The end of Infectious Disease

I do think there is a lot of untapped potential for infectious diseases and immunotherapy research, and I think a lot of the missing impetus is a result of many of these disease not majorly impacting most well developed countries. However I don't know about this wide net you're casting with regards to curing cancer. There is certainly a role for immunotherapy in cancer treatments but we are talking about an extremely broad category. Often times the antigens expressed can vary from individual to individual even when talking about a specific cancer subtype, which can severely limit efficacy, and certain types of cancer occur in areas where an immune response can prove more fatal than the cancer itself. So yes there is a role, but cancer is such a broad entity that there is little accurate extrapolation that can be made when comparing effectiveness in treatments from one to the next.
