Abstract
A single intranasal inoculation of St. Louis encephalitis virus protected 65% of 3- to 4-week-old rats against Western equine encephalomyelitis virus subsequently inoculated by the same route. The percentage of animals protected was increased to 95% if 3 inoculations of St. Louis encephalitis virus preceded the Western equine encephalomyelitis virus.Keywords
