Did vaccinia virus come from a horse?

Until about 70 years ago, it had been generally accepted that the virus of smallpox vaccine was the same as that which caused cowpox in cows.
This view, however, could not be confirmed or challenged before some means of propagating viruses in the laboratory had been devised.
