Immune Booster 30: Infant Immunology with Martha Alexander-Miller

Infant immune systems are uniquely wired for tolerance, leaving infants under six months highly susceptible to disease and poorly responsive to standard vaccines. Addressing this vulnerability requires specialized vaccine platforms that incorporate specific immunostimulatory adjuvants. Research using non-human primate models demonstrates that combining these adjuvants can successfully drive neutralizing antibody production and enhance effector functions in newborns. Unlike the immune exhaustion observed in the elderly, infant immune systems require tailored formulations to overcome developmental limitations. Martha Alexander-Miller, a professor at Wake Forest University School of Medicine and co-director of the Center for Vaccines at the Extremes of Aging, highlights that these targeted signals are essential for mounting protective responses. Effective immunization strategies must account for the distinct physiological needs of the youngest populations, moving beyond one-size-fits-all approaches to ensure robust protection against infectious threats.
