Although vaccine efficacy is traditionally reported as a relative measure of disease incidence (eg 90% efficacy), the consideration of absolute estimates of disease prevented is necessary for a complete assessment of vaccination effects. 1, 2 This is particularly relevant for studies in which the endpoint definition has a low sensitivity. In these situations, a specific endpoint definition is needed to estimate relative efficacy, but additional analyses using a sensitive definition and estimates of rate differences are needed to understand the burden of disease prevented.Culture-confirmed invasive pneumococcal disease is the current standard and most specific endpoint for randomized controlled studies that evaluate the efficacy of pneumococcal vaccines in preventing invasive disease. Importantly, cultures help identify pneumococcal serotypes and characterize patterns of antibiotic susceptibility. However, pneumococcal cultures have low sensitivity, 3 and incidence estimates based on culture results alone underestimate the real disease burden. In contrast, the identification of compatible episodes of invasive disease that lack culture confirmation can be more sensitive and could better capture the burden of pneumococcal disease. Nevertheless, this approach to identify suspected invasive pneumococcal disease is less specific, includes some false cases and leads to misclassification of study endpoints.
