Profile of vaccine technologies used in vaccine trials. (a) Bar graph of total number of cancer vaccine trials conducted for each vaccine platform. The bar height and the number on top of the graph represent trial count, though single vaccine trials may at times incorporate multiple vaccine platforms; (b) Vaccine platforms for Dana-Farber Cancer Institute vaccine trials; (c) Vaccine platforms for Memorial Sloan-Kettering Cancer Center. The color coding is the same as used in Fig 1. When the vaccine technology is not known for the trial, it is labeled as "Empty".
