Great news.
Is it a new technique?
I have heard they tested it and it prevents viral infection. But have they proven it prevents cancer? Looking at it another unlikely way, what if it isn't the virus that causes the cancer but the immune response that causes it? The vaccine itself could create more cases of cancer. I know that seems absurd, but it seems like they really don't know what causes any kind of cancer. It seems a good case to sell a lot of new drugs though.
