Right and if that is such a good thing why are those macrophages not always on alert. I smell longterm cancer or similar.

Or simply autoimmune reactions which can be devastating.

Indeed, I wonder whether the vaccine content matters at all in current vaccines. We could probably just inject people with the adjuvants and get the same result.

If only you had read the article.

there are many, many things our bodies could do (or not do) to greatly improve our health at no cost whatsoever.

That we think have no cost. The massive failure rate of drug trials and some famous cases of issues discovered only after wide scale deployment indicates we're not that great at knowing ahead of time.

The body is like legacy spaghetti code written by hundreds of teams of outsourced engineers. It mostly works. Just never remove any commented out lines or it may break.

While possible, there are also many bodily processes that are finely tuned through eons of evolution, and destabilizing pressure leads to disorder. Sometimes it's difficult to know which are which (or at least I don't know).

We shouldn't call it a vaccine when, in fact, it's just a line of cocaine for macrophages.

I'll be fascinated to see how this plays out for people with autoimmune conditions - generalised heightening of the immune system feels like it would be dangerous for those people. Are any immunologists lurking who might be able to speculate?

Its often completely normal to use healthy controls in a trial like this, healthy people not getting ill is your target audience and the long term stage 3 will be against healthy people. So many drugs are not tested against obvious groups that might produce a poor result to make the findings as strong as possible but it means in a lot of cases chronically ill people are making judgements on no data at all.

It seems like it could also be quite dangerous for those with food allergies.

why do they call it a vaccine, its nothing like that...

there's probably a reason evolution didnt put the immune system on permanent "amber alert" as they call it in the article

Are you wildly speculating or do you have a source with research backing up your claim evolution got it perfectly right?

I personally look forward to every innovation that potentially improves our baseline.

It would just be temporary, but there is likely trade offs.

True though there is the theory that it was unnecessary for the immune system to regulate itself in some ways because we were full of parasites.

One of the things I do worry about is glasses. Is there a reason why we correct vision? There's probably a reason evolution made some of us see the world in a blur. Likewise with therapy - maybe killing yourself is like cell apoptosis. Many body cells are supposed to choose to die when they no longer function well. It's a good thing. That's often the problem with scientists: "They were so preoccupied with whether they could, they didn't stop to think if they should".

Until we find out why nature made it so some of us kill ourselves maybe we shouldn't fuck with it? Remember Chesterton's Fence.

You're making the mistake of thinking of "nature" and "evolution" as intelligent, reasoning systems, and that every evolutionary adaptation exists for a purpose. Evolution doesn't do things for "reasons," things just happen.

Remember that cephalopod brains are donut shaped and their digestive tracts go right through the middle and if they eat something too big they'll have an anyeurism. Pandas and koalas evolved special diets that serve no evolutionary purpose and both would be extinct if humans didn't find them cute. Sloths have to climb down from trees to take a shit. Female hyenas give birth through a pseudopenis that often ruptures and kils them. Horses can't vomit and if they swallow something toxic, their stomach ruptures. Also their hooves and ankles are extremely weak and not well designed to support their weight. Numerous species like the fiddler crab and peacock have evolved sexual displays that are actively harmful to their survival.

And as for humans, our spines are not well adapted for walking upright, our retinas are wired backwards, and we still have a useless appendix and wisdom teeth. The recurrent laryngeal nerve has an unnecessarily long and complex route branching off the vagus and travelling around the aorta before running back up to the larynx.

Evolution is not smart. Evolution isn't even stupid. It isn't trying to keep you alive and it isn't even capable of caring if you die. Yes we should absolutely fuck with it, because we don't want to live in a world where we still die of sepsis and parasites and plagues because "we don't want to mess with evolution."

>koalas evolved special diets that serve no evolutionary purpose

Koalas biggest problem is us? Like they seem perfectly adapted to their niche. Eat lots of leaves that nobody else is adapted to use as food, and once a year, run very fast to outpace the bushfire that your principle food source needs to reproduce.

Yes, there’s a misconception that evolution leads to optimization and efficiency. It really just leads to traits that are “good enough”.
