That may well be the more correct term, I’m not in a medical profession, just read some articles about it (and news are usually not great about terminology). But as someone in another thread wrote, they’re calling this one a “neoantigen therapy” to avoid triggering RFK 🙄

Many of the new mRNA vaccines, especially those against cancer, aren’t usable that way anyways, e.g. from the article:

individually tailored to target a patient’s unique cancer mutations

So you get those, when you already have the disease, the reason it’s called a vaccine is because it’s making your immune system fight it instead of directly acting on the cause
