Similarly, human immune cells previously exposed to ink also showed a weakened response to vaccination.

Ah pretty interesting. Good to clarify that its in mice, not humans.

“Human immune cells”, not cells in humans.
That’s not to say this doesn’t happen in humans, it very well may. It’s intriguing research, but it’s still only demonstrated in mice. Important to always keep that in mind until we get better information (which this research is at least leading us to).
Lots of stuff happens in mice (or pigs) and we find doesn’t replicate to homo sapiens.

It’s also important to keep on mind that the burden of proof is on something to prove or is safe, not that something is unsafe. It happening to human cells in mice would have me assume it happens to human cells in humans until proven otherwise (that’s the null hypothesis in this situation). But also I don’t have a tattoo or any interest in getting one so I’m not too bothered by this.

Humans have been tattooing each other for over 5000 years. I would argue that it’s not really a case of “they need to be proven to be safe”. That ship has sailed. If they are unsafe, we should know, but I think the burden of proof has definitely shifted on tattoos given their extensive history without obvious negative repercussion

I suspect the effect might be less significant in humans (not human cells, whole humans) because of the square-cube law.
