FDA Approves 1st Adjuvanted Quadrivalent Flu Shot For Seniors
Fluad Quadrivalent vaccine helps protect adults 65 years and older against seasonal influenza
The U.S. Food and Drug Administration (FDA) has approved the first and only adjuvanted quadrivalent influenza vaccine, Fluad® Quadrivalent to help protect adults 65 years and older against seasonal influenza.
This is good news since, during the 2017/18 influenza season, 70 percent of influenza-related hospitalizations and 90 percent of influenza-related deaths occurred in this age group.
As of February 15, 2020, the highest rate of hospitalization in the USA was reported among adults aged ≥65, at 116.7 cumulative rate per 100,000 population.
The FDA notified Seqirus, Inc. on February 21, 2020, it had approved the request received on January 22, 2019, to include a quadrivalent formulation (Fluad Quadrivalent) for active immunization of persons 65 years of age and older against influenza disease caused by seasonal influenza virus subtypes A and types B contained in the vaccine.
Fluad Quadrivalent (aQIV) utilizes the same MF59® adjuvant technology as FLUAD® (aTIV), designed to create a strong, broad and durable immune response.
It also 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.
"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, in a related press release.
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.
According to the Centers for Disease Control and Prevention (CDC), everyone who is 6 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.
And, 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.
Influenza can lead to clinical symptoms varying from mild to moderate respiratory illness to severe complications, hospitalization and in some cases, death.
Since it takes about two weeks after vaccination for antibodies to develop in the body that protects against influenza virus infection, it is best that people get vaccinated to help protect them before influenza begins spreading in their community.
