    1. Atrament z tatuażu trafia do węzłów chłonnych – i zostaje tam do końca życia. Co to robi z odpornością człowieka?

      Tattoo ink enters the lymph nodes, where it can remain for life and cause chronic inflammation.

      In mice, inflammatory markers were 5 times higher even 2 months after tattooing, and their bodies' response was weaker to mRNA vaccines and stronger to protein vaccines (e.g., influenza).

      Macrophages overloaded with ink absorb fewer vaccine components. Studies of human lymph nodes have confirmed that pigment remains in them long after tattooing. Chronic inflammation can weaken the immune system, increasing the risk of infection and cancer.

      In Europe, more than 60 million people have tattoos, and the ink may contain high levels of heavy metals that exceed acceptable standards.
