I’m not sure exactly how this should be classed. According to the article it deactivates part of the cancer cells which then allows the patients own immune system to attack and destroy them.

So it isn’t really a treatment as it doesn’t destroy the cancer itself. The patient’s own immune system does that.

However a vaccine technically works by providing the immune system with the “blueprint” of the disease so the immune system knows how to destroy it if infected. Which isn’t what this is doing.

I suspect it probably has a long scientific name that average people won’t understand and makes for a crap headline.
