A U.S. government scientist who oversees the team responsible for collecting data on COVID-19 and RSV hospitalizations used to shape national vaccine policy has resigned, citing concerns over how such data would be used by the Trump administration.

Fiona Havers, who oversaw CDC respiratory virus data, told colleagues she no longer had confidence the data would be used objectively to set vaccine policy.

The U.S. Centers for Disease Control and Prevention panel of vaccine experts will vote on shots for respiratory syncytial virus and influenza at a meeting scheduled for June 25 and 26, according to the agency's website.
