These vaccines for cancer survivors with a risk of recurrence aren't new. NWBO has had their GBM vaccine in trials for at least a decade and some day may even release results of their pivotal trial which underwent data lock in Aug 2020 I believe.

Talk about long-suffering investors, NWBO shareholders (I'm not one) were promised results in Sept 2020 and have been waiting since then with no significant update from the company (my guess is the results aren't good).
