No, we’re not talking about Twitter bullying, we’re talking about shots. Not cheap shots, or gun shots, but vaccine shots. Two studies published in Nature detail how DNA sequenced from melanoma tumors (the most deadly type of skin cancer) and an RNA-based vaccine were used to create personalized vaccines to treat cancer. Both showed promising Phase I results, with 4 of 6 patients in the first study showing no recurrence after 25 months, and 8 of 13 patients in the second study tumor-free after 23 months. The vaccines successfully stimulated an anti-tumor response from one’s own immune system. The downside? It took about four months between study admission and starting treatment, which may be too long for those with advanced stages of melanoma.
