Kbc, Don addressed the p3 in the May PBA presentation, he claimed the FDA requested a p3 covid program for the US instead of the alleged p2 to be run in Canada and Brazil (the one where read out “should be around August”)

After listening to the video, the Phase 2 & 3 are different than I thought.  He refers to the Phase 3 as a "second follow-on trial" in the US as you describe. I had been thinking they would be sequential, but the graphic says that the Phase 3 will "launch in parallel".
