I'm not sure what your point is. I know how vaccines work. Just because you don't seem to understand how this one works, does not mean that I have any need for your attempt to make it sound like you know more still. It isn't the virus. They make VLPs (virus-like particles), and in this case, they make them from the capsid protein, not even the virus itself. That would be like saying "Lactose comes from milk, therefore, it is milk". It's not the same at all. In this case, they have taken a protein derived from the capsid that tends to self-assemble into similar structures as the virus itself does. It still isn't the HPV virus.
