Before exposure The World Health Organization (WHO) recommends vaccinating those who are at high risk of the disease, such as children who live in areas where it is common. Other groups may include veterinarians, researchers, or people planning to travel to regions where<unk>  is common. Three doses of the vaccine are given over a one-month period on days zero, seven, and either twenty-one or twenty-eight. After exposure For individuals who have been potentially exposed to the virus, four doses over two weeks are recommended, as well as an injection of<unk>  immunoglobulin with the first dose. This is known as post-exposure vaccination. For people who have previously been vaccinated, only a single dose of the<unk>  is required. However, vaccination after exposure is neither a treatment nor a cure for<unk> ; it can only prevent the development of<unk>  in a person if given before the virus reaches the brain. Because the<unk>  virus has a relatively long incubation period, post-exposure vaccinations are typically highly effective. Additional doses Immunity following a course of doses is typically long lasting, and additional doses are usually not needed unless the person has a high risk of contracting the virus. Those at risk may have tests done to measure the amount of<unk>  antibodies in the blood, and then get<unk>  boosters as needed. Following administration of a booster dose, one study found 97% of immunocompetent individuals demonstrated protective levels of neutralizing antibodies after ten years.
