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 low-grade inflammation over time. Additionally, exposure to tattoo ink appeared to impair the body’s response to an mRNA-based COVID-19 vaccine, raising questions about potential long-term immune effects. Scientists caution that further investigation is needed to understand the broader implications for human health.
