The application approval could pave the way for the official approval of the other two vaccines, Moderna, which filed its application last month, and Johnson & Johnson.

Dr. Anthony Fauci, the top disease expert in the U.S., said in an interview earlier this month that the data for the vaccines "are about as good as it gets."
