A panel of scientists takes a closer look at potential problems involving immunity passports as a means to end the coronavirus lockdowns for those who have been infected and recovered. Multiple countries are looking to enact this plan, but important questions remain to be answered, or even discussed.

How long do antibodies last? Could immune people still infect others? Could such passports be forged or would cell phone apps and a digital tracking system be used for enforcement? What are the civil liberties implications for those who’ve complied with lockdowns and avoided infection?
