Dr. Deborah Birx, coronavirus coordinator at the White House came out last week saying the vaccines were overplayed and didn't work. What do you make of this?

Dr. Birx statement
I only included one article, but there are many. Why hasn’t anyone come forward to dispute this claim? What does Dr. Fauci think of this? Should there be an investigation or is this fake news either by the news or by Dr. Birx?
