Antibody response to influenza vaccination in the elderly: A quantitative review

GOODWIN, K, VIBOUD, C, SIMONSEN, L·2006·Vaccine

Abstract

We performed a quantitative review of 31 vaccine antibody response studies conducted from 1986 to 2002 and compared antibody responses to influenza vaccine in groups of elderly versus younger adults. We did a weighted analysis of the probability of vaccine response (measured as seroconversion and seroprotection) for each vaccine component (H1, H3 and B antigens). Using a multiple regression model, we adjusted for factors that might affect the vaccine response. The adjusted odds-ratio (OR) of responses in elderly versus young adults ranged from 0.24 to 0.59 in terms of seroconversion and seroprotection to all three antigens. The CDC estimates of 70-90% clinical vaccine efficacy in young adults and these estimates suggest a corresponding clinical efficacy in the elderly of 17-53% depending on circulating viruses. We conclude that the antibody response in the elderly is considerably lower than in younger adults. This highlights the need for more immunogenic vaccine formulations for the elderly.

  • A meta-analysis of more than 30 studies found lower seroconversion and seroprotection odds in elderly versus young adults for influenza vaccine antigens.

    “A meta-analysis of more than 30 studies demonstrated unadjusted odds ratios (OR) of 0.48 (95% CI: 0.41–0.55 for H1N1 Ag); 0.63 (0.55–0.73; H3N2 Ag) and 0.38 (0.33–0.44; B Ag) for seroconversion (HAI titer increase 4-fold) and 0.47 (0.40–0.55; H1N1 Ag), 0.53 (0.45–0.63; H2N3 Ag), and 0.58 (0.50–0.67; B Ag) for seroprotection (HAI ≥40) in a comparison of elderly versus young adults [150].”

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.
