Data from Johns Hopkins University shows more than 40 million people in the United States have now had the coronavirus.

As cases rise, more people are focused on the rollout of booster shots.

Dr. Anthony Fauci is optimistic the shots will be available later this month.

He says they're aiming for the week of Sept. 20.

"It looks now, it is possible, and I think likely, that you will see Pfizer get rolled out first because of the data that they submitted to the FDA, " Dr. Fauci previously shared on New Day.

Moderna's booster may take a bit longer, while Johnson and Johnson's is still being researched.
