Booster dose:  Temporary reopening of a fourth vaccination centre in the hangar of the LAR at Findel

In order to offer all those concerned by a COVID-19 booster vaccine an additional opportunity to get vaccinated, the Government has decided to temporarily reopen the Luxembourg Air Rescue (LAR) vaccination centre at Findel. The LAR vaccination centre will open its doors this Friday 10 December. Details regarding opening hours can be found at

It should be noted that the vaccination centre will be used exclusively for the administration of booster doses by appointment.

The booster dose can of course be administered, without any invitation from the Government, by the general practitioner or in a "Pop Up"  vaccination spot. 

Pop Up Vaccination: "Lëtzebuerg léisst sech impfen"

To increase vaccination coverage, the Government has decided to facilitate access to vaccination by deploying temporary vaccination spots ("Pop Up"  Vaccination)  and mobile teams will be present in high-traffic areas (pedestrian zones, shopping malls, events organised by some municipalities).

The list of all new vaccination spots, which is constantly being extended and updated, can be consulted on the website

Incidence rates of those testing positive based on vaccination status reported since 6 December

The system in place for monitoring COVID-19 in Luxembourg is continuously adapted to produce indicators that reflect the evolution of the epidemic in real time.

From 6 December 2021, the incidence rates of new infections based on vaccination status are included in the daily reports. These new infections only concern people testing positive by PCR test. As a consequence, an adaptation of the key indicators of the daily status report will be put in place at this date on

The Excel file of the incidence rates of people testing positive based on vaccination status will be uploaded every Friday end of day on the website

The evolution of the variants

Variant sequencing data are published every Friday on the website of the National Health Laboratory (Laboratoire national de Santé, LNS)

Wastewater monitoring in Luxembourg as part of SARS-CoV-2

The level of contamination of the 13 sampled wastewater treatment plants studied by the LIST (Luxembourg Institute of Science and Technology) during the week of 29 November to 5 December showed a still high prevalence of SARS-CoV-2 in wastewater at national level. This week's results show a similar flow of SARS-CoV-2 as last week, with a stabilisation of the signal at a high level. A similar trend is also observed at regional level for most of the treatment plants analysed, with no regional disparities.

All CORONASTEP reports are available on the LIST website:
