Incidence and variables associated with inadequate antibody titers after pre-exposure rabies vaccination among veterinary medical students.

Background: This study sought to determine the proportion of subjects with inadequate antibody titers at two years after pre-exposure rabies vaccination and identify variables associated with inadequate antibody titers.

Methods: A retrospective chart review of vaccination records of veterinary students in Michigan, 2004-2009, was conducted. Antibody titers <0.

Age-related hepatitis B seroconversion rates in health care workers.

Prevalence of congenital deficiency in serum cholinesterase.

The results of studies in Europe indicate a 4% prevalence of congenital serum cholinesterase deficiency. Prevalence rates in the United States have not been reported.
