I wouldn’t call this a vaccine per se, but it’s definitely very good news. From what I recall this is especially effective against glioblastoma’s which seem to be the majority of brain cancers. They’re also one of the nastier forms of cancer of the brain because there’s no known cure, only palliative measures.
I lost a good friend to that disease. I wish he was still alive to benefit from this.
Little by little we’re beginning to conquer diseases which for years eluded any curative measures. This is good news. It means human lifespans will now extend a bit more.
