The U.S. Division of Well being and Human Companies will cancel contracts and pull funding for some vaccines which might be being developed to combat respiratory viruses like COVID-19 and the flu.
Robert F. Kennedy Jr. introduced in an announcement Tuesday that 22 tasks, totalling $500 million US, to develop vaccines utilizing mRNA know-how can be halted.
Kennedy’s determination to terminate the tasks is the most recent in a string which have seen the longtime vaccine critic’s agenda overriding scientific standards on the nation’s well being division. Kennedy has pulled again suggestions across the COVID-19 photographs, fired the panel that makes vaccine suggestions, and refused to supply a vigorous endorsement of vaccinations as a measles outbreak worsened.
The well being secretary criticized mRNA vaccines in a video on his social media accounts, explaining the choice to cancel tasks being led by the nation’s main pharmaceutical corporations, together with Pfizer and Moderna, that provide safety towards viruses just like the flu, COVID-19 and H5N1.
“To switch the troubled mRNA applications, we’re prioritizing the event of safer, broader vaccine methods, like whole-virus vaccines and novel platforms that do not collapse when viruses mutate,” Kennedy stated within the video.
Infectious illness consultants say the mRNA know-how utilized in vaccines is secure, they usually credit score its growth in the course of the first Trump administration with slowing the 2020 coronavirus pandemic. Future pandemics, they warned, can be more durable to cease with out the assistance of mRNA.
‘Harmful determination’
“I do not suppose I’ve seen a extra harmful determination in public well being in my 50 years within the enterprise,” stated Mike Osterholm, a College of Minnesota professional on infectious ailments and pandemic preparations.
He famous the know-how affords potential benefits of speedy manufacturing, essential within the occasion of a brand new pandemic that requires a brand new vaccine.

The shelving of the mRNA tasks is short-sighted as issues a couple of chook flu pandemic proceed to loom, stated Dr. Paul Offit, a vaccine professional at Youngsters’s Hospital of Philadelphia.
“It is actually saved thousands and thousands of lives,” Offit stated of the prevailing mRNA vaccines.
Scientists are utilizing mRNA for greater than infectious illness vaccines, with researchers all over the world exploring its use for most cancers immunotherapies. On the White Home earlier this yr, billionaire tech entrepreneur Larry Ellison praised mRNA for its potential to deal with most cancers.
Historically, vaccines have required rising items of viruses, usually in rooster eggs or big vats of cells, then purifying that materials. The mRNA method begins with a snippet of genetic code that carries directions for making proteins. Scientists decide the protein to focus on, inject that blueprint and the physique makes simply sufficient to set off immune safety — producing its personal vaccine dose.
In an announcement Tuesday, HHS stated “different makes use of of mRNA know-how inside the division are usually not impacted by this announcement.”
The deserted mRNA tasks sign a “shift in vaccine growth priorities,” the well being division stated in its assertion, including that it’ll begin “investing in higher options.” No particulars had been supplied on what these different applied sciences may be.
