In late August 2026, French health insurance (Assurance Maladie) increased the reimbursement rate for two Respiratory Syncytial Virus (RSV) preventive treatments from 30% to 65%. This change followed a re-evaluation by the Haute Autorité de Santé (HAS), which upgraded the medical benefit of Pfizer’s Abrysvo vaccine and the Sanofi/AstraZeneca injectable Beyfortus from ‘moderate’ to ‘important’ in preventing RSV-related bronchiolitis. Following these adjustments, France launched a national prevention campaign against infant bronchiolitis scheduled to run from September 14, 2026, through February 2027. The medical arsenal for this season expanded to include a new monoclonal antibody, Enflonsia (clesrovimab), alongside Beyfortus and Synagis, which remains reserved for high-risk or premature infants. Abrysvo continues to be an option for pregnant women. In French overseas territories, the prevention schedule is staggered, beginning in the French Antilles in late August and continuing through various dates in La Réunion, Mayotte, and French Guiana. ## Timeline ### 2026-09-05: France launches new bronchiolitis prevention campaign France is launching its 2026-2027 bronchiolitis prevention campaign, introducing the monoclonal antibody Enflonsia to combat RSV in infants alongside existing vaccination and antibody options. 2 sources. https://clstr.news/cluster/france-launches-new-bronchiolitis-prevention-campaign ### 2026-08-21: France increases reimbursement for RSV preventive treatments France will increase the reimbursement rate for RSV preventive treatments Abrysvo and Beyfortus from 30% to 65% in late August to better protect infants from bronchiolitis. 3 sources. https://clstr.news/cluster/france-increases-reimbursement-for-rsv-preventive-treatments --- Cite as: France RSV prevention and reimbursement measures.
