Abstract

After a single injection of purified Vi polysaccharide vaccine against typhoid fever, serum titres were followed in student volunteers by passive haemagglutination assay and by radioimmunoassay. Elevated Vi antibody titres were still present after 36 months. This preliminary study should be followed by further investigations on the extent and duration of protection provided by Vi vaccine, and on volunteers in endemic areas.
