Author manuscript; available in PMC 2011 Could 1.Welsh et al.Page11.Responses title= AJPH.2015.302719 towards the heterologous epitopes. Probably vaccines should be engineered to delete epitopes that may interfere with all the preferred target response (148). As one more example, provided the observed epitope-dependent heterologous immunity reported and discussed above in between IAV and HCV (68,155), would it not be wise to delete the cross-reactive epitope from any reside HCV vaccine? The damaging effects of heterologous immunity need to, not surprisingly, be balanced with its optimistic effects. Mouse model research have indicated that most of the time heterologous immunity can be a superior point for the host (Fig. 1), in that it usually leads to a lot more speedy clearance in the virus and, actually, can lower mortality when the host is exposed to typically lethal doses of virus (96). With all the collection of the right cross-reactive epitopes, there perhaps might be manufactured a vaccine that would give fantastic protective immunity but not immunopathology against a wide range of pathogens.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptAcknowledgmentsThis work was supported by United states National Institutes of Overall health (NIH) Study Grants AI017672, AI081675, AI073871, AI46692, AI046578, AI049320, AI054455, and AI073540.
