Biden Sets New Vaccine Goal: Beijing Codes Offices: Virus Update Bloomberg 1 hr ago Bloomberg News (Bloomberg) -- Beijing is color-coding office buildings to encourage more workers to get vaccinated. China, the origin of Covid-19, will drive the post-pandemic recovery, contributing more than one-fifth of all economic expansion over the next five years, based on International Monetary Fund predictions. U.S. President Joe Biden said he wants all American adults to be eligible for a coronavirus vaccine by April 19, two weeks earlier than his previous goal. Brazil surpassed 4,000 Covid-19 deaths in one day for the first time. A study of 33 adults showed antibodies to the virus persist for at least six months after receiving the second dose of Moderna Inc.’s vaccine. The U.K. will add the shot to its vaccine roll-out starting Wednesday.
