Final answer:
Animals are typically vaccinated for rabies at three months of age with booster shots every one to three years. Rabies vaccination is crucial for preventing the spread of the virus. The spread is also controlled by oral vaccines in wild animals.
Step-by-step explanation:
The question asked about the age by which all animals should be vaccinated for rabies, and the period thereafter. Rabies vaccination is essential in controlling the spread of this deadly virus. Rabies immunoglobulin is given near the site of the bite to inactivate any rabies virus present in the tissues, and this is followed by a series of vaccinations over the next 14 days to develop active immunity. Rabies is caused by the rabies virus, a bullet-shaped RNA virus from the Rhabdoviridae family, and Louis Pasteur developed the first rabies vaccine from dried nerve tissues of infected animals. In the United States, the widespread vaccination of dogs and cats has resulted in a low incidence of rabies, and an oral vaccine is used for wild animals in rabies-endemic areas.
Rabies vaccination for animals is typically initiated when they reach three months of age, with booster shots given at regular intervals thereafter, typically every one to three years, depending on local regulations and the type of vaccine used.
