I hate to be that person, but cancer vaccines have existed for a couple of decades now (not to mention "cancer" is a whole list of different conditions that don't have a singular solution and will never have a single vaccine).
This might be the first of its kind, and it's still great news and I hope it passes trials, but I'm just so sick of these click-baity headlines.. (Also Tory-graph use a subscribe-wall, so even if you do click, you can't read what cancer it will be targeting)
(this is nothing against OP, just the article)
