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 17 members of the CDC's vaccine advisory committee, who were ousted last week, argued their abrupt dismissal has "left the U.S. vaccine program critically weakened."
