A day after Centers for Disease Control and Prevention Director Rochelle Walensky broke with her agency’s advisory committee to recommend booster shots for adults with high-risk jobs, she pushed back against the notion that she had overruled her experts.

Walensky on Thursday recommended that people whose jobs put them at heightened risk of illness seek a third vaccine dose if they initially got the Pfizer-BioNTech vaccine. On Friday, she said that the advisory panel had deliberated on the issue for hours and that the decision was a “scientific close call.”

“In that situation, it was my call to make,” Walensky said at a briefing of the White House coronavirus task force. “If I had been in the room, I would have voted yes.”
