HEV71 in Vitro Neutralizing antibody titer serum. The 2-fold diluted serum IgG shows elevation in neutralizing titer compared to saliva IgA. The dual immunized group display neutralizing IgG titer of (64). Low titer shown among those singe routes immunized groups; the chitosan encapsulated nano-cap vaccine displaying high neutralizing antibody titer (8 and 16), the vaccine loaded chitosan without adjuvant (8) and vaccine encapsulated in alginate (8).compared to the unvaccinated group. The reciprocal titer represents the sample dilution of with neutralizing titer above 50% labeled (+), (P = 0.0015).
