Abstract

BACKGROUND: Immune function declines with age and has been associated with reduced vaccine responsiveness. Chronic infection with cytomegalovirus (CMV) has been proposed as a contributor to poorer responses in older adults. A pneumococcal vaccine has been recommended in the United Kingdom for those aged >65 years since 2003 to prevent pneumococcal disease. METHODS: We evaluated the effect of age and CMV status on pneumococcal vaccine responses in 348 individuals aged 50-70 years. RESULTS: We found participant age to be associated with serotype-specific and functional antibody titers after pneumococcal vaccination, with a mean 6.2% (95% confidence interval, 2.9%-9.5%) reduction in postvaccination functional antibody titers per year. CMV status was not associated with serotype-specific immunoglobulin G concentrations or functional antibody titers after pneumococcal vaccination. However, CMV seropositivity was associated with higher levels of prevaccination functional antibody for 4 of 7 pneumococcal serotypes assessed. CONCLUSIONS: These data imply that CMV infection is not directly responsible for the decline in pneumococcal vaccine responses seen with age but suggest that CMV-seropositive individuals differ in their natural exposure to pneumococci or have altered mucosal immune responses after colonization with this organism.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Some studies have shown no effect of CMV on vaccine responses in the elderly.

    “For example, some studies have shown no effect of CMV on vaccine responses in the elderly (den Elzen et al. 2011; O’Connor et al. 2014; Wald et al. 2013) and other studies have even reported vaccine-boosting effects of CMV in young individuals (Furman et al. 2015).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
