The number of anti-bodies against the Coronavirus was measured with Roche Elecsys Electrochemiluminescence Immunoassay, qualitative detection of total anti-bodies developed against the virus in people’s blood samples before and after the vaccination period said the research group.

Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a kind of luminescence produced during electrochemical reactions in solutions.

The tests were conducted before injections, three weeks after the first shot and four weeks after the second injection.
