Answer

Currently, the 3 typhoid fever vaccines include injected Vi capsular polysaccharide (ViCPS; Typhim Vi, Pasteur Merieux) antigen, enteric Ty21a (Vivotif Berna, Swiss Serum and Vaccine Institute) live-attenuated vaccine, and an acetone-inactivated parenteral vaccine (used only in members of the armed forces). The efficacy of both vaccines available to the general public approaches 50%.
