New research involving mice reveals that tattoo ink particles rapidly migrate into lymph nodes within minutes of application and remain detectable for months afterward. The study found that the pigments triggered the death of immune cells, led to chronic inflammation, and may impair the body’s response to an mRNA-based COVID-19 vaccine. Scientists warn these findings could have broader implications for immune system function and vaccine efficacy in people with tattoos. The results highlight unexpected biological interactions between tattoo pigments and the immune response.
