Abstract
Influenza vaccination is the primary strategy for preventing influenza and its severe complications. Because influenza vaccine has been used internationally for a long time, the methodologies used to evaluate influenza vaccine efficacy/effectiveness have also changed over time. In this chapter, we provide an overview of the epidemiological approaches to assess influenza vaccine efficacy/effectiveness with reference to the fundamental principles of epidemiology. We also highlight the test-negative design, a modified case-control study, because it is currently the most desirable epidemiological approach for evaluating influenza vaccine effectiveness against laboratory-confirmed influenza. Evidence of vaccine effectiveness from test-negative design studies, global trends to monitor vaccine effectiveness using test-negative design across the seasons, inherent limitations of the current influenza vaccines in terms of effectiveness, available influenza vaccines worldwide, as well as future perspectives for vaccine development are also discussed.
