Johnson & Johnson released the efficacy results of their one-shot Covid-19 vaccine candidate as coronavirus variants are increasingly being found in the U.S. The company announced their vaccine was shown to be 66% effective in preventing moderate and severe disease in a global Phase 3 trial and 85% effective against severe disease. It also was shown to be 72% effective against moderate and severe diseases in the U.S. While the trial apparently shows a lower efficacy rate than the other two vaccines on the market from Pfizer and Moderna, experts say the Johnson & Johnson vaccine would help fight the pandemic. Dr. Leana Wen is the former Baltimore Health Commissioner, an emergency room physician and a CNN Medical Analyst. She tells Anderson Cooper these results are promising. Plus, Pres. Joe Biden plans to intensify public lobbying for his Covid-19 relief bill and says it “has to pass.” Independent Senator Bernie Sanders has said the timeline for this bill to pass is “as soon as we possibly can.” He joins AC360 to give an update on where the $1.9 trillion bill stands on Capitol Hill and whether or not the Democrats have the votes to pass without any Republican support.   Airdate: January 29, 2021   Guests: Dr. Leana Wen Sen.
