Abstract
The durability of immune responses to smallpox vaccine is a subject of considerable debate. We compared cutaneous vaccinia responses in patients vaccinated in the distant past with vaccine-naïve individuals using serial close-up photographs. The previously vaccinated group had a significantly reduced time course and milder cutaneous reactions. Vaccinated individuals appear to maintain clinically detectable immunity against vaccinia for at least 20 years after smallpox vaccination.
