It's nice to hear from our fellow recrepiants of the smallpox vaccine, but does anyone know anyone who actually performed the procedure? Several years ago P_RN stated in a post that she had administered many hundreds of smallpox vaccinations. In the post she indicated that the outcome of her incertions varied markedly from individual to individual. I would find it interesting to hear from someone like her if they have any knowledge why the size, placement, and even number of scars varies to such a large extent. One would think there would be a set standard.
