The US Department of Health and Human Services (HHS) canceled nearly $500 million in mRNA vaccine research contracts, citing excessive risk. This decision, driven by HHS Secretary Robert F. Kennedy Jr.'s skepticism towards mRNA technology, has also impacted unrelated projects. While Kennedy claims mRNA poses more risks than benefits for respiratory viruses, contradicting scientific evidence, the administration simultaneously supports mRNA research for cancer and genetic disorders. The cancellations stem from a broader reassessment of mRNA technology following the rapid development and deployment of COVID-19 vaccines.
