Novavax’s Updated COVID-19 Vaccine Now Available in France

FOR MEDICAL AUDIENCES ONLY

Novavax’s updated protein-based non-mRNA COVID-19 vaccine is now available for use in France for the prevention of COVID-19 in individuals aged 12 and older. The vaccine is intended for adults and adolescents aged 12 and over, regardless of their vaccination history, but is not recommended for pregnant women pending further data, according to the National recommendation of the General Directorate of Health.

Our updated protein-based vaccine is now available for pharmacists and other healthcare providers to start vaccinating communities across France. As outlined in French vaccination recommendations, a diverse vaccine portfolio with both mRNA and non-mRNA options is critical to helping to protect communities across France against COVID-19 this vaccination season and in future.

The vaccine is being provided by the Ministry of Health and is available primarily in retail pharmacies beginning December 14, 2023, and in hospitals since December 7, 2023.
