Abstract
A simple mathematical model is presented to quantify the bias due to misclassification in prospective cohort studies of vaccine efficacy. Limitations of methods based on quantifying misclassification in 2 x 2 tables are discussed. The model is applied to data from three examples of the design and analysis of studies of pertussis vaccine efficacy.Mesh:
