Nowadays tattoos are common with 29 percent of Americans having at least one on their body.

The American Journal of Human Biology has found that those with more than one tattoo have a higher immune system than those without more than one. They found this out by collecting saliva from 29 subjects (5 men and 24 women) before and after they were tattooed. What they found was that the immunoglobulin A in the subjects with previous tattoos would be affected less than those without one previously.
Drawbacks to this study are that it is not yet conclusive and only had 29 subjects in the tests.
