"Tattoos can cause lifelong changes to the body's immunity as well as affect vaccine responses, according to a new study. An international team of researchers has found that tattoo ink collects in the lymph nodes, affecting the body's resistance to disease, in findings published in the Proceedings of the National Academy of Sciences. While studies have previously investigated the toxicity of tattoo ink, scientists say this is the first time their effect on immune responses has been explored."
"Using tattoos on mice, researchers found that the animals demonstrated chronic inflammation in their lymph nodes that was acute and long-lasting, the death of macrophages (a type of white blood cell), and altered immune response to vaccinations. Tattoos could affect immune response and vaccine response (Getty/iStock) This work represents the most extensive study to date regarding the effect of tattoo ink on the immune response and raises serious health concerns associated with the tattooing practice, the team said, noting that at least one in five people have a tattoo globally."
An international team published findings in the Proceedings of the National Academy of Sciences showing tattoo ink accumulates in lymph nodes and alters immune function. Experiments in tattooed mice revealed acute and long-lasting chronic inflammation in lymph nodes, macrophage death, and altered responses to vaccinations. Previous research examined ink toxicity but did not assess immune-response effects. Pigment lodged in lymph nodes appears to influence the body's resistance to disease and vaccine effectiveness. The results raise serious public-health concerns, especially given that at least one in five people worldwide have tattoos.
