COVID-19 vaccination roll-out and uptake among refugees and migrants in Greece: a retrospective analysis of national vaccination routine data

OBJECTIVES

Refugees and migrants (R&Ms) exhibited higher risk of COVID-19 infection, and higher mortality rates during the pandemic. Acknowledging these risks, R&Ms early in the pandemic were identified by WHO as a priority vaccination group in need of protection. The aim of this study was to assess the vaccination roll-out and uptake among R&Ms residing in Reception Identification Centers (RICs) and Reception Sites (RSs) in Greece, relative to the general population.

STUDY DESIGN

Nationwide observational study.

METHODS

Retrospective analysis of national vaccination routine data and population census data, collected and triangulated from multiple official/governmental sources. Weekly vaccine roll-out and uptake were calculated for the general Greek population and the R&M population, through the first year of the vaccination programme in Greece (December 2020-December 2021).

RESULTS

Vaccine roll-out among migrants in RICs/RSs started with a 22-week delay, compared to the general population. By the end of the first year of the vaccination programme in Greece in December 2021, the national vaccination uptake among registered R&Ms residing in official reception facilities was 27.3 % for 1st dose and 4.7 % for booster dose; considerably lower compared to the general population (69.5 % uptake for 1st dose, 64.7 % for 2nd dose, and 32.0 % for 3rd dose).

CONCLUSION

Delayed vaccine roll-out and low vaccine uptake among R&Ms in Greece are signs of low prioritisation and implementation failures in the R&M vaccination strategy. In face of future public health threats, lessons should be learned, and vaccine equity should be insured for all socially vulnerable and high-risk population groups.
