Typhi Omp-specific adaptive immune responses evolve over a period of at least two months after vaccination
Typhi Omp-specific adaptive immune responses evolve over a period of at least two months after vaccination. == Materials and methods == == Subjects, vaccination and sample collection == This open, interventional study was approved by the Ethics Commission of the Canton St. in stool peaked at day 60. Similarly, Omp-specific CD4+T cells in peripheral blood showed the highest expansion at day 60 post vaccination, concomitant with a significant increase in IFN- and TNF production. These results indicate thatS. Typhi Omp-specific B cell responses and polyfunctional CD4+T cell responses evolve KDR antibody over a period of at least two months after application of the live attenuated vaccine. Moreover, these findings underscore the potential ofS. Typhi Omps as subunit vaccine components. Trial registration:ISRCTN18360696 == Introduction == Salmonellaenterica serovar Typhi (S. Typhi) is…
