Jenner believed that both cowpox and smallpox were viruses that originated in the horse and passed to the cow,[134]:5253 and some doctors followed his reasoning by inoculating their patients directly with horsepox.

A Look at Each Vaccine: Smallpox Vaccine | Children's Hospital of [13], Modified vaccinia Ankara (MVA, German: Modifiziertes Vakziniavirus Ankara) is a replication-incompetent variant of vaccinia that was developed in West Germany through serial passage. The invention is directed to a poxvirus vaccine comprising a soluble truncated poxvirus envelope protein. [78] In 1768, Dr John Fewster reported that variolation induced no reaction in persons who had had cowpox. This represented "Target Zero", the objective of the campaign.

[15]:127376 These states report that their repositories are for possible anti-bioweaponry research and insurance if some obscure reservoir of natural smallpox is discovered in the future.

In 1959, the World Health Organization (WHO) launched a plan to eradicate the disease by conducting mass immunizations around the world. He recovered quickly.
