Vector graphics *describe* shapes rather than store pixel data. To display a vector image, the rendering engine has to interpret the vector shape data and convert it to a raster (pixelated) image at whatever pixel resolution is desired. So zooming a vector graphic results in it being re-rasterized at higher resolution, and since the original data describes the shapes independently of any fixed resolution, you can do so with no quality loss
