The following submission statement was provided by /u/AdmiralKurita:

Article states that the vaccine may be available in ten years or so. A potential use for these vaccines is to vaccinate those with a predisposition for cancer, such as those with BRCA1 or BRCA2 mutations or those who had cancer and are at risk for re-occurrence, as oppose who have advanced cancer.

Oddly enough, the article agrees with my negative assessment on the progress of oncology over the last few decades:

>A breakthrough like that can’t come soon enough, say breast cancer
advocates. “I was diagnosed in 1987, and I wasn’t treated much
differently from what is available today, in terms of surgery and
chemotherapy,” says Fran Visco, president of the National Breast Cancer
Coalition, an advocacy organization. “Yes, there is a lot of focus on
immunotherapy, and that’s exciting from a research perspective. But it
hasn’t really made a difference in women’s lives yet.”

There are a few more targeted therapies.
