• Study comprised of 603 Midwestern veterinary students, ranging in age from 21 to 59, over a 6 year period (2004–2009).
• The incidence of inadequate titers after pre-exposure rabies vaccination at two years was 29.4%.
• Gender, vaccine manufacturer, BMI, and time between first and third doses were independently associated with inadequate titers.
BackgroundThis 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.MethodsA retrospective chart review of vaccination records of veterinary students in Michigan, 2004–2009, was conducted. Antibody titers <0.5 IU/ml as estimated by rapid fluorescent focus inhibition test were classified as inadequate. Variables were compared between the two groups to identify factors associated with inadequate titers at two years.ResultsA total of 603 subjects (mean age 24.1 ± 4.2 years, male:female 106:497) were included. Nearly one third (177/603, 29.4%) had inadequate titers at two years. Male gender (adjusted odds ratio (AOR) 1.87, 1.07–3.27; p = 0.029), vaccine manufacturer (AOR 1.49, 1.16–1.92; p = 0.002), BMI >25 (AOR 1.61, 1.02–2.54; p = 0.043), and duration between first and third doses of vaccine >21 days (AOR 2.49, 1.26–4.97; p = 0.009) were independently associated with inadequate titers.ConclusionsTwenty-nine percent of subjects had inadequate antibody titers against rabies at 2 years. Gender, vaccine type/manufacturer, BMI of 25 or greater, and more than 21 days between the first and third doses of vaccine were independently associated with inadequate antibody titers at two years. Our data would support modifying the recommendations, so the third dose is recommended at 21 days rather than 21–28 days.
