Low vaccine effectiveness
in adults 65+ years is
largely
driven by:
Weakened immune system2
due to aging, reducing the body's ability to produce
a
sufficient protective immune response.
Strain mismatch3,4
occurs when circulating influenza strains do not match
the
WHO-selected strains contained in the vaccine.
Most often, it is because of strain mutations from antigenic
drift
or egg adaptation. It can also occur when the prevalent
circulating
influenza strains are different from WHO predictions.
Use an adjuvanted
influenza
vaccine to help address
challenges in
adults 65+ years
An adjuvant is a substance added to a vaccine to boost
the immune
response. Adjuvants have been used in
vaccines for decades.5
Adding MF59® adjuvant to an influenza vaccine
does
more than antigen alone
Conceptualization of the mechanism of action of an

Antigen + MF59 adjuvant
Strengthens immune

Broadens the immune response
by
creating more diverse,

This
may be important if there is a
mismatch
between the influenza
virus strains in the vaccine
and
the circulation influenza strains
designed to strengthen, broaden, and lengthen
the duration of the immune response.7-9

information here.
INDICATION AND USAGE
FLUAD is an inactivated influenza vaccine indicated for active
immunization against influenza disease caused by influenza virus
subtypes A and type B contained in the vaccine.
FLUAD is approved for use in persons 65 years of age and older.
Approval is based on the immune response elicited by
FLUAD.
Data demonstrating a decrease in influenza disease after
vaccination with FLUAD are not available.

FLUAD elicited a strong immune response, meeting noninferiority criteria for all 3 vaccine strains based on predefined thresholds for seroconversion rate differences and geometric mean titer (GMT) ratios, compared to a non-adjuvanted, standard-dose vaccine11,a
Seroconversionb rates:
FLUAD vs non-adjuvanted, standard-dose influenza vaccine at Day 22*
GMTs and GMT ratios:
FLUAD vs non-adjuvanted, standard-dose influenza vaccine at Day 22*
*Differences in seroconversion rate (95% CI).
Study 1 (NCTO1162122) evaluated the safety and immunogenicity of FLUAD in comparison to AGRIFLU. 7082 subjects were randomized and vaccinated with FLUAD (N=3541) or AGRIFLU (N=3541). The primary immunogenicity analyses were conducted on all vaccinated subjects with a blood sample collected at Day 22 (N=3225-3227 [91%] and 3256-3259 (92%) in the FLUAD and AGRIFLU groups, respectively.
aResults obtained following vaccination with influenza vaccine formulated for the 2010-2011 season. bSeroconversion was defined as prevaccination HI titer <10 and postvaccination HI titer ≥40 or at least a 4-fold increase in HI from prevaccination HI titer ≥10. cFLUAD met noninferiority criteria based on seroconversion rate differences if the lower limit of the 95% Cl [FLUAD-AGRIFLU] for each strain was >-10% dFLUAD met noninferiority criteria based on GMT ratios if the lower limit of the 95% Cl (FLUAD-AGRIFLU) for each strain was >0.67,
A/H3N2 is known to be highly virulent, and while it affects the entire population, it is responsible for substantial morbidity and mortality among people over 65 years of age.11
FLUAD has a demonstrated safety profile
FLUAD has a similar safety profile to a non-adjuvanted,
standard-dose influenza vaccine
Most common (≥10%) local and systemic adverse reactions observed within 7 days of vaccination with FLUAD or non-adjuvanted, standard-dose influenza vaccine10,a
aN = number of subjects with safety data. bModerate: pain, tenderness, myalgia, fatigue, headache, arthralgia, chills, nausea, vomiting defined as "some limitation in normal daily activity," diarrhea defined as "4 to 5 stools a day." Severe: pain, tenderness, myalgia, fatigue, headache, arthralgia, chills, nausea, vomiting defined as "unable to perform normal daily activity," diarrhea defined as "6 or more watery stools a day." dpotentially life-threatening (PLT) reaction defined as requiring emergency room visit or hospitalization.
While more frequent injection-site-related events were reported for FLUAD, most were mild to moderate.10
- 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, plunger, and tip cap are not made with natural rubber latex.
Store FLUAD at 2°C to 8°C (36°F to 46°F). Protect from light. Do not freeze. Discard if the vaccine has been frozen. Do not use after expiration date.
