Sanofi Pasteur To Complete Influenza Vaccine Shipments Ahead Of Schedule

SWIFTWATER, Pa., Dec. 1 /PRNewswire/ -- Sanofi pasteur, the vaccines business of the sanofi-aventis Group, will supply 62 million doses of influenza vaccine (Fluzone(R), Influenza Virus Vaccine) to the U.S. market for the 2005-2006 season -- 12 million more doses than the company originally planned to provide. The company shipped more than 58 million doses to customers by the end of November -- six weeks ahead of the original schedule. The remaining 3.5 million doses will be delivered in January to the late season stockpile established by the U.S. Centers for Disease Control and Protection (CDC).

As the most consistent and reliable supplier of injectable influenza vaccine to the U.S. market for many years, sanofi pasteur has made every effort to address public health needs in the most equitable manner possible based on uncertainties arising from market supply disruptions both this year and last year. Sanofi pasteur began shipping influenza vaccine in early August, which was far in advance of other manufacturers and the company is supplying more doses to more providers than ever before. All sanofi pasteur’s confirmed orders were delivered in full this season without reduction.

During the current immunization season, the company estimates it supplied more than 90 percent of the U.S. public sector influenza vaccine market needs, which is significantly more than the company has supplied in prior years. In fact, almost 30 percent of sanofi pasteur’s total influenza vaccine supply was shipped to the public sector. Approximately 30 percent of the company’s supply was shipped to private sector physicians either directly or through distributors, and approximately 10 percent of total doses went to community immunization providers, including the Visiting Nurses Associations. The balance was shipped to hospitals, long-term care facilities, medical centers, academic institutions and corporations.

Once again, the company utilized a split-delivery process that resulted in all customers receiving at least a partial delivery of their orders by the end of October. Although this shipping process is more time consuming and costly for sanofi pasteur, the company has continued the process because it has been recognized as key to facilitating the immunization of priority patients early in the season.

To keep pace with the nation’s growing and changing immunization needs, sanofi pasteur has consistently increased its production and modified distribution plans to provide early shipments to providers that have been identified as most critical in reaching priority high-risk patients designated by the CDC. These providers include long-term care facilities, Veteran’s Administration Hospitals, physicians with pediatric patients and Federal, state, county and city public health departments.

To help address the longer-term needs of the country, sanofi pasteur has begun construction of a new manufacturing facility that will double the company’s capacity to produce influenza vaccine for both routine influenza immunization and in case of an influenza pandemic. The new facility is expected to be completely online for the 2008-2009 influenza season.

Influenza Immunization

While it is optimal to be vaccinated against influenza before disease appears in the community, the CDC indicates that influenza vaccination is still beneficial in December and throughout the influenza season.

Influenza immunization is now recommended for healthy children aged 6 through 23 months, as this age group has been found to be at increased risk for influenza-related hospitalizations. Children younger than 9 years of age receiving influenza vaccine for the first time require two doses, one month apart. The vaccine is also recommended for household contacts and out-of-home caregivers of all children younger than 24 months.

Other groups that have been identified as being at risk for developing serious influenza-related complications include the elderly and adults and children with chronic diseases, such as asthma and diabetes. Influenza vaccination is also recommended for those 50 to 64 years of age, household contacts of at-risk individuals and health-care workers who care for at-risk patients.

All other healthy individuals under age 50 and anyone who wishes to decrease their risk of influenza infection are also encouraged to seek vaccination.

Fluzone vaccine is the only influenza vaccine approved for all populations 6 months and older. In 2004-2005, sanofi pasteur introduced a new Fluzone formulation (trade name: Fluzone(R) Influenza Virus Vaccine, No Preservative) that does not introduce a preservative at any stage in the manufacturing process. It is the first FDA-approved injectable influenza vaccine to be manufactured in this way.

The 2005-2006 influenza vaccine formulation contains the A/New Caledonia/20/99/IVR-116 (H1N1); A/New York/55/2004/X-157 (H3N2) (an A/California/07/2004-like strain); and B/Jiangsu/10/2003 (a B/Shanghai/361/2002-like strain). The three strains for the new influenza vaccine formulation were confirmed by the Food & Drug Administration (FDA), Center for Biologics Evaluation & Research, Vaccines & Related Biological Products Advisory Committee in March 2005. The FDA’s decision corresponds with recommendations made by the World Health Organization in February. Influenza vaccine is reformulated each year to match the strain predicted to circulate in the coming season.

Safety Information

The most common side effects from influenza vaccine are pain and swelling at the vaccination site that can last up to two days. Some people may have mild fever, myalgia (muscle aches), or feel tired for a day or two after receiving the influenza vaccine. Other systemic reactions can occur.

Injectable influenza vaccine is made from killed strains of the viruses predicted to be the main causes of influenza in the coming season. Because the viruses are killed, it is impossible to get influenza from the vaccine.

People who have had previous reactions to the vaccine or people who are allergic to eggs (the viruses used in the vaccine are grown in eggs), egg products, or thimerosal should not receive influenza vaccine. Persons with acute febrile illness usually should not be vaccinated until their symptoms have abated. However, minor illnesses with or without fever do not contraindicate the use of influenza vaccine, particularly among children with mild upper respiratory tract infection or allergic rhinitis.
