'No evidence' that recovered COVID-19 patients cannot be reinfected: WHO

The World Health Organization (WHO) said on Saturday that there was currently “no evidence” that people who have recovered from COVID-19 and have antibodies are protected from a second coronavirus infection. In a scientific brief, the United Nations agency warned governments against issuing “immunity passports” or “risk-free certificates” to people who have been infected as their accuracy could not be guaranteed.
