Some people who havenít had COVID-19 could already have some immunity; hereís why

The study, published in the journal Nature on Wednesday, found that among a sample of 68 healthy adults in Germany who had not been exposed to the coronavirus, 35% had T cells in their blood that were reactive to the virus.

T cells are part of the immune system and help protect the body from infection. T cell reactivity suggests that the immune system might have had some previous experience fighting a similar infection and may use that memory to help fight a new infection.

So how could their immune system have reactive T cells if they never had Covid-19? They were “probably acquired in previous infections with endemic” coronaviruses, the researchers — from various institutions in Germany and the United Kingdom — wrote in the new study. Using this T cell memory from another-yet-similar infection to respond to a new infection is called “cross-reactivity.”

While the researchers also found pre-existing cross-reactive T cells in the healthy donors, they wrote in the study that the impact those cells might have on the outcome of a Covid-19 illness still remains unknown.

‘Are people who have severe disease less likely to have cross reactive T cells versus people who have mild disease maybe having more cross reactive T cells?’ I think that there’s biological plausibility to that hypothesis,” he said. “It’s clear though that the T cell presence doesn’t prevent people from getting infected, but does it modulate the severity of infection? That’s what it appears could be the case.”

There’s nothing surprising about this. The first vaccine was called a “vaccine” because Edward Jenner noticed that milkmaids who got the relatively mild cowpox seemed to not be dying from smallpox. So he tried infecting people with cowpox to prevent dying of smallpox and it worked.

You can’t be sure these people haven’t had a mild case of Covid-19, maybe with no symptoms. Their t-cells may have fought it off quickly.

In other words, having had certain colds in the past may have conferred some immunity.

May use that memory? May? The very essence of our immune system is that it is constantly learning.

That is why we do not see a lot of dead homeless people. They were expose to some coronavirus on the dirty streets in the past that gives them some immunity today.

That is what they need to do, but they will not because of the big drug companies. I think zinc sulfate might be, not sure.

People here were seeing the doctors for an “unidentified respiratory virus” between December and February before COVID was in the news. I personally had the strangest bout of bronchitis in February that I have ever had. I have asthma so if my allergies get really bad it turns into bronchitis. In February I had allergies with a splitting headache and figured the allergies caused the headache and severe stomach pain/reflux that plagued me for 3 days or so. After a few days of that I started coughing a dry cough. Did that for a couple of days and got a sore throat. I called the doctor at that point since COVID was here. She asked if I had a fever and I told her “no”, that I thought it was my regular bronchitis. She prescribed a z-pak and Prednisone. After two days the sore throat disappeared and I had a wet gurgling cough. She called in two prescription cough meds. It got pretty rough for a while but my asthma didn’t really flare that much except for the dry cough when it first started.

It took over a month before I felt better and I still have a mild cough. Of course now it’s allergy time again and allergies always trigger my asthma and a cough. Allergies seem to always be bad in TN.

One of the only symptoms of COVID I didn’t have was a fever, and I’m still alive. :-)

I can’t help but feel sometimes that what is going around is the same unnamed illnesses that always go around but no reason to take a chance.

You may not have had COVID, but every one who has lived on this planet for more than a few years has already been infected with a coronavirus and survived.

Drug dealers...I can visualize many getting this drug from them if it’s not available.

That is funny, I was just thinking that. If there is a market it could happen.

That’s a fun thing to learn, but you are expecting a lot of linguistic insight of the average reader saying “that’s why they call it a vaccine.” If I may help put it more accessibly, thats why the Latin root word for vaccine is the same as the root word for Spanish vaca “cow”.

Maybe you have to be a Texan but it seems like everybody knows that.
