WHO, 코로나19 '면역 증명서'은 정확성 보장 못해.
The World Health Organization said Friday that there's not enough evidence to prove that the presence of antibodies for COVID-19 protects people from a second infection, and so it's too soon to go ahead with the idea of an "immunity passport" or "risk-free certificate."
So-called immunity passports have been proposed by some countries as a way to enable people to travel and to reopen their economies.
The WHO said, however, that it will continue to review antibody responses to COVID-19 infection.
Some countries, including South Korea, have reported cases of people testing positive for the virus after having apparently recovered.
