Seasonal influenza vaccination coverage: EHIS survey results versus OECD statistics

Abstract

Seasonal influenza vaccination is one of the most important tools of prevention. Countries currently use many different methodologies to measure national influenza vaccine coverage in populations at higher risk. The study uses two main data sources: The European Health Interview Survey (EHIS) (collected by Eurostat) and OECD statistics, and compares both results. Findings showed that the EHIS survey results observed in this study are mainly lower than OECD data. This can mean that international sources provide overestimated data of coverage compared to outcomes from population surveys.
