Sanofi says FDA approves Fluzone High-Dose Quadrivalent for older adults
The FDA has approved a supplemental Biologics License Application for Fluzone High-Dose Quadrivalent for use in adults 65 years of age and older. Fluzone High-Dose was approved by the FDA in 2009 as a trivalent influenza vaccine, including two influenza A strains and one influenza B strain. Fluzone High-Dose Quadrivalent contains an additional influenza B strain. Fluzone High-Dose Quadrivalent is given to people 65 years of age and older to help prevent influenza disease caused by influenza A and B strains contained in the vaccine. This approval is the final step toward the company's complete transition to quadrivalent influenza vaccines in the U.S. Fluzone High-Dose Quadrivalent will be made available for immunization efforts during the 2020-2021 influenza season. Sanofi Pasteur will continue to deliver and offer the trivalent formulation of Fluzone High-Dose through the end of the 2019-2020 influenza season.
