Abstract
We describe a Dot-ELISA system for the rapid, specific and reliable assessment of a subject's antitetanus immune status. The conditions for Dot-ELISA were selected to give positive reactions only for sera with antitetanus antibody titers equal to or higher than 0.06 I.U./ml, considered to represent protection when using “in vitro” methods. This Dot-ELISA method could advantageously be applied to the monitoring of vaccination campaigns, as well as for assessing the antitetanus immune status of the wounded.
