Recent study looked at bone marrow samples of those who had a relatively mild case of COVID and recovered to see if there were antibody-producing cells there that could rapidly respond to the threat of another infection. It turns out that there were, in most of them, even after 11 months. Antibody testing is not a good way to determine whether someone has immunity, as antibodies fade rapidly after the infection has been suppressed. Beyond that point, the T cells (which can attack and kill viruses) and B cells (which manufacture antibodies) reside mostly in the bone marrow.
I'm not surprised by this, as it supports the findings of several other recent studies re. virus-induced immunity to COVID. This is exactly how our immune systems respond to many viral attacks, especially serious viral threats like SARS-Cov-1 (another coronavirus). People who had SARS still have strong immunity to it some 18 years later. I think the media is just now starting to catch up to the science on this.
