Some pathogens require both antibody-mediated and cell-mediated immune responses to be neutralized and eliminated. A vaccine approach against these antigens must effitiently activate both components of the immune response.
In my case, we designed a recombinant vaccine against UTI. In this study, we took a sequence as adjutants in both humoral and cellular mediate immune response into consideration which we observed great result.
In my opinion, you can do so. If you have any other question, feel free to ask.
