Phelan, SJD, LLM, LLB, an assistant professor at Georgetown University Medical Center and a faculty member of its Center for Global Health Science and Security, writes that immunity passports "create an artificial restriction on who can and cannot participate in social and economic activities," warning that this creates "a perverse incentive for individuals to seek out infection." > "Immunity passports would be ripe for both corruption and implicit bias" and would "exacerbate the harm inflicted by COVID-19 on already vulnerable populations," Phelan argues. And she adds that the people "most incentivised to seek out infection might also be those unable or understandably hesitant to seek medical care due to cost and discriminatory access."
