Although mRNA vaccines saved millions of lives during the COVID-19 pandemic, U.S. Health Secretary Robert F. Kennedy Jr. incorrectly argued they are ineffective to justify the Department of Health and Human Service’s recent decision to cancel $500 million in government-funded research projects to develop new vaccines using the technology.

Health and Human Services Secretary Robert F. Kennedy Jr. revealed his agency will be cutting funding to mRNA development, calling the vaccine technology "ineffective" and claiming it poses more risks than benefits.

The US Department of Health and Human Services (HHS) plans to cancel $500m (£376m) in funding for mRNA vaccines being developed to counter viruses that cause diseases such as the flu and Covid-19.
