"Impf-Bus on tour"
The next stops of the "Impf-Bus on tour" will be announced on www.covidvaccination.lu.
Please note that the vaccination can be done without appointment (identity card and CNS card required). The type of vaccination offered is the initial vaccination and the booster dose.
Vaccinations in the "Impfbus" are done without prior appointment, which means that you have to wait for your turn, which can cause waiting times, especially during busy periods. In order to avoid long waiting times and for greater convenience, it is advisable to make an appointment at the vaccination centre, with a doctor or at a pharmacy.

Wastewater monitoring in Luxembourg as part of SARS-CoV-2
The CORONASTEP report is published every 15 days.
According to the latest CORONASTEP report drawn up by the LIST (Luxembourg Institute of Science and Technology), the contamination level of the 13 wastewater treatment plants analysed during the 37th and 38th week of 2022 shows a high prevalence of SARS-CoV-2 in wastewater. The contamination level of SARS-CoV-2 in wastewater seemed to be stabilised until week 37, but shows again a slight increasing trend since week 38. Similar trends were observed at regional level, with a constant level of SARS-CoV-2 in almost all wastewater treatment plants, with the exception of Mersch and Bleesbruck, where a significant increase was observed. However, further analysis is needed to confirm or not this upward trend.
All CORONASTEP reports are available on the LIST website: https://www.list.lu/en/covid-19/coronastep/.
