Summary of WHO and UNICEF Immunization Coverage Estimates for Austria (2021 Revision)

Overview

This report details WHO and UNICEF's estimates of national immunization coverage in Austria for key vaccines, based on data received as of July 7, 2022. The estimates cover periods from 2010 to 2021 and reflect the performance of the immunization system.

Vaccines Covered

BCG vaccine: Covers 2010-2021.
DTP1/ DTP3 and Pol3 vaccines: Covers 2010-2021, focusing on children aged 4 years as of December of each year.
IPV1 vaccine: Introduced in 2015, covering 2015-2021.
MCV1/MCV2 and RCV1 vaccines: Covers 2010-2021, with estimates for RCV1 based on MCV1 data.
HepBB/HepB3 and Hib3 vaccines: Covers 2010-2021.
RotaC and PcV3 vaccines: Covers 2010-2021, with constant estimates for RotaC.
YFV vaccine: Covers all years, annually impacted by epidemics.

Methodology

Estimates use a variety of data sources, including reported national data, surveys, administrative reports, and agent-based simulation models to handle missing data or COVID disruptions.
Graded confidence (GoC): Ranges from "No accepted empirical data" to "High confidence," with methodologies applied case-by-case.
COVID-19 disruptions influenced data reporting; estimates post-2019 rely on simulation models due to lack of independent assessments.

Key Findings

Coverage generally shows high levels for many vaccines (e.g., DTP1 and MCV1 around 90-95%).
Some years have missing data, leading to extrapolation or interpolation.
Confidence levels vary: Many estimates have low confidence due to data limitations or lack of independent verification.

Caveats

All estimates should be used with caution due to potential data biases.
Recommendations for high-quality independent assessments are noted where reported levels may be overestimated.
COVID-19 impacts on data collection were evident, affecting reliability in certain years.
