This report presents pooled COVID-19 vaccine effectiveness (VE) estimates for the first, second and third booster doses (compared to complete primary vaccination with no booster) against hospitalisation due to COVID-19 and COVID-19-related death in resident populations ≥50 years of age living in the community.

The SARS-CoV-2 Omicron variant of concern (VOC) is rapidly replacing SARS-CoV-2 Delta in most European Union/European Economic Area (EU/EEA) countries, and is broadly following a west-to-east progression.
The risk to public health posed by the spread of the Omicron VOC in the context of ongoing Delta VOC transmission in the EU/EEA is assessed in this update.
The number of countries reporting SARS-CoV-2 Omicron variant of concern (VOC) cases continues to increase globally, with a total of 352 confirmed cases reported by 27 countries as of 16.00 on 1 December 2021, including 70 confirmed cases reported by 13 European Union and European Economic Area (EU/EEA) countries.
A SARS-CoV-2 variant belonging to Pango lineage B.1.1.529, with a high number of S-gene mutations compared to the original virus was detected at the beginning of November 2021. On 26 November 2021 the variant was designated a variant of concern (VOC) and assigned the label Omicron by the World Health Organization (WHO).
This Rapid Risk Assessment assesses the risk posed by the circulation of the Delta variant of SARS-CoV-2 between 1 December 2021 to 31 January 2022, based on modelling scenarios and projected levels of vaccination coverage.
The risk assessed in this update is as follows: based on current levels of vaccination coverage and the dominance of the Delta variant in the EU/EEA, what risk does SARS-CoV-2 pose to the general population and the vulnerable population in the coming months?
The aim of this threat assessment brief is to assess potential public health implications of the spread of the SARS-CoV-2 Delta (B.1.617.2) variant of concern for the EU/EEA.
