Pandemic – Already 64,000 certificates established with a serological test

Posted

Since November 16, a Covid certificate, valid for 90 days, has been issued for people with enough antibodies. Experts doubt their reliability.

A few drops of blood are used to determine the level of antibodies.

The FOPH confirms this. Since November 16, 64,759 people have received a Covid certificate, valid for 90 days, after having undergone a serological test. These people have therefore contracted the disease and are “immune”. They can participate more easily in public life. Nothing to do with the certificate given to people who had a positive PCR test and who overcame the disease. In total, 482,000 people have this type of certificate.

Today, an antigen test costs between 50 and 80 francs. Problem: International research has not set a limit value above which a person with detected antibodies is considered to be protected against infection. The Swiss Microbiology Society says that “the detection of antibodies does not guarantee protection against infection or serious development.” As a result, each laboratory can set itself the limit from which such a certificate is issued. Experts are therefore asking for standards.
