What happens if a domestic animal currently vaccinated against rabies is exposed to a rabid animal?

When a domestic animal that is currently vaccinated against rabies comes into contact with a rabid animal, it is crucial to act swiftly to ensure the continued safety of both the animal and public health. The correct response requires administering a booster vaccination to the exposed animal because the presence of the rabid animal poses a significant risk, even if the domestic animal is vaccinated. This booster helps to enhance the animal's immune response to the rabies virus.

Additionally, confinement of the animal is necessary. This allows for observation over a specific period to monitor for any signs of rabies, ensuring that the animal does not develop the disease and pose a risk to people or other animals. This protocol is important to maintain the health and safety of both the animal and the surrounding community.

The other choices do not adequately address the potential risks associated with rabies exposure, making the selected response the most appropriate course of action in this situation.
