If there is a history of canine exposure, the need for immunoglobulin after rabies vaccination needs to be determined by the level of canine exposure. Grade 1 exposures include contact with or feeding of an animal, licking of intact skin, and contact of intact skin with secretions or feces from a rabid animal or human rabies case. No medical disposal is necessary in this case and washing of the contact area is recommended. Grade 2 exposures include light bites on bare skin, minor scratches or abrasions without bleeding. This should be treated immediately and the wound vaccinated against rabies. Grade 3 exposures are single or multiple bites or scratches through the skin, licking of broken skin, contamination of mucous membranes with animal saliva, etc. Wounds should be treated immediately and require immediate rabies immunoglobulin and rabies vaccination. Level 2 exposures to the head and face where the animal causing the injury is not determined to be healthy are treated as Level 3 exposures.
