Natural Antibodies as Rheostats for Susceptibility to Chronic Diseases in the Aged.

abstract：:Long lasting antibody responses and immunological memory are the desired outcomes of vaccination. In general, multiple vaccine doses result in enhanced immune responses, a notable exception being booster-induced hyporesponsiveness, which has been observed with polysaccharide and glycoconjugate vaccines. In this study,...
