Can’t bring myself to be surprised about this

Perhaps the medically knowledgeable would care to comment on this:

People who have previously had Covid or been vaccinated have T-cells in their system that work well against omicron, a new study suggests.

T-cells are a form of immunity that are longer-lasting than antibodies, and although they do not stop infection, they prevent the virus from causing severe disease and death.

This seems so obvious to me as to not be worth wasting the pixels upon. True, this is probably because once we get to the nitty gritty I know nothing about biology. So, those who actually do know. This is so obvious? Or, actually, no, it’s really new news?

  1. The immune system isn’t just antibodies, you know 🙂

    AIDS actually targets T cells, which is why it’s so nasty. Looking at London’s previous high resistance to the Delta wave, despite it’s low vaccination rate, which then collapsed somewhat when Omicron arrived, I suspect both vaccination and natural immunity are less useful against the latter: London was hit hard earlier on

  2. T cells — immune “memory” — are the long term parts of the system. They can also provide quite wide-ranging immunity by recognizing different parts of a pathogen. One thing that got lost from sight in the spring of 2020 was that 80% of the passengers on the Diamond Princess cruise liner (which was being quarantined for the original SARS-COV-2) showed no sign of infection, even if sharing a cabin with the seriously ill — a case of “that’s a coronavirus, I’ve seen those before”. On the down-side it does make T-cell mediated auto-immune diseases intractable — things like MS, which is looking ever more likely to be a response that recognizes a myelin-like part of the Epstein-Barr virus.

  3. It is….cringy… but essentially correct.

    And more of a scientific confirmation of what was expected to happen anyway, and any monitoring station has confirmed so far. But Science Needs Publication Confirmation.

    Of course, this being biology, they’ll soon find the 1:100.000 odd exception, and that will be plastered all over the front pages, and every hypochondriac will insist …etc..

  4. We’ve been fighting bugs ever since we were bugs ourselves. And we have allies in the vast number of symbiotes on our skin, in our blood and guts. That makes at least five layers of resistance.

    Often people die of the side effects, not the disease. Cholera isn’t a killer, it’s dehydration that kills. That was why I was so baffled that the medics wouldn’t try anything new to treat covid, instead using ventilators inappropriately.

  5. I wish one of those press conference journalists had asked Whitty/Vallance/Johnson what’s the best way for an older person to maintain a healthy thymus gland.

    I think Whitty would have understood the question. Vallance, I doubt it. Johnson would have cracked a grin.

  6. This is, like a lot of scientific research, confirming that the things we already knew still apply to the latest variation.

    One time in a million or whatever, you do confirmatory research and you go “oh, it doesn’t work in this case” – and that’s when you get a huge breakthrough (to take an example from physics, which I know better than biology, the Michaelson-Morley Experiment was intended to measure the proper motion of the Earth against the universal framework and ended up discovering that there isn’t a universal framework and so led to the discovery of Relativity).

    To quote the Royal Society’s motto: “Nullius in verba”.

  7. The Diamond Princess, that plague ship trapped off Japan in February 2020, was a perfect natural experiment although heavily tilted towards the wealthy aged and infirm: everybody exposed via aircon, only 17% tested positive, half of whom remained symptomatic, seven deaths all over seventy with comorbidities: natural preexisting immunity at work. Utterly ignored by public health “experts”

  8. Isn’t it the case that certain vitamins are important for keeping your immune system in good nick? It seems odd that there has been no information put out about which vitamins and supplements would be likely to help.

  9. Somebody was speculating recently that the AZ jab will do a better long term job than the mRNA jabs because it somehow gees-up the T-cells more effectively. (Forgive the technical jargon.)

    @Stonyground: we’ve been taking Vitamin D and Zinc since early Feb 2020. Hasn’t everyone?

    @Ljh: I agree entirely. It was the Diamond Princess data (late Feb 2020) that let me breathe a sigh of relief and claim that Covid was not a big deal.

    I called it a “natural experiment” on a blog comment thread and someone protested that it wasn’t a proper experiment because it wasn’t a Randomised Controlled Trial. ‘For ye have the stupid with you always’ said Jesus, nearly.

    Do a search on Jo Nova’s and Small Dead Animals’ websites. They have numerous items with links to vitamins and antivirals that assist against the Covid bullet.

  11. . . . we’ve been taking Vitamin D . . .

    Are you also on vit K2 (mk7)? Something to do with it preventing calcium buildup in the arteries that happens with high level D3 supplements.

  12. No, its ‘pretty obvious’. The point of a vaccine is to prime the immune system to produce anti-bodies quickly the next time the threat is detected after all.

    And unless the virus mutates sufficiently enough that its not recognized by the immune system anymore – then of course protection from one variant will pass over in some proportion to another.

  13. The Diamond Princess is the key to everything. All other data are superfluous.

    Wikipedia: Of the 3,711 people on board, 712 became infected with the virus – 567 of 2,666 passengers, and 145 of 1,045 crew. As many as 14 are reported to have died from the virus, all of them older passengers.

    At which point it was already obvious that the extent to which this was a ‘novel’ coronavirus was highly dubious. But then, there’s little academic glory in discovering a virus that isn’t particularly novel.

  14. I was leaning towards the lab leak theory early on based on the way the authorities reacted to it and kept insisting you couldn’t assume it would act like a normal coronavirus, that they knew it was artificial and worried about it not acting ‘normally’

  15. @PJF: I have good reason to shun Vitamin K. I do wish that quacks, sorry GPs, were more rational and better informed about supplements so that they could give advice worth listening to.

  16. “Wikipedia: Of the 3,711 people on board, 712 became infected with the virus – 567 of 2,666 passengers, and 145 of 1,045 crew. As many as 14 are reported to have died from the virus, all of them older passengers.”

    Back of a fag packet calculation: (14/2666)*25m (there are 25m people in the UK aged 50 and over, I’m guessing almost all the cruise ship passengers would have been 50+) = 131k deaths. Chuck in a few deaths among the under 50s (who in the UK will be a lot fatter and less healthy than the young Filipino crew on a cruise ship) and you’re pretty much where we are at deaths-wise.

    Can I get my job at Imperial College now?

    K or K2, re coagulation and all that? I thought K2 was different wrt that. Am I wrong?

    Bongo

    LOL

    Ljh/DM/Paul

    Princess – quite. Paul, I wouldn’t go so far as superfluous, but much of what followed has happily riffed off that information (along with the earlier/first off data from China on age stratification).
