From: Atlas of Clinical Medicine, Surgery, and Pathology, 1901, with caption: <i>Shows two boys, both aged 13 years. The one on the right was vaccinated in infancy, the other was not vaccinated. They were both infected from the same source on the same day. Note that while the one on the left is in the fully pustular stage, the one on the right has had only two spots, which have aborted and have already scabbed.</i>
