Serotype replacement in disease after pneumococcal vaccination

Open access
Weinberger, Daniel M, Malley, Richard, Lipsitch, Marc·2011·The Lancet

Abstract

Vaccination with the protein-polysaccharide conjugate vaccine, PCV7, has significantly reduced the burden of pneumococcal disease in populations where it is in widespread use and has had an important public health benefit. This vaccine targets only 7 of the more than 92 pneumococcal serotypes, and there have been concerns that the non-vaccine serotypes (NVTs) could increase in prevalence and reduce the benefits of vaccination. Indeed, among asymptomatic carriers, the prevalence of NVTs has increased substantially, and as a result, there has been little or no net change in the carriage prevalence of the bacteria. In many populations, there has been an increase in pneumococcal disease caused by NVT, but in most cases this increase in NVT disease has been less than the increase in NVT carriage. In this article, we review the evidence for serotype replacement in carriage and disease and address the surveillance biases that might affect these findings. We then discuss possible reasons for the discrepancy between near-complete replacement in carriage and partial replacement for disease, and address the possibility that differences in invasiveness between vaccine serotypes and those causing replacement could contribute to this difference. We contend that the magnitude of serotype replacement in disease can be attributed, in part, to a combination of lower invasiveness of the replacing serotypes, biases in the pre-vaccine carriage data (unmasking), and biases in the disease surveillance systems that could underestimate the true amount of replacement. We conclude by discussing the potential for serotype replacement in disease in the future and the need for ongoing surveillance.

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.
