An operational tool to estimate influenza disease burden averted through vaccination

Overview

The document “An operational tool to estimate influenza disease burden averted through vaccination” serves as a supplement to the WHO publication “A manual for estimating disease burden associated with seasonal influenza”. It provides public health officials and researchers with an approach to estimating influenza burden averted through vaccination. The model leverages available estimates of influenza disease burden to determine the burden that was averted where a vaccine campaign was conducted and the hypothetical burden that could have been averted if an influenza vaccine campaign had been conducted. Developed as an extension of the WHO manual, this operational tool cites, where appropriate, relevant section numbers from the WHO manual.
