Earlier today we tweeted about a new WHO scientific brief on “immunity passports”. The thread caused some concern & we would like to clarify:
We expect that most people who are infected with #COVID19 will develop an antibody response that will provide some level of protection. pic.twitter.com/AmxvQQLTjM

“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,” said WHO, adding: “There is currently no evidence that people who have recovered from COVID-19 and have antibodies are protected from a second infection.”
