Antibodies in Recovered COVID-19 Patients Fade Quickly, Study Says

[Northerner]

Antibody levels in the blood of coronavirus patients drop quickly after the body clears the virus, according to a new study published in mBio, an open access journal of the American Society for Microbiology.

For convalescent plasma to help patients who currently have COVID-19, the donated blood needs to be collected soon after recovery. Under current guidelines, however, patients can't donate blood until 14 days after symptoms have resolved, and most donations occur even later.

"We don't want to transfuse the virus, just transfuse the antibodies. But at the same time, our work shows that the capacity of the plasma to neutralize viral particles is going down during those first weeks," Andres Finzi, PhD, one of the study authors and a microbiologist at the University of Montreal in Canada, said in a statement.

Of course they do. What's the point of antibodies remaining when there's no disease? It's the T-Cells that remember infections, ready for the next time. I don't have any antibodies to measles, but I'm immune. Just imagine what we would be like if our blood contained antibodies to every illness we've picked up in life.

Mike, did I ever tell you how invaluable you are to this group? 🙂 You are 🙂

What Group is your antibody soup? Oh, it's AB+. What's yours?

I read somewheres that Type O's like me are more resistant and that Type A's etc go straight onto ventilators if they get it. Good grief. My daughter has a rare blood type and ignores the present situation like all those round her.

I suspect there is more to it than just blood group, I can't remember what group I am only that I am Rhesus Postive.

 

[Northerner]

Mine is B+, 'be positive!', my blood is telling me! 🙂

 

[mikeyB]

The vast majority of the Chinese population is Type O, so that kinda blows into the water about any relationship to blood type. Since the virus is completely inert, and can only reproduce in cells with a nucleus, blood type doesn't matter a toss, because red blood cells don't have a nucleus.

Furthermore, folk with infections don't get cross matched for blood, so nobody has the slightest clue who survives and who doesn't, by blood group, so the topic is simply an invention. I think if there was any truth in it, the government medics just might have mentioned it as a risk factor.

The biggest risk by far, not mentioned by the government (but well demonstrated by the PM), is stupidity.

You're making me blush. By the way, I''m B+ too.

I could imagine situations where you might be able to tell. (Amongst healthcare workers, for example: you'd have a chance of knowing blood type and who'd become infected and who'd then become sick. Or (eventually) participants in Biobank; you wouldn't know about those who haven't been tested for the virus but you'd be able to look at those who'd become sick with it.)

I'd guess someone would have noticed if there were a strong effect. https://jamanetwork.com/journals/jama/fullarticle/2770889 suggests that of the reports that there is an effect they disagree on the direction.

So I doubt it's worth worrying about. (And I won't worry that I have no idea what blood type I have.)

You restore my faith in mankind MikeyB, I'm so grateful for your expertise on this forum. Im tired of hearing the rubbish in the media, it's very misleading. It's leading people into thinking that vaccines are the only solution.

I posted this a while back, which confirms what you are saying.

How viruses and immunity actually works

Hi Everyone, I found this interview with an expert (Akiko Iwasaki, PhD) discussing the covid19 virus. Below is an extract of the interview. It basically confirms that all the current publicity about people not showing long term anitbody immunity is not the whole story. Even though the...
