This makes me both happy and sad to read. My mom was diagnosed with glioblastoma in 2013, and tried to enroll in a vaccine study but they didn't have enough material from the resectioned tunor to create the vaccine samples (or at least that's roughly what I remember the vaccine trial representative telling us). She died in 2018, which is more time than many glioblastoma patients get but I can't help but wonder if it would have been different if she'd been able to participate in the trial and had gotten the vaccine.
