U.S. Centers for Disease Control and Prevention (CDC) Director Dr. Rochelle Walensky denied overruling an agency advisory committee that had reportedly refused to endorse Pfizer-BioNTech booster shots during a White House briefing Friday afternoon.
"I want to be very clear that I did not overrule an advisory committee," Walensky said while speaking in a briefing alongside President Joe Biden's chief medical adviser, Dr. Anthony Fauci, U.S. Surgeon General Dr. Vivek Murthy and White House COVID-19 Response Coordinator Jeff Zients.
Walensky noted that she had listened intently to both the U.S. Food and Drug Administration (FDA) advisory committee as well as to the "exceptional group of scientists" who had deliberated for an hour over very difficult questions and "where the science was."
"I listened to the comments on the votes and this was a scientific close call," she said. "And, I think you could tell by the duration of the meeting and the discussions that this was a scientific close call."
In that situation, Walensky said, it was her call to make.
"If I had been in the room, I would have voted ‘yes,’ and that was ... how my recommendations came out after listening to all of their scientific deliberations. To the extent that people are concerned about confidence, I would say they should listen to the deliberations themselves. We did it publicly, we did it transparently and we did it with some of the best scientists in the country," she added.
On Thursday, the CDC endorsed booster shots for millions of older or otherwise vulnerable Americans, including President Biden, who joked Friday that it was "hard to acknowledge" he was over 65 years old.
"All kidding aside, I’ll be getting my booster shot as soon as I can get it done," Biden told reporters from the White House.

Those eligible for the Pfizer-BioNTech boosters starting on Friday include people 65 years or older, adults 18 or older with underlying health conditions and those who are at increased risk of exposure, including people in prisons, grocery store workers, health care workers and teachers.
With health care systems once again at maximum capacity, Walensky said it was her job to recognize where actions can have the greatest impact and that the booster recommendations were made with the "intention to do the greatest good, even in an uncertain environment."

She said that she must do what she can to preserve the health of the country, and Murthy assured that the health of recipients of Moderna and Johnson & Johnson vaccines matters "just as much as other vaccine recipients" with the goal of making booster recommendations for them a high priority in coming weeks.
