[Antitetanus vaccination by Polan T in the elderly: followed of the immune response by Vaccitest T after vaccination and booster].

Tetanus vaccine activity without mineral adjuvant (Polan T) has been measured in a population of aged people (36 females and 11 males-mean age = 80.18 years). Titrations by hemagglutination of sensitized turkey red cells are performed before and after primo-immunization and first booster. This research gives knowledges regarding to the antitetanus response in elderly, regarding to the efficiency of the Polan T vaccine in this population uneasy to immunize and regarding to the quality of the simple and cheap assay for antitetanus antibodies titration.
