A few dogs in both the vaccinated and control groups have resisted numerous
exposures. It seems that if a dead virus will successfully immunize against rabies,
a stronger resistance should exist in dogs which have survived successive exposures
to a living virus.
Quite frequently cases of rabies have been reported in vaccinated dogs which
were exposed to the bite of a rabid dog previous to vaccination, but very little
data have been furnished on dogs which have been exposed to natural infection
subsequent to vaccination.
