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(IIV)

– Children 2 to 8 yrs. may receive either LAIV or IIV– If child (ages 2 to 6) has not received vaccine in past, then give 2 doses

(each dose ≥ 4 weeks apart) 8 years is the upper age limit for receipt of 2 doses of influenza

vaccine in a previously unvaccinated child

*For complete recommendations visit:

5


• LAIV should not be used in the following populations: – Persons aged <2 years or >49 years– Persons with contraindications listed in the package insert:

Children aged 2 through 17 years who are receiving aspirin or aspirin-containing products;

Persons who have experienced severe allergic reactions to the vaccine or any of its components, or to a previous dose of any influenza vaccine

– Pregnant women– Immunocompromised persons– Persons with a history of egg allergy

http://www.cdc.gov/media/releases/2015/s0226-acip.html

6


• LAIV continued: – Children aged 2 through 4 years who have asthma history of

wheezing in the past 12 months– Persons who have taken influenza antiviral medications within the

previous 48 hours– Other underlying medical conditions that might predispose them to

complications after wild-type influenza infection– Persons who care for severely immunosuppressed persons who

require a protective environment Should avoid contact with such persons for 7 days after receipt

“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

15


• 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

component of the vaccine or to a previous dose of any influenza vaccine

– Those with egg allergies


18

FluMist® Quadrivalent Vaccine

• Not recommended for:– Children or adolescents (2 years through 17 years of age) on long-term

aspirin treatment.– Pregnant women– People with weakened immune systems (immunosuppression)– Children 2 years through 4 years who have asthma or who have had a

history of wheezing in the past 12 months.– People who have taken antiviral medications within the previous 48 hours.– People who care for severely immunocompromised persons who require

a protective environment (or otherwise avoid contact with those persons for 7 days after getting the nasal spray vaccine).


19

Recombinant Influenza Vaccine, Trivalent (RIV3)

• 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


Trade Name Presentation Age Indications

Route

FluBlok® 0.5mL single-dose vial

≥18 yrs. IM

20


• 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


21


• 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

http://www.cdc.gov

Fever Nasal congestion

Headache Runny Nose

Dry cough Muscle aches

Sore throat

25

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 http://www.cdc.gov

26

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.

http://blogs.cdc.gov/niosh-science-blog/2013/01/15/catchingtheflu/

27

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-the-counter medications

Vaccination Rates

Flu Seasons: 2013-2014; 2014-15

32

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.”

33

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

34

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.

35

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!].”

36

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, walk-in 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.

37

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.”

38

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

39

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

40

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

Questions/Comments for presenters?

Q & A

42

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.
