My 72 year old chain smoking neighbor. Yes. You are - reading it correctly. Two weeks ago,

Posted: Apr 5th, 2020 - 6:33 am In Reply to: Same with me, right before Christmas. I attributed it - to sinusitis. I recovered. I also

he was sent home to die because the hospital rant out of respirators. Chest pains were intense and he slept it off...for 5 days. 6th day the fever broke. Went back to the same stupid hospital which left him for dead and tested negative.

Now they are BEGGING him to donate plasma. I kid you not.

Interesting history of "Convalescent Plasma" therapy published three days ago at...
Before Vaccines, Doctors ‘Borrowed’ Antibodies from Recovered Patients to Save Lives
The very first Nobel Prize in Physiology and Medicine was awarded in 1901 to Emil von Behring for his life-saving work developing a cure for diphtheria, a bacterial infection that was particularly fatal in children. His groundbreaking treatment, known as diphtheria antitoxin, worked by injecting sick patients with antibodies taken from animals who had recovered from the disease.

Von Behring’s antitoxin wasn’t a vaccine, but the earliest example of a treatment method called “convalescent plasma” that’s being resurrected as a potential treatment for COVID-19. Convalescent plasma is blood plasma extracted from an animal or human patient who has “convalesced” or recovered from infection with a particular disease.

“Convalescent plasma has been used throughout history when confronting an infectious disease where you have people who recover and there’s no other therapy available,” says Warner Greene, director of the Center for HIV Cure Research at the Gladstone Institutes. “There must be something in their plasma—i.e. an antibody—that helped them recover.”

Convalescent plasma interacts differently with the immune system than a vaccine. When a person is treated with a vaccine, their immune system actively produces its own antibodies that will kill off any future encounters with the target pathogen. That’s called active immunity.

Convalescent plasma offers what’s called “passive immunity.” The body doesn’t create its own antibodies, but instead “borrows” them from another person or animal who has successfully fought off the disease. Unlike a vaccine, the protection doesn’t last a lifetime, but the borrowed antibodies can greatly reduce recovery times and even be the difference-maker between life and death.

“Convalescent plasma is the crudest of the immunotherapies, but it can be effective,” says Greene.

It's amazing that the history of convalescent plasma goes all the way back to the 1890s. It's equally amazing that the researchers at the time thought to remove the blood cells from blood leaving behind the plasma.
