摘要: We undertook a systematic review and meta-analysis of randomised controlled trials comparing typhoid fever vaccine with any alternative or inactive agent. Trials evaluating killed whole-cell vaccines were excluded. The cumulative efficacy at 3 years for the Ty21a polysaccharide Vi similar: 51% (95%CI 36%, 62%), 55% 30%, 70%), respectively. Vi-rEPA 3.8 was higher, 89% 76%, 97%), but this has not yet been licensed use evaluated in only one trial. Adverse events mild nature most, significantly more frequent groups when compared placebo. Both currently vaccine, are safe efficacious preventing fever. Neither is registered administration to children below 2 age. Given recent finding that also affects infants, development conjugate warranted.
