BARDA continues long-standing partnerships with GSK, Sanofi, and Seqirus to strengthen preparedness and rapid response capabilities for influenza pandemics

About Image

BARDA is continuing partnerships with industry collaborators GlaxoSmithKline (GSK), Sanofi, and Seqirus to strengthen pandemic preparedness and response capabilities by ensuring ready production of medical countermeasures (MCMs), such as influenza vaccines and adjuvants, in the event of an influenza pandemic or other public health emergency.

The U.S. Department of Health and Human Services (HHS) continuously monitors pandemic risk in order to prepare to respond to the threats posed by novel influenza, including outbreaks caused by zoonotic influenza viruses. Within BARDA’s Division of Influenza and Emerging Infectious Diseases (IEID), the National Pre-pandemic Influenza Vaccine Stockpile (NPIVS) provides preparedness for influenza pandemics and maintains stockpiles of influenza vaccine antigens and adjuvants. The IEID Division works closely with its interagency partners and performs risk assessments to identify and evaluate potential pandemic influenza virus threats.

BARDA maintains the NPIVS inventory through public-private partnerships with domestic manufacturers of licensed influenza vaccines using egg-, recombinant protein-, cell-based vaccine, and oil-in-water adjuvant technologies. These partnerships seek to shorten timelines to make influenza vaccines available for the U.S. population in response to a pandemic.

Since 2005, BARDA has awarded contracts to domestic and licensed influenza vaccine manufacturers to sustain and expand the dynamic pre-pandemic influenza vaccine stockpile. This approach allows fast and continuous updates of pre-pandemic vaccines and adjuvants stockpiled for pandemic preparedness and enables a rapid response.

This partnership will build on the foundation laid out by the U.S. government’s previous investments and is aligned with the Executive Order (EO) 13887 on Modernizing Influenza Vaccines in the United States to Promote National Security and Public Health. The National Influenza Vaccine Modernization Strategy (NIVMS), 2020-2030, also outlines a vision for the U.S. influenza vaccine enterprise to be highly responsive, flexible, resilient, scalable, and more effective at reducing the impact of seasonal and pandemic influenza viruses.

These Indefinite Delivery Indefinite Quantity (IDIQ) contracts will provide BARDA with flexible and immediate access to MCMs, such as vaccines and adjuvants, for pandemic preparedness and response or as required in response to an HHS-declared Public Health Emergency; production of vaccines against influenza viruses and strains with pandemic potential; and production of vaccines and adjuvants to support U.S. government efforts to modernize influenza virus vaccines.
