Former Trump WH COVID doc 'excited' for questions at RFK confirmation hearing

"That's why when he talks about transparency, I'm actually excited that in a Senate hearing he would bring forward his data and the questions that come from the senators would bring forth their data," Birx said of Kennedy. "What I know for sure is he's a very smart man who can bring his data and his evidence base forward." 

When Birx was asked about Kennedy's past controversial comments on vaccines, she said he has raised concerns about issues that "many Americans believe already is a problem."

"Every mom is seeing a classroom of kindergartners where one of the children has autism," she said. "That's scary to moms and dads. They want to know why. So it's not good enough for us to just say vaccines don't cause autism. It's us finding what is the cause of autism."

"That hearing would be a way for Americans to really see the data that you're talking about that we can't see that causation right now, but what is causing it?" Birx said, adding that addressing the cause of autism in children will be "critical."

"I think what has confused people is we weren't clear about what COVID vaccines do and don't," she said. "And so now people are questioning, well, what are my childhood vaccines do and don't. And they don't understand that some of the vaccines that their children are getting protect them from both disease and create herd immunity. And some of them that they get are just for their child, like H Flu and pneumovax to prevent their child from getting very serious illness."

"And we're just not explaining all of this correctly," she added of vaccines and what they do.

As for Kennedy's potential appointment, Birx said there's one important thing Kennedy can do to help him achieve success.

"I think the most important thing is what team he would bring with them, because you're talking about really a large cap corporation with a highly diverse group, which you have to really bring together and, frankly, eliminate some of the duplications between these agencies to really become more cost-effective."
