The World Health Organization discouraged governments from handing out immunity passports. They said there isn’t any evidence that recovered COVID-19 patients won’t contract it again. According to Business Insider, the WHO said it’s too early to see if they develop antibodies that give them immunity. They said: "People who assume that they are immune to a second infection because they have received a positive test result may ignore public health advice." The Who said if governments begin to hand out “risk-free certificates,” it might “increase the risks of continued transmission.”
