"Professor Katrien Lagrou, head of the clinical microbiology lab at UZ Leuven, confirms that the tests on the market in Belgium are reliable." I prefer to speak of an antibody test rather than an immunity test, "she says. "Even if antibodies are found in someone who has been infected, it doesn't mean that that person is actually immune to the virus."
No antibodies were found in Soubry's blood. "That is probably because he was not ill and therefore the virus went through asymptomatic," the professor continues. ,, Previous studies on antibodies have been done in patients who have been seriously ill and have been hospitalized. This showed that the vast majority had indeed built up antibodies. In any case, the results are limited: in general very few people have been tested. ”
So it may be a coincidence that Soubry is not immune, she concludes. ,, But it is equally possible that those who have never had a fever or have never been seriously ill, like he, have never developed antibodies and can therefore be carriers a second time. It seems very unlikely that he once produced antibodies and that they would have disappeared from his body by now. No one knows for sure. A lot of research still needs to be done. ”
