Hungarian Swimmers Who Tested Positive For Coronavirus Devoid Of Antibodies

A group of Hungarian swimmers who tested positive for the coronavirus have not shown antibodies in their blood after analysis of samples by a research group.

As we reported in March of this year, nine people affiliated with Hungarian Swimming, including National Team swimmers and staff members, tested positive for coronavirus while partaking in training camps.

Dominik Kozma, David Horvath, Richard Bohus, and Boglarka Kapas were among them but were asymptomatic.

After the aforementioned eventually tested negative and were able to return to training, they donated plasma at the University of Physical Education in Budapest. As we reported, the facility is in cooperation with Semmelweis University and the Virology Research Group of the University of Pecs and OrthoSera Kft. developing plasma therapy.

Per the American Red Cross at the time, people who have fully recovered from COVID-19 were thought to have antibodies in their plasma that can attack the virus. This convalescent plasma is being evaluated as a treatment for patients with serious or immediately life-threatening COVID-19 infections, or those judged by a healthcare provider to be at high risk of progression to severe or life-threatening disease.

Months later, however, the swimmers’ blood donations were analyzed by researchers at the University of Pecs, with the scientists finding no coronavirus antibodies in the samples. In fact, according to an interview with researchers published in Hungary Today, only 1 of 29 prominent Hungarian athletes who donated blood had the coronavirus antibodies contained within it after contracting the disease.

These findings correlate to those rendered in a Chinese study performed in June as well. As published on the University of Minnesota’s Center for Infectious Disease Research and Policy site, 90% of 74 participants, both asymptomatic and symptomatic showed steep declines in levels of SARS-COV-2–specific immunoglobulin G (IgG) antibodies within 2 to 3 months after onset of infection. Further, 40% of the asymptomatic group tested negative for IgG antibodies 8 weeks after they were released from isolation.

There is still hope that those infected with the virus will show a strong T-cell-mediate response, which is another potential form of immunity, as early studies, including one done by the Karolinska Institute, have indicated that T-cell responses have been more common than antibody responses. It is not clear yet, though, how much immunity those T-cell responses will confer, as research is ongoing.

T-cell mediation. Lots of studies coming out showing that a large % of sampled individuals have that.

This is correct!

Here is Dr. Sikora talking about this very thing. Highly respected in his field:

Explain this to me like I’m 5

I’ll explain it to you like you’re 14. They studied the blood of Hungarian athletes who had tested positive for coronavirus, and didn’t find the antibodies that they thought they would a few months down the road. This indicates either that they were all mis-diagnosed (unlikely), or that this kind of antibody immune response doesn’t last very long. As DrSwimPhil brought up, there is some hope for T-Cell Mediation, which is an immune response that doesn’t involve antibodies, but the science is still out there too as to whether it will provide protective immunity. As with everything coronavirus, the science is moving very rapidly. It probably won’t become clear what this all means for another month or two when there… Read more »

>or that this kind of antibody immune response doesn’t last very long.

Or that totally asymptomatic cases, as in this case with swimmers, do not make antibodies at all.

That article you reference also states”

But evidence from a June study in Spain indicated that antibodies may only last for two or three months. In a separate study published this week in the Lancet, a medical journal, researchers found that people who had been infected often shedded antibodies from the virus after only a few weeks.

So back to your first statement.

Why is psychodad also fearmongerdad? This virus is overblown.

Posted this on twitter 2 hours ago:

My oldest son lives in Denver. Yesterday, one of his friends died from coronavirus. He was 30 and no pre-conditions. Went to Arizona, came back, felt sick, checked into hospital 2 weeks ago, and died yesterday.

No, not a fearmongerdad (but you can think whatever you want), just concerned with amount of stupidity in this country. Freedom is not going to Costco and yelling at a grandma that asks you to wear a mask – freedom is state of mind that minority of Americans have.

Sorry to hear about your sons friend. I don’t think anyone is claiming that nobody under the age of 30 has died from Covid, but of the 135,000 deaths less than 1000 have come from those 34 years of age or younger.

Here we go again…

Nice explanation. Now please explain Covid testing to Trump….he seems to have a problem understanding it. 😜

PARTICIPANT RIBBON

Of course if you want to go down that path……if you explain it to Biden, please do so daily because he may not remember.

Not good for heard immunity.

Is that like when you heard you had immunity so you assumed it was true?

Xman

Yes I heard that people people who had it have immunity, and now I’m hearing they don’t 😉

AfterShock

That’s unheard of.
