Dynamical modelling of COVID-19 pandemic and its path towards herd-immunity

It is my pleasure to invite you to our first LSS Presentation of 2021, to take place on March 4, from 8pm – 9pm via Microsoft Teams . The talk will be given by Françoise Kemp from the University of Luxembourg. She got a Master in Applied Mathematics from the University of Trier in 2018, and is now doing a PhD in Systems Biomedicine at the Luxembourg Center for Systems Biomedicine, and is Member of the COVID-19 Taskforce Research Luxembourg


Against the current COVID-19 pandemic, non-pharmaceutical interventions have been widely applied; vaccines are also becoming available. Now, an urgent question is how the interplay between vaccination strategies and social measures will shape infections, hospital demand and casualties. Hence, we extend the Susceptible-Exposed-Infectious-Removed (SEIR) model to include vaccination, ICU, hospital and death. We calibrate it to data of Luxembourg, Austria and Sweden. The model quantifies the vaccination rate needed for herd immunity by desired times. Aiming to vaccinate the whole population within 1 year at a constant rate could lead to herd immunity only by mid-summer. Herd immunity might not be reached in 2021 if too slow vaccines roll-out speeds, which we quantify, are employed. Vaccination will help considerably, but not immediately, thus social measures still remain crucial for months.

International Conference on Accounting & Assessment in Statistics (ICAAS) 2021

National and Business Accounts for Sustainable Development Policies

The International Conference on Accounting & Assessment in Statistics (ICAAS) 2021 is a online conference, based on the overarching need to discuss ongoing developments on this topic in response to policy needs. ICAAS is held to address the issues of statistical methodologies and thematic applications in accounting and assessment. Discussions will focus on the new tools provision, particularly in the areas needed for sustainable development policies.

Several questions arise: which kind of information is needed for Sustainable Development? To what extent these information needs can be met by accounting in statistics? Which data are already available and which missing data should be collected? Which are the statistical issues to be addressed and the limits of this approach? Which are the best experiences and practices developed in this area? These and further issues in methodological and applied statistics: contributions are expected on both these areas.

The Luxembourg Statistical Society (LSS) is organizing the event with the support of FENStatS, Statec, Eurostat, University of Luxembourg, PWC-Luxembourg and the IARNIW of India.
