I’m one of the fortunate people who is yet to test positive for Covid. This is despite the fact that I work with live replicating Sars-CoV-2 (the virus that causes Covid) for my research, teach face-to-face at university, and have school-age children.
My fully vaccinated healthy friends of the same age were not so lucky, and some have suffered from more than one case of Covid in the past couple of years. What does this reveal about my immune system?
First, we have to consider a number of scenarios. There is a very small chance that I have never come into contact with the virus. But given the duration of the pandemic, and the number of highly transmissible variants, this is unlikely. Then there is the chance that I have come into contact with Sars-CoV-2, but it was cleared from my body quickly before it developed into the disease Covid (abortive infection). At the start of the pandemic, and before I was vaccinated, I could have caught the virus but I could have been one of the small number of people who did not display symptoms and therefore did not test for it.
Some people may clear the virus quickly because they have pre-existing antibodies and memory immune cells that recognise the virus. These could be cross-reactive memory T-cells generated previously to fight similar coronaviruses that cause the common cold. There is evidence of higher prevalence of endemic (non-Covid) coronavirus infections in the young and reduced cross-reactive T-cell presence in older people.

“He says that his job was to treat sick patients not to study well ones and why they stayed well.”
If only we would study the ones who haven’t gotten sick, we might know more about how to treat the sick or prevent people from getting sick.
I was just telling that to somebody today! “You know, on those cruise ships, everyone crowded together before they even knew about the virus, it was something like only 20% got sick. So the odds were good you were never going to get it anyway. Somebody should do a study about those ships.”
I never got it because I never gave a damn about getting it or not. My wife got it. The kids in my house got it. I was around all of them. I wasn’t walking around my house masked up.
Stayed away from some places ‘cuz they were closed up.
Masked up other places only because I was TOO damned close to the ragged edge of my Give-A-Damn bandwidth to be certain I wouldn’t actually double up and straight punch the ever-loving leftism out of anybody who accosted me for not having one.
I.
AM.
SO.
DONE.
And this utter !@#%#$ has not EVEN ended a moment too soon.
“If only we would study the ones who haven’t gotten sick, we might know more about how to treat the sick or prevent people from getting sick.”
My son and I both got the china flu. My wife skated by, fortunately. She has been on supplemental vitamin D for several years, might be something to that. She has her D level checked several times a year and sees her doctor to go over the test results. When the doctor heard about her close encounter with the virus she asked offhandedly asked my wife what her blood type was. The doctor said she asked every patient that was in a similar situation an didn’t catch it the same question. Turns out they all had the same blood type, which I suffer from CRS and don’t recall what it is, but I think it’s a rare type.
Might be something to the blood type theory but it’s contrary to my way of thinking when you figure many more didn’t catch it than did. Doesn’t fit with rare.
now, I was very sick late 2019 with every virus symptom you can think of, with fatigue and low grade fever, among others....perhaps we all had cases of early covid and never knew it...
OTOH, we are careful, and we take our vitamins religiously.....
I worked on a covid floor, not directly with them, but on the same floor among them.....so I know I've been around the virus....
I believe they did it's just that the results were never widely distributed. The Diamond Princess was an almost a perfect study in the rate of infection and death.
I call it tribal immunity.
Some of us come from very sturdy stock.
I think about Rosalyn and Jimmy Carter, and the Queen...all in their nineties...being in contact with so many people. That creepy Biden breathing all over the Carters, and the Queen’s nasty sons breathing on her...
God’s will, maybe??
Most colds are Rhino Virus, but a sizable percentage of what we call “Colds” are Corona Virus. (Technically, Common Human Corona Virus)

You are correct that Influenza Virus is not a Corona Virus.
Corona Virus is named for the “Crown” shape of an external structure that features little crown-like spikes.
There is no such crown on Influenza Virus.
Good grief...you must be a leftist.
Good to know.
I crushed it. All the hiking did the trick. My benchmark is the 680 foot / 1 mile climb to the Mary Daveys bench at the top of Rhus Ridge in LAH. Did it a couple days ago in 22:30.

Does your blood type affect your Covid-19 risk? It’s complicated.
After reviewing the medical records of 7,770 people who tested positive for the novel coronavirus, Nicholas Tatonetti, a data scientist at Columbia University, and graduate student Michael Zietz said they found that having blood Type A blood was associated with a lower risk of being placed on a ventilator, while having blood type AB was associated with a higher risk of needing ventilation, Zimmer reports. However, Tatonetti and Zietz cautioned that their results related to the AB blood type are less reliable than their results for other blood types, because there were few patients in the study with type AB blood.
Tatonetti and Zietz haven’t yet published the results from their full study, which is currently under review for possible publication in a scientific journal, Zimmer reports. The researchers have released preliminary results, which are based on a sample of 1,559, in a preprint study that hasn’t been peer-reviewed.
Separately, researchers at Massachusetts General Hospital (MGH) in a study published in Annals of Hematology, which has open access options, found that people with Type O blood appeared to have a slightly lower risk of contacting the new coronavirus, but they also found that a patient’s blood type was not associated with their risk of needing ventilation or dying because of Covid-19.
“If only we would study the ones who haven’t gotten sick, we might know more about how to treat the sick or prevent people from getting sick.”
Most docs probably feel more job satisfaction, when they cure a sick or injured individual, versus preventing a disease via vaccination, dietary changes and physical exercises.
