The two antigens were purified using affinity chromatography and
administered to Swiss albino mice individually and in combination. Significant protection against
S. mansoni infection was observed in mice immunized with the Sm14/TrSm29 combination in the presence/
absence of the immunoadjuvant poly (I:C). The poly (I:C)-adjuvanted combination resulted in 40.3%,
68.2%, and 57.9% reduction in adult worm burden, liver egg burden and intestinal eggs, respectively.
Granuloma size and count were also reduced besides improvement of the histopathological picture of livers
of immunized mice. This study demonstrates the importance of using multi-antigen vaccines as an
effective and simple approach to fulfill enhanced protection against schistosomiasis
