U.S. vaccine policy faces scrutiny as FDA reverses decision on Moderna flu shot

The U.S. Food and Drug Administration reversed its earlier decision and agreed to review Moderna's new mRNA flu vaccine. The agency had previously refused to consider the application, a move some experts criticized.

Separately, the Centers for Disease Control and Prevention canceled a meeting of its vaccine advisory committee. Surgeon general nominee Casey Means was questioned about vaccines in a confirmation hearing, and a group of states sued the Trump administration over changes to childhood vaccine recommendations.
