This week, the White House announced that it’s setting up a $5 billion program, called Project Next Gen, to support next-generation COVID-19 vaccines and treatments. Project Next Gen is a big step toward actually ending the pandemic, not just pretending it’s over. The federal government can support large-scale clinical trials and speed up regulatory approval in a way that no research group or company could. Still, the U.S.’s prior vaccine campaigns don’t inspire confidence that this project will lead to widespread adoption of new shots when they become available.
