Dividing the world between the vaccinated and unvaccinated raises daunting political and ethical questions. Vaccines go overwhelmingly to rich countries and privileged racial groups within them. Granting special rights for the vaccinated, while tightening restrictions on the unvaccinated, risks widening already-dangerous social gaps.
Vaccine skepticism, already high in many communities, shows signs of spiking if shots become seen as government-mandated. Plans also risk exacerbating Covid nationalism: sparring among nations to advance their citizens’ self-interest over global good.
“Immunity passports promise a way to go back to a more normal social and economic life,” Nicole Hassoun and Anders Herlitz, who study public health ethics, wrote in Scientific American. But with vaccines distributed unequally by race, class and nationality, “it is not obvious that they are ethical.”
Still, there are clear upsides: grandparents reuniting with out-of-town grandchildren; sports, concerts and other events partly but safely returning; resumption of international travel and some tourism; businesses reopened without putting workers at undue risk.
