Was Edward Jenner actually the first to come up with cowpox preventing smallpox?

Probably not. He was the first to conduct trials on multiple people and bring his results to a large and legit medical society. There was a person at least 20 years before Jenner’s discovery who infected his family to cowpox, but none of them were infected.
