Why do some people never get COVID while others get it several times, even if vaccinated?
San Francisco Chronicle ^ | 04/25/2022 | Danielle Echeverria

There are many people who have never gotten COVID-19, despite repeated exposure. At the other extreme, there are lots who’ve gotten sick from the coronavirus more than once, despite being vaccinated and even boosted.

Do we know why?

A lot of factors are at play, experts said, including genetics and variations in immune response. Scientists are working towards finding a clear answer.

Are some people genetically immune to COVID?

There’s a difference between people who can never catch COVID, despite exposure, and those who are able to clear it out of their systems without ever knowing they had it. If this second category of people tested regularly, they might show positive for a day or two. Different factors are likely at play between the two groups.

"It’s so messy,” Dr. Julie Parsonnet, an infectious disease specialist at Stanford University. “We don’t know how to differentiate between whether you’re just lucky, really careful or if genetically something is different.”

In one study, conducted in early 2021 and known as the human challenge study, 36 healthy young adult volunteers — none of whom had been vaccinated or previously infected — were deliberately given the virus that causes COVID-19 in their noses and tested frequently afterward to track infection. Remarkably, nearly half never got infected at all.

I’m an old broad, work in a nursing home, have been exposed a million times, have never been vaccinated, and have never had Covid. I had a co-worker older than I, healthier than I, unvaccinated but came down with Covid and died. Oy.

I am currently down with a head cold, I don’t expect COVID, despite being on a year-plus regimen including 6000 IU of vitamin D. I have had other lesser illnesses I have shaken off, and thought my new look at vitamins was helping me.

It may be, as I am recovering in about 4-5 days, but I had a fever for a day, despite the vitamins.

I would like to think that vitamin D was a silver bullet, but I also now know that it won’t prevent viral infection. Perhaps it is substantially aiding recovery, but that can’t be proven by just my case.

COVID should act like any other cold virus, I would think.

So, all these years and the author never figured out why some get the flu or a cold while others did not?

Everyone has a credit score. What everyone needs also is a health score. Then we could say that everyone with a health score of say 750 would not really have to worry about getting the virus: they would either be asymptomatic or else have a mild case. However those with scores below 500 or so should isolate and wear masks.

Well, it isn’t really hard to explain. They are the people who run to get “tested” every time they sneeze, or even when they have no symptoms at all, with a test that the CDC admits generates false positives ~94% of the time.

Stop “testing” everyone, and “COVID” would disappear entirely.

EVERYTHING about “COVID” is a LIE.

“For those noobs who haven’t yet built a robust, post-apocalyptic skill set, we need to bring them into the fold. Liberty grows when the field of participants expands, not by shrinking ourselves to glory.”

Doing my best on the Garden Thread each week. We touch on skills needed for success all the time!

Came across this quote, recently. I find it inspiring. No WAY will Mother Government defeat me:

“We should never despair, our Situation before has been unpromising and has changed for the better, so I trust, it will again. If new difficulties arise, we must only put forth New Exertions and proportion our Efforts to the exigency* of the times.” ~ George Washington, President

*This word sums up our current plight, perfectly. More people should use it. :)

They fail to mention vitamin D levels. I would bet it the single most obvious variable.

I've been taking Vitamin D supplements daily for the past 20 years of my life, well before this pandemic nonsense ever started. I also eat well and spend plenty of time outdoors (with no sun screen).

I suspect that this is why I have never come down with the COVID, despite taking no precautions, not being "vaccinated", not masking up unless it is absolutely mandatory (like at a hospital) and not worrying at all about social distancing. During the past two years I've ridden public transportation, attended Trump rallies, worked in NYC.

For some reason, everybody wants to pooh-pooh Vitamin D. So far, I am not personally aware of anybody getting the COVID who had proper Vitamin D levels. If I ask somebody who did get it about Vitamin D, I never get a straight answer. They are quick to dismiss that it is even a relevant question. Many think it is conspiracy stuff to tie lack of Vitamin D to COVID.

Strange.

IF this is a lab created bioweapon (I think it is) then knowing if some people are genetically immune would be VERY valuable knowledge for refining the weapon. You could refine it so as to protect your own racially similar population while eliminating others. It is a good thing that our CDC didn't send 10% of all the nasal swabs that were collected for testing to the Communist Chinese to gather positive or negative results from along with accompanying DNA samples and...hey, wait a second.

I’ve never been vaxed, never gotten covid, been in the hospital twice during pandemic (major surgery both times.) My wife’s brother and his wife, twice vaxed and they both have had the ‘rona at least twice since being vaxed. I think this “rushed” vaccine is part of the issue and I keep coming around to thinking that this whole freakin pandemic was planned and orchestrated in order to distrupt the world economy and help install the NWO...

“...do you know if D3 is as effective? Or is it the same thing?”

Talking about the vitamin D your body makes. Never hear about the very common low levels in people. Why, because there are easy, non profitable ways to boost it. Namely get some sunlight and proper diet. Instead we hear; “stay in your home”, “the sun causes skin cancer” and “milk and eggs have cholesterol”.

You forgot to mention how much dirt you ingest as a kid.

I personally think that kids grow a healthier immune system if allowed to play outside of a “sterile bubble”. As a kid, not washing your hands to eat (as mom instructed), not cleaning well behind your ears, walking barefoot in the mud, making mudballs, digging holes in the ground barehanded...all adds some unquantifiable, boosting element to your resistance. Moms that kept their kids fresh-off-the-shelf sparkly clean and sanitized were doing them no favors.

biden proved the kung flu is a scam when he waltzed into the white house, disbanded trump’s “operation warp speed”, opened our southern border, and is still covertly spreading over 2,000,000 nondocumented unvaccinated invaders across our country during a supposed “global pandemic” while anthony fauci, the cdc, the nih, the world health organization, the enemedia, hollywierd, and the majority of our elected representatives sit back and watch...

It’s called getting enough Vitamins B6, C, D3, E and K plus supplemental zinc. And not smoking. And also within reasonable body weight.

Fixed it” to something really ridiculous and factually false, yes.

Why do you guys persist with your frauds ?

Every comment, opinion and belief is as flaming liberal prog as it gets.

You and your ilk fool no one.

Either you all are psycho, pathological liars, zealots or paid.

I grew up as a kid in San Jose, so we would be outside year round.
I would play with bugs, pet strange dogs, then pull a tangerine off of our tree and eat it.

Work in a small rural Hosp. now and again.....

I've been up in the grills of many people that have the COVID...I've done CPR on a few of them too...

Never got the shot / shots.

The Fed's have lied to the citizens of this country...Period.

Why are so many people that are "fully" Vaxed getting the COVID and dying?
