FSVO/Renate Boss - A Swiss-German team presents a test that determines the amount of neutralising antibodies within a short period of time. The test was developed at the Institute of Virology and Immunology (IVI) of the University of Bern and the Swiss Federal Office for Food Safety and Animal Health, and evaluated in cooperation with colleagues from the Ruhr-University Bochum using serum samples from COVID-19 patients. To determine immunity to SARS-CoV-2 and the effectiveness of potential vaccines, the amount of neutralising antibodies in the blood of recovered or vaccinated individuals must be determined. A traditional neutralisation test usually takes two to three days and must be carried out with infectious coronaviruses in a laboratory complying to biosafety level 3. A Swiss-German research team from Bern and Bochum has launched a test that takes only 18 hours and doesn't have high biosafety requirements. The researchers have published their report in the journal "Vaccines" on 15th of July 2020.
