ACIP Recommendations for 2015-2016 Influenza
Season
• Advisory Committee on Immunization Practices (ACIP)
Recommendations*:
– All persons aged ≥6 months should receive influenza
vaccine annually
 Either Live Attenuated Influenza Vaccine (LAIV) or

Inactivated Influenza Vaccine, Trivalent, Cell
Culture-Based (ccIIV3)
“Cell-based” refers to how the flu vaccine is made
• Cell-based flu vaccines are developed through a different
manufacturing process
– viruses cultured cells of mammalian origin instead of in
hens’ eggs
• Cell-based flu vaccines are being developed as an
alternative to the egg-based manufacturing process
• Potentially more flexible than the traditional technology,
which relies upon adequate supply of eggs
• http://www.cdc.gov/flu/about/season/index.htm
14
Inactivated Influenza Vaccine, Trivalent, Cell
Culture-Based (ccIIV3)
• A major advantage of cell culture technology includes the potential
for a faster start-up of the vaccine manufacturing process in the event
of a pandemic.
– cells kept frozen and “banked”
– assures an adequate supply of cells is readily available for vaccine
production
– growing the influenza viruses in cell culture for the manufacture
of Flucelvax is not dependent on an egg supply
• Clinical studies demonstrate that Flucelvax is safe and effective for
use in individuals 18 years of age and older
• Typical side effects
– Pain, redness and soreness at the injection site and headache and
fatigue were the most common reactions

those persons for 7 days after getting the nasal spray vaccine).

• Recombinant-based = “egg-free”
• approved for use in the U.S. market in 2013 and that involves using
recombinant technology
• production method does not require an egg-grown vaccine virus and
does not use chicken eggs at all in the production process
• manufacturers isolate a certain protein from a naturally occurring
“wild type" recommended vaccine virus
http://www.cdc.gov/flu/about/season/index.htm
19
Recombinant Influenza Vaccine, Trivalent (RIV3)
• Proteins are then combined with portions of another virus
that grows well in insect cells
• This “recombinant” vaccine virus is then mixed with insect
cells and allowed to replicate
• Flu protein is harvested from cells and purified
• Recombinant flu vaccine is the only 100% egg-free
vaccine on the U.S. market
http://www.cdc.gov/flu/about/season/index.htm
20
Recombinant Influenza Vaccine, Trivalent (RIV3)
• Process can produce vaccine in the shortest amount of
time
– not dependent on an egg supply or limited by the
selection of vaccine viruses that are adapted for
growth in eggs
• Precaution with moderate to severe illness with/without
fever
– History Guillain-Barre syndrome within 6 weeks of
influenza vaccine

Influenza (“The Flu”)
• Influenza is the most frequent cause of death
from a vaccine-preventable illness in the United
States.
• Influenza is highly contagious and attacks the
body’s airways.
• Incubation is from 1-4 days after exposure.
• Signs and Symptoms include
 Fever
 Nasal congestion
 Headache
 Runny Nose
 Dry cough
 Muscle aches
 Sore throat
24
http://www.cdc.gov
Influenza (“The Flu”)
• Each year, 5% - 20% of the U.S.
population develops influenza
– 200,000 hospitalizations
– 36,000 influenza-associated
pulmonary and cardiac deaths
each year
• In outbreaks, as many as 10% to
40% of people are attacked by
the virus
25
http://www.cdc.gov
Influenza is spread by air droplets and hands.
• The influenza virus is spread
from person to person!
• The viruses are spread mainly
by large-particle respiratory
droplets: cough, sneeze, or
talk.
• People infected with influenza
start being contagious one day
prior to showing signs or
symptoms.

Preventing the Flu!
• Vaccination remains the single
best way to prevent the flu!
– Reduce flu illnesses,
– Reduce doctors' visits,
– prevent flu-related
hospitalizations and deaths.
• Vaccination reduces the need
to use antibiotics and over-thecounter medications

Why don’t our patients get the influenza
vaccination?
• Underestimate the Impact of Influenza: “It’s just the flu,
what’s the big deal?”
• Underestimate the prevention power of the vaccination:
“last year, the flu shot didn’t even work!”
• Expense: “I can’t afford it!”
• Underestimate need for annual vaccination: “I got the
shot last year.”
• Concern about the risks of the vaccination: “My friend
took the flu shot and it gave her the flu. Plus it has
mercury in it.” “Vaccines are dangerous!”
• Concern about discomfort: “I hate shots.”
• “I didn’t know I needed it. My doctor didn’t say anything.”
32
Influenza Vaccination Myth Busters!
• Flu vaccine gives you the flu – Busted!
• CDC mandates that everyone has to get a flu shot. It’s the
law – Busted!
• You don’t need to get the flu vaccine every year – Busted!
• Pregnant women should not get the annual flu vaccine –
Busted!
• Children should not get the flu vaccine each year – Busted!
• It’s better to get the flu than to get the flu vaccine – Busted!
• http://www.cdc.gov/flu/about/qa/misconceptions.htm#misconception
33
What can you do in your care setting to break
down barriers to influenza vaccination
• Provide a strong, intentional message recommending
the vaccination.
• Build systematic reminders into clinic workflow
• Standing orders for vaccination of all eligible patients.
• Message the safety of the vaccine while empathically
recognizing the concerns raised by patients
• Message the potential to protect loved ones by
blocking transmission
• Ask about barriers and take time to address
knowledge gaps.
34
Examples from the field of Telligen partners
• "I can respect that decision [to not get the Flu Shot]
for you yourself, but please consider how it is a very
responsible thing to do for those around you; for
instance, you can actually carry the flu, and without
even knowing it, spread it to someone else--and
some others can get hit very hard with it [yes, I do
even share that "tens of thousands die of the flu
every year," but I know that number has been put
into question!].”
35
More examples from the Field of Telligen partners
• “In my experience the more convenient it is for a
patient to receive vaccine the more likely they will get
it. We have used drive thru vaccination clinics, walkin vaccination clinics. Sending reminders and calling
to bring people in helps. “
• Allow the nurse to advocate and provide vaccine
• Standing orders so nurses can administer the vaccine
without a doctor order.
36
Another example from the field of Telligen partners
• “Once patients start to get the vaccine they will get it
in subsequent years because they note how healthy
they remain during the winter. The problem is how to
make a person a ‘believer’ initially. Testimonials from
peers helps.”
37
Clean Hands Save Lives!
• Hand-washing prevents illness and the
spread of germs to others.
• Live Influenza virus can transfer from
nonporous surfaces to hands for 24 h
and from tissues to hands for 15 min.
• Hand-washing reduces the total rate of
respiratory illnesses
• Hand sanitation using 95% ethanol, kills
influenza viruses on the hands.
Clinical Infectious Diseases 2003; 37:1094–1101
38
http://www.cdc.gov
Knowledge Sharing
• Everyone 6 months of age and older should be vaccinated if
they have no contraindications (if contraindicated speak with
healthcare provider about alternatives)
• Get vaccinated as soon as vaccine available
• It is possible to get a respiratory virus other than flu during
flu season- similar symptoms
• Influenza virus spread through droplets
• Influenza virus can survive on surfaces between 2 and 8
hours
• Persons can be contagious 1 day before symptoms appear
and up to 7 days after
39
What can we all do?
• Get influenza vaccine as soon as possible
• Avoid contact with sick people, limit your contact with others
when you are sick
• Wash your hands frequently
• Cover your nose and mouth with a tissue when you cough or
sneeze, then immediately wash your hands
• Be aware of touching your eyes, nose or mouth, avoid
spreading germs
• Clean commonly touched or exposed surfaces
often(workspaces, door knobs, faucets, handles, etc.)
• Use alcohol based hand rubs

Summary
• Getting the influenza vaccine decreases likelihood of
getting the flu and, although not perfect, offers the
best opportunity for protection against influenza.
• There are a number of reasons that people choose
not to receive the seasonal influenza vaccination.
A variety of strategies can be used to successfully
overcome the barriers and optimize use of the
influenza vaccine to fight influenza.
