Upon first vaccination, the humoral immune response is activated where the attenuated pathogen interacts with the b cell that has matching antibodies. The b cell engulfs the pathogen by phagocytosis and presents the antigens on the MHC II markers on the cell's surface. The Th cell binds to the complementary antigen on the MHC II marker and secretes cytokines, that stimulate the B cell to undergo clonal expansion and produce B plasma cell and B memory cells

Does anyone know if the cell-mediated response has to occur before the humoral response in order to have T helper cell? Cause I have a question that asks if HIV stimulates a cell-mediated or humoral response and i am unsure.
