Although he may have received some funding from some cancer research organizations, neither they nor the FDA was of much help. Industry translated the science into therapies, and I would not be surprised to find out that as soon as he made this remarkable discovery about the power of dendritic cells, that his funding dried up.
I have seen this with other diseases. Scientists are funded by the big organizations until they get close to making the breakthrough, and the grants get pulled or not renewed.
I don't think you can make an effective argument that the charities have moved the needle much in most of the serious diseases such as cancer, diabetes, or Alzheimer's.
