Immune System Has Long-Term Defenses After Mild COVID-19

Immune system has long-term defenses after mild COVID-19; children may be key carriers of virus variants

...Months after recovery from mild COVID-19, when antibody levels in the blood have declined, immune cells in bone marrow remain ready to pump out new antibodies against the coronavirus, researchers reported on Monday in Nature. Upon infection, short-lived immune cells are generated quickly to secrete an early wave of protective antibodies. As the immune cells die out, antibody levels decline. But a pool of these immune cells, called long-lived plasma cells, is held in reserve after infection. Most of them migrate to the bone marrow, explained coauthor Ali Ellebedy of Washington University School of Medicine in St. Louis. His team obtained bone marrow samples from 19 patients seven months after the onset of mild COVID-19. Fifteen had long-lived plasma cells secreting antibodies against the coronavirus. Five of the 15 had second bone marrow biopsies 11 months after symptom onset and all still had long-lived plasma cells secreting antibodies against SARS-CoV-2. Ellebedy, in a statement, noted that these cells are "just sitting in the bone marrow and secreting antibodies. They have been doing that ever since the infection resolved, and they will continue doing that indefinitely... These cells will live and produce antibodies for the rest of people's lives." It is not clear yet whether the same results would be seen in survivors of moderate to severe COVID-19, the authors said...

Oh, yeah. I wouldn't count on universal school reopening for in-person instruction either...

...Young children appear to be significant carriers of more contagious variants of the new coronavirus, such as the ones identified in the UK and in California, according to a new U.S. study. From March 2020 to April 2021, researchers at nine children's hospitals tested a total of 2,119 COVID-19 patients age 18 or younger for so-called variants of concern, along with key mutations that help the variants become more contagious or hide from the patient's immune system...

I wonder if those children's hospitals are the same ones who were found to have inflated the number of children's cases during the pandemic as noted in the article I posted recently.

LOL ours have been open full capacity since September and for the last month without masks. My son who has been managing a local test station will be unemployed as of next Wednesday. This thing is over.

Now, now. We must follow 'the science' and 'the science' says that children are going to spread the mutations and since the vaccines aren't as effective against the mutations, despite what 'the science' claims, we must acknowledge that 'the science' says that the schools can't reopen and the unions agree. Mutations are 'the next wave' according to 'the science.' Haven't you been paying attention?

Insofar as having a long-term, natural immunity if you've had a mild case of COVID, 'the science' says you must have a vaccination to gain temporary immunity and 'the science' says that even if you've had it you need the vaccine for said temporary immunity. So, regardless of 'the science' that says you have long-term immunity, in the short-term, 'the science' says you still need to take the vaccine; i.e., clearly, there is a difference between long-term and short-term immunity. Don't you understand basic 'science?' You must be a Trump voter... that's it. Just ignorant insofar as 'the science.'

Don't you get it? I mean, that's the way the whole messaging has come across for over a year. One would think you'd understand it by now. Sheesh.

yes, I completely understand. BTW, thank you for answering my long sought after question about whether my bodies immune system is better than the jab.

But Dr. Fauci said to get the jab...
