When examining the differential lymphocyte counts, all cats in the non-vaccinated group showed a 75% or greater reduction in lymphocyte count and monocyte count on at least one occasion following challenge. All cats in the non-vaccinated group also showed at least a 50% reduction in neutrophils on at least one occasion post challenge; 4 of the 6 cats showed a reduction greater than 75% from baseline. None of the cats in the simultaneous administration group showed significant reductions in their lymphocyte, neutrophil or monocyte counts on any occasion post challenge. In the concurrent administration group, none of the cats showed significant reductions in their lymphocyte counts post challenge, but 2 cats showed a 50%, or greater, reduction of their neutrophil counts post challenge and 1 cat showed a 50%, or greater, reduction in their monocyte count post challenge.
All cats in the concurrent and simultaneous administration groups increased their antibody levels to FPV from
