What makes FLUAD different? It's adjuvanted.1
FLUAD is the first FDA-approved seasonal influenza vaccine made with MF59®, an immune-enhancing adjuvant derived from squalene: a naturally occurring substance found in humans, plants, and animals, which is proven to help provide a strong immune response to the influenza for adults 65 and older.1,2

FLUAD® is an influenza vaccine that is clinically proven to generate a strong immune response in adults 65 and older. FLUAD is the first FDA-approved seasonal influenza vaccine in the United States. made with an immune-enhancing adjuvant, MF59®, for people 65 and older. MF59® is derived from squalene, a naturally occurring substance found in humans, plants and animals. Studies suggest MF59® recruits immune cells to the site of injections and enhances their uptake of antigen.1,2,4
The CDC recommends FLUAD® as an acceptable option to other vaccines licensed (or indicated) for people 65 years of age and older for immunization against influenza.5
The CDC has not made a preferential recommendation for any influenza vaccine formulation directed toward this age group.2
In a large pivotal trialb (N=7082), FLUAD elicited a strong immune response in adults 65 and older1,c

bStudy 1 (NCT01162122) was a multicenter, observer-blind, randomized, controlled study that evaluated the safety and immunogenicity of FLUAD in comparison to AGRIFLU, a US-licensed nonadjuvanted trivalent influenza vaccine. A total of 7082 subjects aged 65 years and older were randomized and vaccinated with FLUAD (n=3541) or AGRIFLU (n = 3541). The primary immunogenicity analysis was performed on all vaccinated subjects who had a blood sample collected at Day 22 (n=3225-3227 [91%] and 3256-3259 [92%] in the FLUAD and AGRIFLU groups, respectively). A determination of noninferiority was made on the basis of predefined thresholds for seroconversion rate differences and GMT ratios. cResults obtained following vaccination with influenza vaccine formulated for the 2010 to 2011 season. dSeroconversion was defined as prevaccination hemagglutination inhibition (HI) titer <10 and postvaccination HI titer ≥40 or at least a 4-fold increase in HI from prevaccination HI titer ≥10. 3n = 3225-3227, the number of vaccinated participants with available data for the immunologic endpoint listed. fn = 3256-3259, the number of vaccinated participants with available data for the immunologic endpoint listed. gFLUAD met noninferiority criteria based on seroconversion rate differences if the lower limit of the 95% CI [FLUAD : AGRIFLU] for each strain was >-10%. hFLUAD met noninferiority criteria based on GMT ratios if the lower limit of the 95% CI [FLUAD: AGRIFLU] for each strain was >0.67.
A demonstrated safety profilea
In the pivotal trial, the most common (≥10%) adverse reactions in subjects receiving FLUAD were1:
Injection Site Pain (25%)
While higher rates of solicited adverse reactions were noted with FLUAD, they were typically mild to moderate1
Thea safety analysis included subjects (n = 3545 FLUAD; n = 3537 AGRIFLU) from Study 1 who completed a symptom diary card for 7 days following vaccination.
- For intramuscular injection only
- FLUAD is supplied as a package of ten, 0.5-mL prefilled needleless syringes
- Administer FLUAD as a single 0.5-mL intramuscular injection in adults 65 years of age and older
- Each 0.5-mL dose of FLUAD is preservative free. The syringe, syringe plunger stopper, and tip cap are not made with natural rubber latex.
