Only 5.5 percent of Belgians have antibodies in blood: what does this say about the epidemic and about group immunity?

“Unfortunately, the antibodies we see only prove that the person has recently been in contact with the coronavirus,” said Professor Van Damme. “They don’t make us immune. Maybe there are other cells in our body that do, like killer T cells. But we don’t know enough about that at the moment.” In other words, it remains uncertain to what extent people who have already been infected are protected from the virus.
