The efficacy of a new single post-exposure treatment of rabies in mice without vaccination

Local application of rabies immune serum and isoprinosine, an immunomodulator with antiviral activity was effective in mice infected with a sylvatic rabies virus. In this way, a single medical or veterinary treatment is only required, which is particularly important for developing but also for developed countries. The importance of using a post-exposure potency test to monitor rabies vaccines is emphasized. The same principle could be applied to other emerging viral infections of humans (for example, human immunodeficiency virus infection) and animals, for which no effective vaccines are available at this moment.
