Longterm Covid-19 antibody protection?

[Valknor]

Here's an interesting article about longterm antibody protection for those who have recovered from Covid-19.

“Last fall, there were reports that antibodies wane quickly after infection with the virus that causes COVID-19, and mainstream media interpreted that to mean that immunity was not long-lived,” says senior author Ali Ellebedy, associate professor of pathology and immunology, of medicine, and of molecular microbiology at Washington University in St. Louis.

“But that’s a misinterpretation of the data. It’s normal for antibody levels to go down after acute infection, but they don’t go down to zero; they plateau. Here, we found antibody-producing cells in people 11 months after first symptoms. These cells will live and produce antibodies for the rest of people’s lives. That’s strong evidence for long-lasting immunity.”
