Seqirus Receives FDA Approval for FLUAD® QUADRIVALENT (Influenza Vaccine, Adjuvanted) for Adults 65 Years and Older

Quadrivalent formulation of the first-and-only adjuvanted seasonal influenza vaccine for older adults (65+ years) receives FDA approval1

  • Designed with MF59® adjuvant to help strengthen, broaden and lengthen the body’s immune response against the influenza strains contained in the vaccine[1],[2],[3],[4]

Summit, NJ – February 24, 2020

Seqirus announced today that the U.S. Food and Drug Administration (FDA) has approved the first adjuvanted quadrivalent influenza vaccine, FLUAD® QUADRIVALENT (Influenza Vaccine, Adjuvanted), to help protect adults 65 years and older against seasonal influenza.1

Adults 65 years and older are at high risk for influenza-related complications each season and it is important to have influenza vaccines to help protect this vulnerable population,” said Anjana Narain, Executive Vice President and General Manager at Seqirus. As part of our leading role on the front line of influenza prevention, we are pleased to offer FLUAD QUADRIVALENT as another seasonal vaccine option for healthcare providers and their patients in the fight against influenza.”

In the U.S., influenza impacts adults 65 years and older with higher hospitalization and death rates compared to young, healthy adults.[5] During the 2017/18 influenza season, 70 percent of influenza-related hospitalizations and 90 percent of influenza-related deaths occurred in this age group.[6] Influenza vaccine effectiveness also tends to be lower in this population due to age-related immune decline, which reduces the body’s ability to produce a sufficient, protective immune response to the vaccine.[7]

FLUAD QUADRIVELENT (aQIV) utilizes the same MF59® adjuvant technology as FLUAD® (aTIV),[8] designed to create a strong, broad and durable immune response.1,2,3,4 FLUAD QUADRIVELENT includes an additional strain to FLUAD, which has an extensive clinical legacy, with 114+ million doses distributed and licensure in 29 countries since it was first approved in 1997.[9],[10]

“The burden of seasonal influenza among adults 65 and older, remains an important public health concern,” said Gregg Sylvester, MD, Chief Medical Officer at Seqirus. “At Seqirus, we’re committed to developing advanced technologies and vaccines designed to address unmet needs, especially in vulnerable populations, such as adults 65 years and older.”

According to the Centers for Disease Control and Prevention (CDC), everyone who is six months and older should receive an annual flu shot, but it is particularly important for those 65 years and older who are at risk of developing serious complications from influenza.[11]

FLUAD QUADRIVELENT and FLUAD are the first-and-only adjuvanted seasonal influenza vaccines approved in the U.S. for adults 65 years and older.1,8,[12]

About Seasonal Influenza 

Influenza is a common, highly contagious infectious disease that can cause severe illness and life-threatening complications in many people.[13] To reduce the risk of more serious outcomes, such as hospitalization and death, resulting from influenza, the CDC recommends annual vaccination for all individuals aged 6 months and older.[14]  Because transmission 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.13 Influenza can lead to clinical symptoms varying from mild to moderate respiratory illness to severe complications, hospitalization and in some cases, death.13 Preliminary estimates from the CDC report that up to 647,000 people in the United States were hospitalized due to influenza-related complications during the 2018/19 influenza season.[15] Since it takes about two weeks after vaccination for antibodies to develop in the body that protect against influenza virus infection, it is best that people get vaccinated to help protect them before influenza begins spreading in their community.14
