The entire U.S. population could be vaccinated against Covid-19 by June, and there could be enough doses to immunize the rest of the nearly 8 billion people in the world by early to mid-2022, the Trump administration’s vaccine chief said Tuesday.
“Hopefully by the middle of the year, I hope most Americans will have been immunized, which means the level of hesitancy that exists currently will have been decreased because people will have learned more information … about the vaccine,” Moncef Slaoui, chief science advisor for the White House’s Operation Warp Speed, told The Washington Post in a livestream interview.
