A COVID-19 vaccine may come soon

摘要

In January, researchers lined up on the starting blocks, waiting to hear a pistol. The shot came on January 10, when sci-entists in China announced the genetic makeup of SARS-CoV-2, the coronavirus that causes COVID-19. With that infor-mation, the race toward a vaccine began. Over six months later, with about 120 vaccine candidates now being tested in lab dishes, animals and even humans, the finish line may be in sight. Some experts predict that a vaccine may be available for emergency use for the gen-eral public by the end of the year, even before it receives expedited U.S. Food and Drug Administration approval.
