say make them a valuable tool in fighting emerging pathogens or the next pandemic.
The Trump administration has denigrated mRNA vaccines as a dangerous technology, but large-scale studies have established that they are safe and effective.
