The researchers discovered that once a tattoo is made, the ink rapidly travels through the lymphatic system and, within hours, accumulates in large quantities in the lymph nodes — key organs of the body’s defense system. Inside these nodes, immune cells called macrophages actively capture all types of pigment. This ink uptake triggers an inflammatory response with two phases: an acute phase lasting about two days after tattooing, followed by a chronic phase that can persist for years. The chronic phase is particularly concerning because it weakens the immune system, potentially increasing the susceptibility to infections and cancer. The study also showed that macrophages cannot break down the ink like they would other pathogens, wich causes them to die, especially with red and black inks, suggesting these colors may be more toxic. As a result, ink remains trapped in the lymph nodes in a continuous cycle of capture and cell death, gradually affecting the immune system’s defensive capacity.
The study found that tattooed mice produced significantly lower levels of antibodies after vaccination. This effect is likely due to the impaired function of immune cells that remain associated with tattoo ink for long periods. Similarly, human immune cells previously exposed to ink also showed a weakened response to vaccination.
There are far too many humans with tattoos that could have been researched extensively, but they chose mice. Mice do not have the same kind of skin density as humans, and I doubt a tattoo artist or researcher would have the talent to tattoo a mouse’s skin.
There’s just so many things wrong with using mice in this study. So many bad ratios with the size of the animal. I mean, for fuck’s sake, tattoo artists already practice on pig skin. Pigs would have been a better analogue, but honestly, they should have picked the millions of humans who were already tattooing themselves.
Of course, if they did that, they wouldn’t get the same result and be able to push this sensationalist science news title, now would they? Except, in this case, we’ve gone from research paper to straight to sensationalist news title in one step! Just let the institute PR department push the narrative for you, without having to wait for that pesky news cycle to crawl through the telephone game.

Within a single city, hundreds of people get tattoos each day. A large cross-section of those probably haven’t refreshed their COVID vaccine, but only because they haven’t gotten around to it.
Just use pigs.
Basically the same thing as a human (except for the opposable thumbs, which explains us eating them), but cleaner and smarter on average.
Why not be a professional scientist by:
- adding “in mice” to the title;
- using modern statistical methods instead of continuously discredited procedures like p-values?
- adding “in mice” to the title;
Similarly, human immune cells previously exposed to ink also showed a weakened response to vaccination.
In a Petri dish!
The anti tatto crowd licking their lips over this one.
@Wubwub anti tattoo crowd? Like fundamentalist Baptists?
I suppose I would be in that crowd. I’m an atheist, but I think the whole tattooing thing is kinda stupid. To each their own of course, I don’t care if anyone gets a tattoo, but the culture around it annoys me and I think it’s a waste of one’s body. I do like some of the art styles, but why not just print it on a shirt and wear it?
That being said, I think it’s petty bad if it turns out the ink causes a higher risk of disease. Like with cigarettes in the past people weren’t informed about the consequences before making their choices. That sucks and I don’t wish it on anyone.
It’s good that you’ve expressed misconception as the source of this opinion, and admitted to your lack of understanding. The rest of the work could fall in nicely, if you put the effort forth. I’ll give ya one for free: “the culture around it” isn’t some singular entity, but a varied and colorful amalgam of countless inspirations, backgrounds, beliefs, reasons, etc., and the only thing that oversimplifying does here is stunt your personal growth.
You got this. 🤘🏼
Thanks, I’m good.
Hardly. 🤷🏼♂️ Not my monkey, not my circus. Good luck.
Like with cigarettes in the past people weren’t informed about the consequences before making their choices.
Yeah, but the tobacco cartels had performed studies which clearly demonstrated how absolutely horrible their shit was and not only not made them public, but used them to maximise addiction (and cancer, as a side effect they didn’t give a single shit about).
I very much doubt the tattoo industry has ever studied anything.
Oh definitely, the tobacco industry is way worse. Tattoo artists (at least in my county) have to follow hygiene regulations and aren’t allowed to tattoo minors, and there don’t seem to be any issues with this. There isn’t any incentive for them to cause harm to their customers, on the contrary, so I don’t blame them for this. If tattooing poses serious health risks like this study suggests, it would suck for everyone involved.
I’m a pantheist and think that tattoos are just another form of self harm
My gf has tattoos and I don’t mind them but I wish she wouldn’t get any more. Impossible to find a girl without tattoos who would date me anyway lol I tend to attract the alternative crowd and basically everyone I’d be into has them so it is what it is
Ah pretty interesting. Good to clarify that its in mice, not humans.
Well, then. That could explain a lot about why I always feel like I’m dying.
I have the opposite problem, my immune system is in overdrive. I should get a tattoo to reign it in.
i feel like that would cause an immediate inflammation, if your immune system is dysregulated, it would have a likely opposite effect of what it suppose to do. ive seen alot of people in tattoo sub said they had a reaction to the tattoo after its done.
thats why some people get a rash at the tattoo sites, or it triggers shingles. make sense since macrophages clean up melanin pigment produced by post-inflammatory hyperpigmentation, a brown spot after a severe pimple or something.
in mice.
What is your opinion on how much this applies to humans?
Steve-O is still alive; humanity will be fine.
