The main potential areas of bias in economic evaluation (EE) in health care can be categorised as follows: (1) choosing the study question and design, (2) estimating clinical effectiveness; (3) choosing cost data sources, and (4) reporting and dissemination of results. Each of these is discussed while focusing on vaccines. ⋯ This paper explores the differences between them in relation to the four areas of bias. Finally, remedies to avoid bias in research and publications are proposed and discussed.
