Covid appeared during winter 20-21. A usual common cold and flu season. That was not quite a success to fight it. Fake news?
daughter is in a long term virus monitoring study for past 7 years and had a “cold” in November we sent a swab which showed [HCov-C43](https://en.wikipedia.org/wiki/Human_coronavirus_OC43) AND an at the time unclassified Adenovirus variant.
>Coronaviruses have a worldwide distribution, causing 10–15% of common cold cases (the virus most commonly implicated in the common cold is a rhinovirus, found in 30–50% of cases).
My guess is anyone that has have any of those cases in the 10-15% will have some immunity
We knew this year’s ago. But under the media cabal commitment to not undermine health advice it wasn’t allowed to be promoted for fear people get uppity
> We detected spike-reactive CD4+ T cells not only in 83% of patients with COVID-19 but also in 35% of healthy donors. Spike-reactive CD4+ T cells in healthy donors were primarily active against C-terminal epitopes in the spike protein, which show a higher homology to spike glycoproteins of human endemic coronaviruses, compared with N-terminal epitopes.

I’m a little puzzled by this paper.
If they’d claimed that cross-reactive T-cells gave an immune benefit to people with a prior cold infection, I could get on board, but they’re trying to claim that Cross-Reactive MEMORY T-Cells are somehow *preventing* a covid infection from occurring!
While antibodies can shield a body from infection, but operating within exposed tissues and destroying antigens before they even start reproducing, Memory T-Cells are only engaged *AFTER* an infection has commenced.
While clearly there is a correlation observed here, I find the proposed headline conclusion unwarranted.
Correct me if I’m wrong but wasn’t one of the reasons the Oxford team came up with a vaccine so fast is that they were working on a vaccine for common cold coronaviruses? In which case it’s not too surprising that if you’ve had the right common cold then you might have some protection against covid.
That might explain why I’ve been exposed twice and never caught it.
Despite being indoors talking to infected people, with symptoms, in close proximity, for long periods.
I have had every fucking cold known to human civilisation though.
