COVID-19-vaccination for children aged 5-11 years: now open in 3 vaccination centres

From 23 December, children aged between 5 and 11 years can be vaccinated on a voluntary basis in the 3 vaccination centres Victor Hugo, Esch-Belval and Ettelbruck.

The vaccination of children will not be possible in temporary vaccination spots ("Pop Up" Vaccination). The child must be accompanied by a legal guardian.

Which vaccine?

Children will be vaccinated with the vaccine Comirnaty from Pfizer and BioNTech. Note that the dose for children aged between 5 and 11 years is lower (with an adapted dosage of 10 µg) than that recommended for children aged 12 years and over, i.e. 1/3 of the dose will be given to children.

Booking an appointment

The appointment can be made on with the child's social security card number.

The vaccination can also be carried out by certain paediatricians. The list of paediatricians participating in the vaccination of children will be published shortly

"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).

Closing of the "Pop-up" Grand-Rue

The vaccination spot in the center of Luxembourg City will close its doors from 31 December 2021, as the premises will have to be vacated.

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 20 to 26 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 the last 2 weeks, 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:
