Gayle King Shaken by False Positive COVID-19 Test

“It rocked me and surprised me,” said Gayle King about the scary moment she tested positive for COVID-19. The “CBS This Morning” co-host was absent for two days, until a battery of tests showed that it had been a false positive. Johnson & Johnson revealed that it has a new vaccine that is 72% effective, and will apply for emergency use authorization next week. It’s less effective than the other vaccines, which reach 95%, but doesn’t require a second shot or need to be kept at very low temperatures.
