1/6 In Gavroche on 3 May I envisaged a "predictable overcoming of the reservations on the individual use of serological tests" to identify those who have had COVID-19 and to evaluate their immunity by testing for antibodies in their blood. bit.ly/2L7sNR6 #SamRainsy
2/6 The WHO had warned that it’s "uncertain that the antibodies present at a given moment can give protection against a new infection by the same virus in the future”.
3/6 This warning opened a debate on the possibility of the same person recontracting the same virus within a relatively short period. Such a hypothesis on the absence of immunisation would lead to conclusions that would be both irrational and catastrophic.
4/6 I noted that the WHO based its warning on a few cases observed in China and South Korea.
5/6 The WHO has since clarified that these results in South Korea weren’t reinfections, but in fact tests which gave ‘false positives’ because of dead cells containing fragments of the virus".
6/6 Étienne Decroly, director of research at France’s CNRS National Center for Scientific Research, described it as “very good news.” #SamRainsy #COVID19 #immunitypassports
