The aim of this study was to identify the seroprevalance rate of tetanus and to determine missed opportunities for tetanus vaccination. Two hundred and twenty-seven female volunteers who were hospitalized following delivery participated in the study. Blood samples were analyzed using enzyme-linked immunoassay to measure tetanus antibody levels. In addition, a questionnaire was used to investigate the factors associated with vaccination status. Sixty-five percent of the study participants had safe protective levels of antibodies. Factors associated with antibody level were age, level of education and number of doses.
