COVID-19 Vaccination Statistics Series 4

This publication is based on vaccinations administered up to 30 June 2022. It is a further publication by the Central Statistics Office (CSO) providing insights into Ireland's COVID-19 vaccination programme (COVID-19 Vaccination Statistics). This report is produced in collaboration with the Health Protection Surveillance Centre and Department of Health under the Statistics Act, 1993. The vaccination dataset used is provided to the CSO by the Health Service Executive (HSE).

Data Sources

For vaccination rates, the CSO uses data provided by COVAX (the HSE national immunisation registry for COVID-19 vaccination). Data were extracted from COVAX on 14/07/2022 and were correct at the time.

Revenue PAYE Modernisation system (PMOD) data is used to provide insight on employment status of records of vaccination from the HSE Vaccine Information System. Using pseudonymised identifiers more than 86% (2.5m) of employees aged over 18 on 01 January 2022 with a record of employment in the PMOD system in 2022 were linked to a record of vaccination (i.e. fully vaccinated, additional dose 1 or additional dose 2) in the HSE Vaccination Information System. Additional demographic information was derived by linking to the Department of Social Protection (DSP) Central Records System (CRS) using pseudonymised identifiers.

Please see Vaccination Data FAQ for further information.

Local Electoral Areas (LEA) assignment

LEAs are assigned through geocoding of addresses undertaken within the CSO (including using Eircodes provided in the COVAX dataset).

Vaccination Rates 

Fully vaccinated populations were defined as those who had a single valid dosage date record for a single-dose vaccine or two valid dosage dates for double dose vaccines recorded on Covax.

Additional dose vaccinations were defined as those individuals who had valid third / fourth / fifth dosage date entries for either the immuno-compromised or additional doses.

The vaccination rates should be interpreted as estimates. For example, the number of persons who have received a vaccine only includes those who have been vaccinated in the State and would not include those who may have been vaccinated outside of the State. Further, the denominators used for LEA rates are based on population estimates and for employee rates the denominator used is all those that have a record of employment in the State in 2022 and may include those living abroad and paid by an Irish enterprise or those who are no longer resident in the State. As rates are estimates, this may lead to an underrepresentation of the vaccination rates for a given grouping or LEA.

Data included in the corresponding PxStat tables to this bulletin (CDC45 and CDC46) is rounded in line with Statistical Disclosure Control (SDC) procedures.

In this bulletin, the following definitions apply:

• Fully Vaccinated - Those who had a single-dose vaccine or double dose vaccines. 
• Additional Dose 1 - Those who are fully vaccinated and have received their first booster vaccine (including immunocompromised dose).
• Additional Dose 2 - Those who are fully vaccinated and have received a first additional dose and their second booster vaccine (including immunocompromised dose). 

NACE Rev.2 Classification

The economic sector classification (NACE) is based on the ‘Statistical Classification of Economic Activities in the European Community, Rev. 2 (2008)' NACE Rev.2.

NACE codes were allocated accordingly as provided in PMOD.

EU labelling 

Nationality breakdown is consistent with EU labelling used in CSO Population and Migration Estimates updated in light of the United Kingdom (UK) leaving the European Union with effect from 01 February 2020. These labels can be mapped to those used in COVID-19 Vaccination Statistics Series 2.

EU13: countries before enlargement on 01 May 2004, (i.e. Austria, Belgium, Denmark, Finland, France, Germany, Greece, Italy, Luxembourg, Netherlands, Spain, Sweden, Portugal) (Ireland and UK Excluded).

EU14 to 27: defined as 10 countries that joined the EU on 01 May 2004 (i.e. Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, Slovenia), along with Bulgaria and Romania who joined on 01 January 2007 and Croatia who joined on the 01 July 2013.
