A disease, usually local and limited to the site of inoculation, induced in man by inoculation with the virus of cowpox ( vaccination). On about the third day after vaccination papules form at the site of inoculation which become transformed into umbilicated vesicles and later pustules; they then dry up and the scab falls off about the 21st day, leaving a pitted scar; in some cases there are more or less marked constitutional disturbances.
