A tattoo can be more than just a fashion statement – it has potential medical value, according to an article published in the online open access journal, Genetic Vaccines and Therapy. Martin Müller and his team at the Deutsches Krebsforschungszentrum (German Cancer Research Center), Heidelberg, Germany, have shown that tattooing is a more effective way of delivering DNA vaccines than intramuscular injection. Using a coat protein from the human papillomavirus (HPV, the cause of cervical cancer) as a model DNA vaccine antigen, they compared delivery by tattooing the skin of mice with standard intramuscular injection with, and without, the molecular adjuvants that are often given to boost immune response.
