New research involving mice reveals that tattoo ink particles rapidly migrate into lymph nodes shortly after application, where they remain detectable for extended periods. The study found that the pigments provoke immune-cell death and sustain chronic inflammation, potentially impairing the body’s ability to mount an effective response to vaccines like mRNA-based COVID shots. Scientists warn the findings could have broader implications for long-term immune function in tattooed individuals. The results highlight a previously understudied biological interaction between cosmetic pigments and the immune system.
