Even mild COVID-19 may induce long-lasting antibody response

https://www.upi.com/Health_News/2021/05/25/coronavirus-mild-disease-long-lasting-antibodies-study/4941621947156/

Mild cases of COVID-19 leave people with long-term antibody protection against reinfection, according to a new study that challenges previous findings.

"Last fall, there were reports that antibodies wane quickly after infection with the virus that causes COVID-19, and mainstream media interpreted that to mean that immunity was not long-lived," said study senior author Ali Ellebedy, an associate professor of pathology and immunology, medicine and molecular microbiology at Washington University School of Medicine in St. Louis.

"But that's a misinterpretation of the data. It's normal for antibody levels to go down after acute infection, but they don't go down to zero; they plateau," Ellebedy said in a university news release. "Here, we found antibody-producing cells in people 11 months after first symptoms. These cells will live and produce antibodies for the rest of people's lives. That's strong evidence for long-lasting immunity."

The study included 77 people who were giving blood samples at three-month intervals starting about a month after initial infection with COVID-19.

Most had had mild cases of COVID-19, and only six had been hospitalized.

Interesting, on a couple of points.

First, it is axiomatic that people who get a mild case of chicken pox are susceptible to getting it again. Evidently immune system response to SARS-CoV-2 is less dependent on the severity of the case.

Second, this study extends the duration for which antibodies are known to persist. SARS-CoV-2 has been in the US for less than 18 months, so we probably cannot know how long the antibodies will persist, nor how long recovered people's immune systems "know" how to recognize and produce antibodies against the virus. There is a corresponding "unknown" wrt antibodies produced via vaccines.

Immunity to the coronavirus lasts at least a year, possibly a lifetime, improving over time especially after vaccination, according to two new studies. The findings may help put to rest lingering fears that protection against the virus will be short-lived.

Together, the studies suggest that most people who have recovered from Covid-19 and who were later immunized will not need boosters. Vaccinated people who were never infected most likely will need the shots, however, as will a minority who were infected but did not produce a robust immune response.

Both reports looked at people who had been exposed to the coronavirus about a year earlier. Cells that retain a memory of the virus persist in the bone marrow and may churn out antibodies whenever needed, according to one of the studies, published on Monday in the journal Nature.

The other study, which is also under review for publication in Nature, found that these so-called memory B cells continue to mature and strengthen for at least 12 months after the initial infection.

“The papers are consistent with the growing body of literature that suggests that immunity elicited by infection and vaccination for SARS-CoV-2 appears to be long-lived,” said Scott Hensley, an immunologist at the University of Pennsylvania who was not involved in the research...

They haven't been distributing vaccines for a year.  So, how do they have verifiable, peer-reviewed, empirical data to base this on?

The New York Times ... all the news that's fit to line bird cages and wrap fish.

Yes, there are two studies mentioned in the article. This one has already been published:

https://www.nature.com/articles/s41586-021-03647-4

The second one is currently under review. The fact that the article is in the NY Times is irrelevant. It's just quoting peer-reviewed studies.

Easy. Testing of the Moderna vaccine began in March 2020, over a year ago. Testing of the Pfizer vaccine began in April 2020, also over a year ago. If you want the exact dates, go here https://www.gopbriefingroom.com/index.php/topic,412701.0.html . Participants in those tests are still being followed.

COVID-19 reinfection found in 2% of university students
In the spring 2021 semester, 2.2% of Clemson University, South Carolina, students previously infected with COVID-19 were diagnosed as having been reinfected, according to a study published yesterday in Clinical Infectious Diseases.

Sure, as you do with any disease. You need to look at probabilities not existence of exceptions to the rule.

1 in 50 is a pretty high rate of exceptions.

Studies: If you had COVID and then got vaccinated, you're basically Superman

Does this mean … Rand Paul was right? Last week he said that he has no plans to be vaccinated, having recovered from a mild case of COVID 13 months ago. Scientists criticized him for that, warning that there was no reason to think his natural immunity would last indefinitely. Now suddenly here’s evidence that his protection from the virus may be stronger than those scientists thought.

I think he’s half-right. Yes, natural immunity looks solid, at least for 12 months. Vaccine immunity does too. But natural immunity plus vaccine immunity? You might as well walk around in a cape and tights.

The lady giving me my second dose didn't mention the cape and tights. Maybe they'll come in the mail next week when I'm "officially" fully vaccinated?

  I promise I won't take a picture and use it for my avatar.

Already got Moderna, but now you got me thinking about taking advantage of the Pfizer vax they are offering at my employer. I could really put that x-ray vision thing to good use.

Right.  That's what they're claiming this week.  Next week will be a different story.

Uh, no.  The new study affirms previous findings.

It's not just whether you get the virus, but how bad it is when you do. For example, the Pfizer and Moderna vaccines have 95 and 94% efficacy, if I remember correctly. But of the tens of thousands of people in the initial trials, the subset of those in that 5-6%, none of them had serious cases of COVID. So some still get it, but they don't have to be hospitalized.

These vaccines are new, but vaccinations aren't, and there isn't anything special about COVID that means we have to throw out everything we know about vaccines and the immune system. Some in the media see advantage in scaring people, and so absent any conclusive studies, they've been hyping up a hypothetical worse case. Well, now we have studies, and we can see the media is full of shit.

Thousands of USA citizens are dead today because of our corrupt media.  The moment Trump suggested Hydroxy was instrumental in helping people early, the media defamed the drug.  Their rhetoric killed thousands, perhaps hundreds of thousands.

Trust the media at your peril!!!

My wife and I have had COVID twice.  First time was the first week in January, 2020, before any testing existed.  We both had the COVID symptoms.  It took me a long time to recover from it.  My wife, 20 years younger was not nearly as affected.  Then we had it again about three months ago.  Got tested, and it proved what we already knew.  2nd time, I was a week in bed, just like the first time.  I was probably more fearful 2nd time because of all the news we absorbed for a year.  However, 2nd time I recovered faster.  My taste however did not come back for about a month.

Interestingly, we are both sick again.  She is an infectious disease physician and she believes we have an adeno virus.  No fever this time.  Sore throat, and slight cough and mild congestion.  It has lingered for 2+weeks for me, and she is finishing her 1st week.  This time, she was more adversely affected than me.

I anticipate a huge number of folks getting sick with other viruses when the masks come off and people relax on washing hands, etc.  Hand washing is very important.  Every time we leave the house and return, we wash our hands.

And it's not as if Trump made it up either.  Trump was merely repeating the decade-old conclusions of NIH after the SARS-1 epidemic.

ALL MSM coverage of Covid in 2020 and well into 2021 has to be understood as having been filtered through Orange Man Bad.
