Dr. Moncef Slaoui is the chief scientific adviser for Operation Warp Speed, and arguably the most powerful force in the mission to vaccinate America from the coronavirus. The scientist, a 30-year pharmaceutical industry veteran and registered Democrat, says he doesn’t “want to get into the politics” even though everything about the United States’ coronavirus response — from mask-wearing to President Trump’s illness — seems to have been politicized.

Dr. Slaoui says he’s an adviser with “significant influence” — not a decision maker. And while he makes no guarantee about vaccine timelines, he does stand by a commitment to quit if politics interferes with science, saying, “I can guarantee that I will say what I think, and I am saying what I think.”
