The SARS-CoV-2 coronavirus infects human cells through the interaction of the viral envelope Spike protein (IPR044366) with the human Angiotensin-Converting Enzyme 2 (ACE2), expressed at the surface of target cells. Here, we describe a detailed protocol to measure the b...

To control the evolution of a pandemic such as COVID-19, knowing the conditions under which the pathogen is being transmitted represents a critical issue, especially when implementing protection strategies like social distancing and face masks wearing. For viruses and b...

International audience; Using open-ended questions, this study explored parents’ experiences regarding changes in their family’s food-related behaviours during the first COVID-19 lockdown in France (March- May 2020). Parents (N=498, 72% mothers) of children aged 3-12 ye...

International audience; Supercritical Carbon Dioxide treatment of clean and soiled Filtering Face-Piece respirators is shown to meet mandatory requirements for safe reuse of FFP2. Preliminary tests enabled us to select optimal conditions for Supercritical Carbon Dioxide...

Abstract The tension on the supply of surgical and FFP2 masks during the first wave of the COVID-19 pandemic leads to study the potential reuse of these masks. As washing is easily adaptable at home, this treatment solution was retained. In this work, thirty-six referen...

The need for personal protective equipment increased exponentially in response to the Covid-19 pandemic. To cope with the mask shortage during springtime 2020, a French consortium was created to find ways to reuse medical and respiratory masks in healthcare departments....

International audience; BACKGROUND: Measuring vaccine effectiveness (VE) using real-life data is critical to confirm the effectiveness of licensed vaccine, which could strengthen vaccination adherence. METHODS: We measured VE against adult COVID-19 hospitalization in fi...

SARS-CoV-2 infection is mediated by the interaction of the spike glycoprotein trimer via its receptor-binding domain (RBD) with the host's cellular receptor. Vaccines seek to block this interaction by eliciting neutralizing antibodies, most of which are directed toward ...

International audience; La fin du XXe siècle avait vu s’affirmer dans les représentations ordinaires l’idée que l’histoire du continent européen conduirait, au long d’un cheminement sinon « naturel » du moins cohérent et irréversible, de l’âge des frontières et des nati...
