- CSL Seqirus is the only manufacturer to offer a differentiated influenza vaccine for all eligible people aged six months and older in the United States.
- Centers for Disease Control and Prevention (CDC) trend findings indicate a significant decline in influenza vaccination rates, which poses a serious risk to public health infrastructure and underscores the importance of receiving an annual influenza vaccination.1,2

SUMMIT, N.J., July 9, 2024 /PRNewswire/ -- CSL Seqirus, a business of CSL (ASX: CSL), today announced that it has commenced shipping its differentiated portfolio of influenza vaccines. This year, the company’s influenza vaccines are being produced as trivalent influenza vaccine (TIV) formulations, in compliance with the U.S. Food and Drug Administration’s (FDA) directive to remove the B/Yamagata strain.4
“We are proud to support healthcare providers in their efforts to vaccinate their patients and communities to help turn around concerning declines in seasonal influenza vaccination rates,” said Stefan Merlo, Vice President of Commercial Operations, North America, CSL Seqirus. “We are a committed partner in public health and are doing our part to educate, inform, and meet the evolving needs of the public, ensure customers are prepared for the upcoming flu season, and help reverse this downward trend to restore vaccination rates.”
This season, the 2024/25 influenza vaccine portfolio for CSL Seqirus, the only manufacturer to offer a differentiated influenza vaccine option approved for use in people aged six months and older, includes:
- FLUCELVAX® (Influenza Vaccine), the first and only cell-based influenza vaccine indicated for use in people six months and older.5
- FLUAD® (Influenza Vaccine, Adjuvanted), the first and only adjuvanted seasonal influenza vaccine for adults 65 and older, which is preferentially recommended by the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) over standard-dose influenza vaccines.6,7
- FLUAD contains an MF59® adjuvant that is designed to strengthen, broaden, and lengthen the immune response when added to an influenza vaccine.6,8,9
- AFLURIA® (Influenza Vaccine), an egg-based, influenza vaccine approved for use in eligible people six months of age and older.10
The impact of declining vaccination rates poses a serious risk to public health infrastructure, with preliminary estimates from the CDC reporting an increase in influenza-related hospitalizations and deaths last season, in comparison to seasons prior, as well as an overburdened healthcare system.11,12 Across all age cohorts, vaccination rates experienced double-digit percentage declines over the past three flu seasons according to internal calculations based on influenza tracking data.13 This includes a notable 22% drop among children aged 6 months to 18 years and a 14% decrease in adults over 65, a group that typically maintains stable immunization rates.13
Additionally, the public health burden of influenza outpaces other respiratory illness.11,14,15 During the 2023/24 flu season, influenza accounted for nearly half of hospitalizations attributed to infectious diseases including influenza, COVID and respiratory syncytial virus (RSV) combined and over half of total deaths.11,14,15 This data underscores the importance of the CDC’s recommendation that all eligible people aged six months and older receive an annual influenza vaccination as an essential measure to help prevent influenza and its complications.2 This is especially important for those at an increased risk of severe influenza-related complications, such as older adults, pregnant people, and children under five years old.3
“Influenza continues to pose a significant threat, as evidenced by recent flu seasons,” said Dr. Gregg Sylvester, Chief Health Officer, CSL Seqirus. “As we begin distributing influenza vaccines to healthcare providers throughout the U.S., it is imperative that we work to maintain high vaccination rates this season to help reduce the burden of influenza-related illnesses and the risk of severe outcomes.”

About Seasonal Influenza
Influenza is a common, contagious seasonal respiratory disease that may cause severe illness and life-threatening complications in some people.16 Influenza can lead to clinical symptoms varying from mild to moderate respiratory illness to severe complications, hospitalization and in some cases, death.16 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.16 Preliminary estimates from the Centers for Disease Control and Prevention (CDC) report that during the 2023/24 influenza season, there were an estimated 390,000-810,000 influenza-related hospitalizations in the U.S.11 The CDC recommends annual vaccination for people aged six months and older, who do not have any contraindications.2 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.2 The CDC recommends that for most people who need only 1 dose of flu vaccine, vaccination should ideally happen in September or October.2About CSL Seqirus
