This isn't a preventative vaccine like that. It's something that has to be developed after you have cancer to target your tumor's specific mutational profile. So mass production (just churning out the same thing in bulk) isn't really an option! Costs will probably come down eventually, but it's going to take research, technology development, and hard work to make that happen.

Is it possible that there is only a relative handful of these profiles and we can have these vaccines already on hand for each of them?
