Antimicrobial agents like silver nanoparticles or zinc oxide are sometimes used in paints applied to skin to help prevent infection. These elements have properties that inhibit the growth of bacteria and other pathogens, reducing the risk of infections when the skin is painted.
Iodine is used on wounds as an antiseptic agent to prevent infection. It has broad-spectrum antimicrobial properties that help to kill bacteria and other pathogens on the skin's surface. This reduces the risk of developing an infection in the wound.
Basically, neither. immunisation prepares the body for the possibility of that infection, and increases the ability of the body to fight it off. It is not a cure, because a cure is applied after the fact and directly acts against the infection; it is not a prevention, because the disease will still happen anyway.
