Animal Vaccination
Several animal vaccines have been made to protect against RVF infection. The first one to be developed was a live vaccine. When administered to mice, the results were promising; this vaccine provided immunity for three years. However, a problem was encountered: administration to pregnant ewes on many occasions led to abortion. Since then, attenuated vaccines have been developed. Although they are protective and do not cause adverse effects, these results are only achieved after multiple inoculations, which may prove problematic, especially in areas where RVF is endemic.
