What should you know about a rabies booster after a dog contact?

A booster is an additional vaccine dose used when a person has already completed a rabies vaccination course and has a new exposure or a recognised ongoing risk. It is different from deciding whether someone needs a first course of post-exposure treatment. A clinician considers whether teeth or claws broke skin, whether saliva reached a vulnerable area, and whether the dog can be safely observed or assessed.

Wash any bite or scratch immediately with soap and running water. Avoid touching the wound with unwashed hands and do not delay care while searching for vaccination records. Record the dog’s owner details if safely available, ask whether its rabies vaccination is current, and report the exposure through the appropriate local health or animal-control service. Do not approach a loose or behaving-unusually dog.

Arrange urgent medical assessment after a bite, scratch, or saliva contact with broken skin, even if the dog appears well. Go immediately for a wound on the face, head, neck, or hand, an injury in a child, deep tissue damage, or bleeding that does not stop with firm pressure. A clinician can decide whether a booster, other post-exposure treatment, tetanus care, or wound treatment is appropriate.

Ask whether your earlier rabies vaccines change the recommended treatment, whether the dog should be observed, and how quickly each dose should be given. Share your vaccine dates if known, the time of contact, the wound location, and any information about the dog’s health or vaccination.
