I know two or three Parvo survivors (rescue dogs) and they've all gone on to live normal lives. Can't speak for the individual pup in this case but there haven't been any implications to their long-term health or the ability to insure them. Some insurance underwriters are more generous than others though so you may need to shop around.
Just beware the 'second puppyhood' depending on how old the pup is! The quiet little poppet in recovery can start to make up for lost time once they're fully better and settled.
