There’s no evidence that people who’ve had COVID-19 are immune: WHO
NATIONAL | APRIL 26, 2020:
World Health Organization (WHO) has said that there is currently no evidence that people who have recovered from COVID-19 and have antibodies are protected from a second infection.
It suggests that the issuance of "immune passports" may promote the continued spread of the pandemic.
WHO said no study has evaluated whether the presence of antibodies to SARS-CoV-2 confers immunity to subsequent infection by this virus in humans.
WHO said there is still a lack of sufficient evidence for the effectiveness of antibody-mediated immunity to guarantee the accuracy of an immunity passport or risk-free certificate.
According to the UN agency, laboratory tests that detect antibodies to SARS-CoV-2 in people, including rapid immunodiagnostic tests, need further validation to determine their accuracy and reliability.
