Comparison of two commercial vaccines against visceral leishmaniasis in dogs from endemic areas: IgG, and subclasses, parasitism, and parasite transmission by xenodiagnosis

No significant differences were observed in dogs vaccinated with Leishmune® or Leish-Tec®, with respect to LVC clinical aspects, parasitism, IgG seropositivity, or dog infectiousness. The Leishmune®-vaccinated animals presented higher levels of IgG, IgG1, and IgG2. The animals vaccinated with Leish-Tec® exhibited adverse reactions with greater frequency and severity.
