The media is finally admitting after 15 months of spreading wild hysteria and misinformation that people who catch the coronavirus are probably immune for years if not for life, at least for similar strains.
“Had COVID? You’ll probably make antibodies for a lifetime,” reads a headline from Nature published Wednesday.
Many people who have been infected with SARS-CoV-2 will probably make antibodies against the virus for most of their lives. So suggest researchers who have identified long-lived antibody-producing cells in the bone marrow of people who have recovered from COVID-19.
The study provides evidence that immunity triggered by SARS-CoV-2 infection will be extraordinarily long-lasting. […]
Researchers presumed that SARS-CoV-2 infection would trigger the development of BMPCs — nearly all viral infections do — but there have been signs that severe COVID-19 may disrupt the cells’ formation. Some early COVID-19 immunity studies also stoked worries, when they found that antibody levels plunged not long after recovery.
Ellebedy’s team tracked antibody production in 77 people who recovered from mostly mild cases of COVID-19. As expected, SARS-CoV-2 antibodies plummeted in the four months after infection. But this decline slowed, and up to eleven months after infection, the researchers could still detect antibodies that recognized the SARS-CoV-2 spike protein.
To identify the source of the antibodies, Ellebedy’s team collected memory B cells and bone marrow from a subset of participants. Seven months after developing symptoms, most of these participants still had memory B cells that recognize SARS-CoV-2. In 15 of the 18 bone-marrow samples, the scientists found ultra-low but detectable populations of BMPCs whose formation had been triggered by the individuals’ coronavirus infections 7 to 8 months before. Levels of these cells were stable in all five people who gave another bone-marrow sample several months later.
How many epidemiologists and others were called “conspiracy theorists” and banned from the internet for saying this over a year ago?
