Highly infectious and potentially life-threatening in infants, whooping cough, caused by the bacterium Bordetella pertussis, continues to circulate to a large extent throughout the world. Although the vaccines currently used protect against the onset of symptoms, they have limited durability and cannot prevent bacterial infection resulting in transmission between individuals.
To combat allergic asthma, which affects millions of people worldwide, scientists from Inserm, CNRS and Université Toulouse III-Paul Sabatier at the Infinity laboratory[1], Institut Pasteur and French company NEOVACS are developing and testing a new vaccine.
Une étude menée par une équipe de recherche de l’AP-HP, Université Paris Cité, l’Inserm, Sorbonne Université en collaboration avec AIDES et Coalition PLUS démontre à la fois l’efficacité d’un vaccin contre le méningocoque B dans la réduction du risque d’infection par le gonocoque et celle de l’utilisation de l’antibiotique doxycycline comme traitement préventif contre les infections sexuellement transmissibles, lorsqu’il est pris dans les 72 h suivant un rapport sexuel.
Scientists from the Institut Pasteur, Necker-Enfants Malades Hospital (AP-HP), Inserm in the Imagine Institute, Université Paris Cité and the Alfort National Veterinary School (EnvA) have identified a previously unknown species of circovirus, provisionally named human circovirus 1 (HCirV-1). Circoviruses are a family of small, highly resistant DNA viruses that were initially identified in 1974 in various animal species, where they can cause respiratory, renal, dermatological and reproductive problems. HCirV-1...
Aedes mosquitoes are the principal vectors of dengue and other arboviruses, including Zika, for which no vaccines or antiviral treatments currently exist. Understanding the factors that influence the transmission of arboviruses from mosquitoes to humans is therefore a priority because it could guide the implementation of public health measures that could limit or even prevent epidemics. In a new study, a team of researchers from Inserm, CNRS and Université...
Emulsifiers are food additives that are used to improve texture and extend shelf life. They are found in many processed products (ice cream, packaged cakes, sauces, etc.) despite having demonstrated harmful effects on intestinal balance. In a new study, scientists from Inserm, CNRS and Université Paris Cité at Institut Cochin in Paris sought to counteract these effects by using Akkermansia muciniphila, a bacterium naturally present in the intestine, to...
Ebola epidemics occur periodically in various sub-Saharan African countries. While vaccines exist and have already received WHO Prequalification against the Zaire ebolavirus species, it is essential to pursue and intensify efforts to supplement the available data to develop a safe and effective Ebola vaccine strategies in adults and children alike. The PREVAC international consortium, which includes scientists from Inserm and from institutions in Africa, USA and UK, has...
La tuberculose touche 1 million d'enfants chaque année dont moins de la moitié sont diagnostiqués et traités, ce qui entraîne plus de 200 000 décès par an. Dans une nouvelle étude, des chercheurs et cliniciens de l’Université de Bordeaux, de l'Institut de recherche pour le développement (IRD) de l’Inserm et MU-JHU (collaboration de recherche entre l’Université de Makerere et l’Université de John Hopkins en Ouganda) regroupés au sein du...
The ANRS DOXYVAC trial, conducted by a research team from the Paris public hospitals group (AP-HP), Université Paris Cité, Inserm and Sorbonne Université in collaboration with AIDES and Coalition PLUS, demonstrates the efficacy of both a meningococcal B vaccine in reducing the risk of gonorrhea infection and the use of doxycycline as preventive intervention for sexually transmitted infections when taken within 72h after sexual intercourse.
How can we increase the efficacy of vaccines used to protect against viral respiratory diseases such as influenza and COVID-19? Scientists from Inserm, CNRS and Aix-Marseille Université at the Center of Immunology Marseille-Luminy are opening up new prospects in the field, with the triggering of memory B cells directly in the lungs looking to be a promising avenue. At present, the vaccines are administered intramuscularly and do not trigger...
