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-191.
The study provides evidence that immunity triggered by SARS-CoV-2 infection will be extraordinarily long-lasting. Adding to the good news, “the implications are that vaccines will have the same durable effect,” says Menno van Zelm, an immunologist at Monash University in Melbourne, Australia.
Antibodies — proteins that can recognize and help to inactivate viral particles — are a key immune defence. After a new infection, short-lived cells called plasmablasts are an early source of antibodies.
But these cells recede soon after a virus is cleared from the body, and other, longer-lasting cells make antibodies: memory B cells patrol the blood for reinfection, while bone marrow plasma cells (BMPCs) hide away within bones, trickling out antibodies for decades.
“A plasma cell is our life history, in terms of the pathogens we’ve been exposed to,” says Ali Ellebedy, a B-cell immunologist at Washington University in St. Louis, Missouri, who led the study, published in NATURE on 24 May.
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’ formation2. Some early COVID-19 immunity studies also stoked worries, when they found that antibody levels plunged not long after recovery3.
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.

Oh… like EVERY OTHER FLU VIRUS EVER?!
this was total BS from the start.
There should be a monthly booster.
It can’t be!
How will the big-government/big-pharmaceutical criminal complex cash in it is?
Now they have a lottery for a million dollars. Ironically you have the same odds of dying from it as winning.
is it possible to get tested for antibodies?
serious question
“this was total BS from the start.”
Right. Had it not been election year with another term looming in the future, we’d have heard about Covid-19 for maybe a month.
I believe that Fauci — an emissary of his true-love Hillary and other left-wing activists — was complicit in this. He invented the lethality of the virus via his ghoulish gain-of-function weaponization of Covid. That is common knowledge now. Then he conspired with his Chinese friends to see that it was “gifted” to the world. (After they all knew it was lethal, Chinese were schlepped via planes everywhere, on purpose. They even brought the cooties to a White House meeting, knowing it would bring infection.)
It’s a high price to pay for the left to rationalize massive voter fraud, but it was worth it to them.
Just talked to a gf and she said she was sick for weeks after taking both shots; she said she wished she didn’t take them.
Can the same be said about the next manufactured virus? They aren’t done yet.
Now imagine what would have happened if herd immunity was reached quite some time ago if we didn't have this 15-day, err 1+ years, of flatten the curve bullshit that destroyed the economy. I wonder if fewer people with comorbidities would have died if the CCP virus just spread among the healthy where most would just feel crappy for a few a days.
RE: is it possible to get tested for antibodies?
Of course. A COVID-19 antibody test, also known as a serology test, is a blood test that can detect if a person has antibodies to SARS-CoV-2.
Consult your doctor. You have to be willing to pay for it though.
The serology tests for antibodies for SARS-CoV-2 may not help with the latest push to treat the variants as distinct threats. I don’t know if the current serology tests are variant specific.
So. With all these studies popping up everywhere, can those of us who fought the dragon and won get a card like those who got jabbed? It appears our immunity is at least as good. Seems only fair....
There's T-Detect; and there are far more granular (expensive) blood tests like ELISA serology testing; and if you're a cheapazz, supposedly the Red Cross is testing for previous COVID exposure when becoming a donor.
You'll have to google them, I'm not offering links in any SeekAndFind thread.
The strange thing is that the common cold is also a corona virus, but we don’t develop immunities from it.
While it’s called sars cov2, a doc told me that it’s actually a second round of sars.
I remember a few years ago how people panicked with sars. Were immunities ever developed from it?
For life! Did you hear that? FOR LIFE! No more masks! No more distancing! Eat with everyone at the Thanksgiving dinner table! For life! I’m all in.
