CDC Advisory Committee Includes FLUAD® QUADRIVALENT as a Preferentially Recommended Influenza Vaccine for Adults 65 and Older

• ACIP recommends adults 65 years of age and older receive an enhanced flu vaccine, such as FLUAD^® QUADRIVALENT (Influenza Vaccine, Adjuvanted), to help protect against four strains of seasonal influenza annually
• The committee reviewed randomized studies and real-world data spanning multiple seasons and numerous flu-related outcomes in support of FLUAD QUADRIVALENT to inform their recommendation

SUMMIT, N.J., June 22, 2022 /PRNewswire/ -- Seqirus, a global leader in influenza prevention and a business of CSL Limited (ASX:CSL), today announced that the U.S. Centers for Disease Control and Prevention's (CDC) Advisory Committee on Immunization Practices (ACIP) has included FLUAD^® QUADRIVALENT as a preferentially recommended seasonal influenza vaccine for adults 65 years of age and older. The preferential recommendation for FLUAD QUADRIVALENT for all adults 65 years and older is based on the clinical benefits compared to standard egg-based influenza vaccines, as demonstrated within the total body of evidence.¹

"It is critical that we do everything we can to protect vulnerable populations like older adults against influenza," said Gregg Sylvester, MD, Chief Health Officer, Seqirus. "Today's recommendation is evidence of the ACIP's commitment to providing clear, evidence-backed guidance to protect public health. We are proud to offer one of the enhanced flu vaccines that was preferentially recommended by the ACIP for adults 65 years and above in the U.S."

Immunosenescence, the age-associated decline of the immune system, may result in a reduced immune response to antigens in the vaccine.² FLUAD QUADRIVALENT is specifically created for adults 65 years and older using Seqirus' MF59^® adjuvant, designed to help strengthen, broaden and lengthen the immune response to influenza vaccination.^2,3,4,5 Approximately 80 percent of influenza-related deaths and 50 to 70 percent of influenza-related hospitalizations occur among adults 65 years and older, according to the CDC.⁶

FLUAD is proven to be safe and effective and has an extensive clinical legacy, with more than 225 million doses distributed and licensure in over 30 countries since it was first approved in 1997.^7,8

More than 20 years of real-world evidence supports the clinical value of FLUAD in reducing influenza-related clinical outcomes in adults 65 years and older across different influenza seasons with different study designs, clinical outcomes, and study limitations.⁴ Seqirus will offer this enhanced seasonal vaccine option for pharmacy partners, healthcare providers and their patients during the upcoming 2022/23 Northern Hemisphere influenza season in the U.S. to better help protect this population from influenza and severe influenza-related outcomes.

"This preferential recommendation sends a clear message that FLUAD QUADRIVALENT is an important treatment option for people 65 years of age and older," said Dave Ross, Vice President, North America Commercial Operations, Seqirus. "A preferential recommendation for adults 65 and older helps to provide guidance to both healthcare providers and patients on the standard of care for this at-risk population."

Seqirus' differentiated portfolio of seasonal influenza vaccines for the U.S. also includes FLUCELVAX^® QUADRIVALENT (Influenza Vaccine), the first and only cell-based quadrivalent influenza vaccine for people six months of age and older in the U.S.⁹ Cell-based influenza vaccines are designed to produce an exact match to the World Health Organization (WHO)-selected influenza virus strains by avoiding egg-adapted changes and therefore have the potential to lead to greater vaccine effectiveness.¹⁰

According to the ACIP, if one preferentially recommended influenza vaccine is not available to adults 65 years and older, then any other age-appropriate influenza vaccine should be used.²

About Seasonal Influenza
Influenza is a common, contagious seasonal respiratory disease that may cause severe illness and life-threatening complications in some people.¹¹ Influenza can lead to clinical symptoms varying from mild to moderate respiratory illness to severe complications, hospitalization and in some cases, death.¹¹ Because transmission of influenza viruses to others may occur one day before symptoms develop and up to 5 to 7 days after becoming sick, the disease can be easily transmitted to others.¹¹ Estimates from the Centers for Disease Control and Prevention (CDC) report that during the 2019/20 influenza season, there were an estimated 405,000 influenza-related hospitalizations in the U.S.¹² The CDC recommends annual vaccination for individuals aged 6 months and older, who do not have any contraindications.¹³ Since it takes about two weeks after vaccination for antibodies to develop in the body that help protect against influenza virus infection, it is recommended that people get vaccinated before influenza begins spreading in their community.¹³ The CDC recommends that people get vaccinated by the end of October.¹³
