I would say the answer to your question is impossible. The first human to get smallpox discovered it. But, the vaccine is another story all together~Edward Jenner, M.D., LL.D., F.R.S.
While still an apothecary's apprentice in the late 1760s, Jenner had been intrigued by possible relationships between smallpox, cowpox, and swinepox. At the time, he was ridiculed. By 1780, however, he returned to the idea, as evidenced in the conversation recorded here, and in 1789 he experimented by inoculating his own son, then aged one-and-a-half, with the swine pox, followed by conventional smallpox inoculation.

No one discovered smallpox. Edward Jenner discovered the vaccine for smallpox in a hospital in London that is still there today.

the Indians. It became contagious when the Europeans came into America. They had it on the way over here, didn't know it, and got it over everything that they had. So when they made it to shore, and gave their belongings as gifts to the Indians, who had no idea of what was going on, the caught it and died. Then it began to spread.
