This week, President Donald Trump called Operation Warp Speed, a public-private federal program that helped speed up the development and distribution of mRNA Covid-19 vaccines in record time “one of the most incredible things ever done in this country.

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.

In justifying the government's termination of $500 million in funding for mRNA vaccine projects, Health and Human Services Secretary Robert F. Kennedy Jr. falsely claimed mRNA vaccines "fail to protect effectively" against COVID-19 and suggested they are unsafe.
