We characterized cytokine profiles of CD4+T-helper (h) cells in adults and young children to ascertain if responses occur to next-generation candidate vaccine antigens PspA, PcpA, PhtD, PhtE, Ply, LytB of Streptococcus pneumonia (Spn) and protein D and OMP26 of non-typeable Haemophilus influenzae (NTHi). Adults had vaccine antigen-specific Th1 and Th2 cells responsive to all antigens evaluated whereas young children had significant numbers of vaccine antigen-specific CD4+T cells producing IL-2, (p=0.004). Vaccine antigen-specific CD4+T-cell populations in adults were largely of effector (TEM) and/or central memory (TCM) phenotypes as defined by CD45RA−CCR7+or CD45RA−CCR7−respectively; however among young children antigen-specific IL-2 producing CD4+T cells demonstrated CD45RA+expression (non-memory cells). We conclude that adults have circulating memory CD4+T cells (CD45RA−) that can be stimulated by all the tested Spn and NTHi protein vaccine candidate antigens, whereas young children have a more limited response.
