Intravenous injection of polyinosinic acid/polycytidylic acid [(poly rI)·(poly rC)] offered significant protection against intranasal challenge of young mice with vesicular stomatitis virus (VSV). Optimal protection was obtained when a single dose was administered 2 hr before virus challenge, but repeated doses were effective when started as late as 3 days after virus challenge. The therapeutic ratio or ratio of maximum tolerated dose to minimum effective dose for a single intravenous injection of (poly rI)·(poly rC) 2 hr before virus inoculation was ≥8 mg/kg:0.004 mg/kg or ≥200.
