The newly emergent 2009 H1N1 influenza virus is a novel virus with pandemic potential. Consistent with the National Strategy for Pandemic Influenza, HHS is committing funds for the production of pilot lots for clinical studies, as well as a bulk supply of antigen and adjuvant for use in a potential vaccine for the 2009 H1N1 which will become a part of the national stockpile of pre-pandemic influenza vaccines.

A vaccine is made from a virus or bacteria (referred to as an antigen), which causes the human body’s immune system to develop antibodies against a specific virus or bacteria so the body can recognize and fight the virus or bacteria. Adjuvants may be added to a vaccine to help generate a stronger immune response so less vaccine is needed for the body to recognize and fight a virus or bacteria.

Vaccine Development

When the 2009 H1N1 strain was isolated and identified as a novel influenza virus, work began to prepare a virus reference strain. This is a standard practice when new influenza strains are discovered, where a clinical sample of the virus is mixed with another influenza virus that grows in eggs to develop a new virus that has some of the properties of the novel virus and the ability to grow in eggs. This work is necessary in order to create an influenza vaccine using conventional methods.

Once a virus reference strain is ready, it will be made available to influenza vaccine manufacturers in order to create a master virus seed, which prepares a virus to be used in making the vaccine.

Health and Human Services (HHS)Contracting Activities

Since 2004, HHS has contracted with manufacturers that currently hold U.S. licenses for flu vaccine as part of the National Strategy for Pandemic Influenza. In May 2009, HHS issued new orders on these contracts to produce a bulk supply of vaccine antigen and adjuvant and to produce pilot (also called investigational) lots of a 2009 H1N1 vaccine. Most will be stored in bulk, and a small amount will be prepared as vaccine for use in clinical studies to evaluate vaccine safety and the dosage required for a protective effect. This research will include studies with adjuvant to determine its safety and the effect it would have on the immune system’s response.

FDA Approves New Influenza Vaccine Production Facility

The U.S. Food and Drug Administration (FDA) today announced that it has approved a new manufacturing facility used to produce influenza virus vaccines.  The facility is approved for seasonal influenza vaccine production and could be used for the production of vaccine against the new 2009 H1N1 influenza strain.

As part of its overall pandemic influenza preparedness efforts, the FDA meets with vaccine manufacturers to guide the efficient establishment of influenza vaccine facilities that comply with agency requirements. The agency promptly reviews applications and manufacturing supplements that could increase both the number of manufacturers and the overall supply of vaccine.

The facility, located in the United States, is owned and operated by Sanofi Pasteur, which manufactures Fluzone Influenza Virus Vaccine. This new facility will greatly increase sanofi pasteur’s production capability.

“This approval represents an important step towards increasing the availability of influenza vaccines,” said Karen Midthun, M.D., the FDA’s acting director of the Center for Biologics Evaluation and Research.

“Increased manufacturing capacity for influenza vaccine is critical to our preparedness for an influenza pandemic,” said Jesse Goodman, M.D., M.P.H., the FDA’s acting chief scientist and deputy commissioner for scientific and medical programs. “This action also enhances the ability to produce and provide vaccines to protect the public from seasonal influenza, still estimated to cause more than 30,000 deaths per year. Thanks to strategic investments by the federal government and proactive efforts and engagement by the FDA and the vaccine industry, our nation’s preparedness has come a long way over the last five years.”

The FDA has interacted with the company throughout the regulatory process to help ensure compliance with applicable requirements.

The bulk manufacturing facility will be used for the production of Fluzone, sanofi pasteur’s egg-based influenza vaccine.

Sanofi Pasteur is located in Swiftwater, Pa.
