Several things are of interest in this graph. First, despite the fact that the smallpox vaccine was introduced in 1798 and very strict vaccination laws were enacted in England, smallpox epidemics still raged on until the 1880s when all diseases began their decline. Second, there is a very similar pattern of epidemics with scarlet fever and smallpox, which suggests a possible relationship between the two diseases. George Washington vaccinated his troops. It was done with pus from humans, not from cows, which came later. |

Vaccination (from the Latin) for cow is inoculating with cowpox to prevent smallpox. |

Vaccination (from the Latin) for cow is inoculating with cowpox to prevent smallpox. I also posted the book Pox Americana which described the effect of smallpox on early America and included a good discussion of variolation. But it had the same effect as the later cow pox materials...it prevented death. |

Jenner thought he was using cowpox. However, it's a great mystery just what the Vaccinia virus is. It could be a modified smallpox virus, a modified cowpox virus, a smallpox-cowpox hybrid, or a virus distinct from both smallpox and cowpox. Nobody knows where it came from. There may be a natural host harboring the Vaccinia virus, but none has yet been discovered. |

It's regular smallpox, and some inoculations would progress to the full-blown disease. The advantage of inoculation is that the infection site is on the skin instead of in the lungs, which greatly reduces the chance that the full-blown disease will develop. |

I think the camelpox virus is most closely related to vaccinia. http://www.cidrap.umn.edu/cidrap/con.../camelpox.html |

With variolation they tried to use someone who had been infected "naturally," and then on to a second generation, and finally the third generation was best used. The problem was that the vaccinated were highly contagious so city officials were reluctant to do variolation because it would spread the disease unless those "variolated" were kept in isolation. |
