[Rabies virus antibody titers in dogs in Campo Grande, Mato Grosso do Sul State, during the anti-rabies campaign, 2003].

To assess the immune response in dogs attended during the 2003 anti-rabies animal vaccination campaign, 333 serum samples collected at different vaccination posts were analyzed. It was found that 51.1% of the animals did not have protective titers. No correlation was found between vaccine application or multiple vaccinations and higher immune titers.
