RE:Photodynamic therapy combined with immunotherapy: Nov 15/23This to me, is the Holy Grail for Ruvidar. Long research paper but glanced through it.. Even standalone, the results have been great but when combined with an immunotherapy, should get amazing results.. The perception of lingering side effects needs to be overcome. Even vaccines are mentioned in this paper. But first, let's hope they get enough money to survive. Thanks for sharing.
