Limited effect of duration of CMV infection on adaptive immunity and frailty: insights from a 27‐year‐long longitudinal study

Abstract

Cytomegalovirus-specific memory T cells develop shortly after CMV seroconversion but do not seem to further increase over time. Age-related effects other than duration of CMV infection seem to contribute to CMV-induced changes in the immune system. Although CMV-specific immunity is not evidently linked to frailty, it tends to associate with higher prevalence of cardiovascular disease.
