One: the point. Vertices are points. And it has one edge, which is circular.
The description given fits that of cones
Pyramids end in one vertex and prisms end in multiple vertices. E.g. Rectangular Prisms are like cubes( multiple vertices) and pyramids are like cones (one vertex).

A pentacontagon has 50 vertices (not vertices's!).
A "dose" is a measured portion of a medicine. I am not aware of any cones that have measured quantities of medication! A finite cone has one edge and one vertex.
