IF ANTIBODY AGAINST EVERY PATOGEN IS PRODUCED, BLOOD TURNS INTO A THICK MUD
To look at new types of coronavirus-specific memory B cells, researchers led by Ali Ellebedy of Washington University analyzed the blood of 77 people at three-month intervals, starting about one month after the corona virus infection. Only six of 77 people were hospitalized due to Covid-19; the rest were stated to have mild symptoms.
Antibody levels in these individuals dropped rapidly four months after infection. It continued to fall slowly over the following months. Some scientists interpreted this drop as a sign of decreased immunity, but other experts said it was exactly what was expected. Because if the blood produced large amounts of antibodies against every pathogen the body encounters, it would quickly turn into a thick mud.
