Definition of Autoinnoculation

Autoinnoculation: Inoculation of a microorganism obtained by contact with a lesion on one's own body, producing a secondary infection. This can happen, for example, with a fresh smallpox vaccination if the person who has been vaccinated touches it and transfers the virus to a scrape on their body.
