Age-stratified neutralizing antibody titers against FPV, FCV, and FHV-1 following trivalent vaccination in cats aged ≤ 3 to ≥ 12 months. The y-axis represents the neutralizing antibody titer on a logarithmic scale with base 10. Box plots illustrate serum antibody titers by age group, from ≤ 3 months to ≥ 12 months, showing humoral immune responses to FPV, FCV, and FHV-1 in cats receiving either two or three doses of the trivalent vaccine. * indicates p < 0.05, ns indicate p > 0.05.
