New research using mice reveals that tattoo ink particles rapidly migrate into lymph nodes shortly after injection, where they remain detectable for extended periods. The study found that the pigments provoked immune cell death and sustained inflammation, while also impairing the body’s response to an mRNA-based COVID-19 vaccine. Scientists caution that the findings could have implications for long-term immune function in people with tattoos. The results highlight a potential link between tattoo pigments and altered immune behavior that warrants further investigation.
