• Seqirus will offer FLUAD® QUADRIVALENT (Influenza Vaccine, Adjuvanted), which is now preferentially recommended by the CDC’s Advisory Committee for Immunization Practices as one of the preferred vaccine options for adults 65 years and older, over standard-dose influenza vaccines

• Seqirus is officially recognized by the U.S. government as having successfully established domestic manufacturing capability for innovative cell-based seasonal and pandemic influenza vaccines.
• Holly Springs, N.C., facility is ready to deliver 150 million doses of pandemic influenza vaccine to the U.S. government in the event of an influenza pandemic.

• Renewal reaffirms longstanding, public-private partnership between Seqirus and the Biomedical Advanced Research and Development Authority (BARDA) to strengthen preparedness and rapid response capabilities for influenza pandemics
• Agreement includes provision for Seqirus to provide BARDA with supply of AUDENZ, the first-ever FDA-approved adjuvanted, cell-based pandemic influenza vaccine, which was developed in partnership with BARDA

New facility in Waltham, Massachusetts, will support CSL’s growing R&D portfolio, including the self-amplifying mRNA technology platform, the next generation of mRNA vaccine technology, for seasonal and pandemic influenza vaccines.

• The FDA has granted approval of multi-dose vial presentation for AUDENZ™ to help protect individuals six months of age and older against influenza A(H5N1) in the event of a pandemic.
• As the first-ever adjuvanted, cell-based influenza vaccine, AUDENZ™ was originally approved by the FDA in February 2020 in prefilled syringe presentation.
• This approval marks an important milestone in the company’s pandemic preparedness efforts in partnership with Biomedical Advanced Research and Development Authority (BARDA).

• Approval aligns with universal age recommendation for all eligible people six months and older to receive annual influenza vaccination 1
