Coronavirus immunity not assured after infection, WHO says, imperiling ‘passport’ idea

There is “currently no evidence” that people who recover from coronavirus are protected from a second infection, the World Health Organization wrote Friday in a scientific briefing.

The statement came as Chile announced plans to distribute “immunity passports” for recovering patients to use at workplaces, airports and other locations – and as officials in the U.S. and France expressed interest in similar plans, NPR reported.

The WHO’s statement would seem to negate the validity of any such document.

“Some governments have suggested that the detection of antibodies to the SARS-CoV-2, the virus that causes COVID-19, could serve as the basis for an 'immunity passport' or 'risk-free certificate' that would enable individuals to travel or to return to work assuming that they are protected against re-infection,” the WHO wrote. “There is currently no evidence that people who have recovered from COVID-19 and have antibodies are protected from a second infection.”

The information was sure to be troubling as the world continued grappling with the outbreak, which as of early Sunday had sickened more than 2.9 million people and killed more than 203,000 across the globe, according to Johns Hopkins University.
