Health Indicator Report of Immunization - Influenza, Adults
Influenza, or flu, is an acute viral infection involving the respiratory tract that can occur in epidemics or pandemics. Influenza can cause a person, especially older persons, to be more susceptible to bacterial pneumonia. It was estimated that in the 2019-2020 flu season, 38 million flu illnesses occurred in the U.S. resulting in 400,000 hospitalizations and 22,000 deaths.^1^ The annual direct medical costs (hospitalization, doctors office visits, medications, etc.) for influenza in adults are estimated at $8.7 billion including $4.5 billion for adult hospitalizations resulting from influenza-attributable illness. Influenza is also responsible for substantial indirect costs ($6.2 billion annually), mainly from lost productivity.^2^ __References__ #Centers for Disease Control and Prevention (CDC).

Influenza Vaccination in the Past 12 Months, Utah and U.S. Adults Aged 65+, 2001-2019
NotesIn 2011, the BRFSS changed its methodology from a landline only sample and weighting based on post-stratification to a landline/cell phone sample and raking as the weighting methodology. The data for 2011 and later on this graph are based on the new methodology (landline/cell phone sample; raking). Due to changes in both sampling and the question format, data for 2011 and later should be interpreted with caution compared to previous years. U.S. data are the average for all states and the District of Columbia; they do not include the U.S. territories. These rates are crude rates, not age-adjusted, given that the Healthy People 2020 Objective is based on crude rates.

Data Interpretation IssuesAdult data for Utah and U.S. is also available from the FluVaxView Influenza Vaccination Coverage web page, which is estimated annually by CDC utilizing data from several nationally representative surveys. These surveys include the National Health Interview Survey (NHIS), the Behavioral Risk Factor Surveillance System (BRFSS), the National Immunization Survey (NIS), and in 2009-10, the National 2009 H1N1 Flu Survey (NHFS). For the 2010-11 influenza season, additional assessment systems were developed to provide timely coverage estimates for selected populations. These include: rapid household telephone surveys and cell phones conducted nationally and in 20 selected local areas, internet panel surveys of pregnant women and health care workers, and use of third-party medical claims data. Beginning in 2011, BRFSS data include both landline and cell phone respondent data along with a new weighting methodology called iterative proportional fitting, or raking. This methodology utilizes additional demographic information (such as education, race, and marital status) in the weighting procedure. Both of these methodology changes were implemented to account for an increased number of U.S. households without landline phones and an under-representation of certain demographic groups that were not well-represented in the sample. More details about these changes can be found at: [https://ibis.health.utah.gov/pdf/opha/resource/brfss/RakingImpact2011.pdf]. The survey question for this measure changed in 2011 to "During the past 12 months, have you had either a seasonal flu shot or a flu vaccine that was sprayed into your nose?". In previous years the question was "A flu shot is an influenza vaccine injected in your arm. During the past 12 months, have you had a seasonal flu shot?".

Healthy People Objective IID-12.12:Increase the percentage of adults aged 18 and older who are vaccinated annually against seasonal influenza
U.S. Target: 70.0 percent
Other ObjectivesUtah's 42 Community Health Indicators[[br]] CSTE Chronic Disease Indicators
How Are We Doing?The percentage of Utahns aged 65+ who received a flu vaccine is measured by the Behavioral Risk Factor Surveillance System (BRFSS) survey, and was found to be 63.9% in 2019 as compared to 52.0% in 2018. There was a decrease in coverage rates from 2007-2010 using the old BRFSS methodology and we saw a continuation of this decreased trend in 2011 and 2012 using the new methodology that was implemented in 2011. Using the new methodology, there was an increase in coverage rates from 2013-2015. Between 2015-2019 the rate fluctuated between 63.9% and 52.0%. The data can fluctuate year to year, and it will be useful to look at the data in the future to see which way the trend will go.
How Do We Compare With the U.S.?In Utah, 63.9% of adults aged 65+ surveyed on the Behavioral Risk Factor Surveillance System (BRFSS) in 2019 reported receiving a flu shot in the previous 12 months. Nationwide for the same age group, the rate was 63.8%.
What Is Being Done?The UDOH Immunization Program and Office of Epidemiology educate health care providers, clinic staff, and the public about flu vaccination. ==Who Should Get Influenza Vaccine?== Everyone 6 months of age and older should get an flu vaccine every season with rare exception. For the 2019-2020 season, the Advisory Committee on Immunization Practices (ACIP) recommends annual influenza vaccination for everyone six months and older with any licensed, appropriate influenza vaccine with no preference expressed for any one vaccine over another. Some vaccines are not recommended in some situations and health conditions, and some people should not receive influenza vaccines at all (though this is uncommon). ===The Influenza (Flu) Shot=== ====People who can get the flu shot:==== *Different flu shots are approved for people of different ages. Everyone should get a vaccine that is appropriate for their age. *There are inactivated influenza vaccines that are approved for people as young as six months of age. *Some vaccines are only approved for adults. *Flu shots are recommended for pregnant women and people with chronic health conditions. [[br]] ====People who SHOULD NOT get the flu shot:==== *Children younger than six months of age are too young to get the flu shot. *People with severe, life-threatening allergies to flu vaccine or any ingredient in the vaccine. This might include gelatin, antibiotics, or other ingredients. [[br]] ====People who should talk to their doctor before getting the flu shot:==== If you have one of the following conditions, talk with your healthcare provider: *If you have an allergy to eggs or any of the ingredients in the vaccine. Talk to your doctor about your allergy. *If you ever had Guillain-Barr Syndrome (a severe paralyzing illness, also called GBS). Some people with a history of GBS should not get this vaccine. Talk to your doctor about your GBS history. *If you are not feeling well, talk to your doctor about your symptoms. [[br]] ===Nasal Spray Flu Vaccine=== ====People who can get the nasal spray flu vaccine:==== *The nasal spray vaccine is approved for use in people 2 years through 49 years of age. It is an option for healthy, non-pregnant people in this age group. [[br]] ====People who SHOULD NOT get the nasal spray vaccine:==== *Children younger than two years *Adults 50 years and older *Pregnant women *People with severe, life-threatening allergies to flu vaccine or any ingredient in the vaccine *Children 2 years through 17 years of age who are receiving aspirin- or salicylate- containing medications *People who are immunocompromised *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 influenza antiviral drugs within the previous 48 hours *People who care for severely immunocompromised persons who require a protected environment *People who have taken influenza antiviral drugs in the previous 48 hours [[br]] ====People who should talk to their healthcare provider:==== If you have one of the following conditions, talk with your healthcare provider. He or she can help decide whether vaccination is right for you, and then select the best vaccine for you situation: *People with asthma aged 5 years and older *People with other underlying medical conditions that can put them at high risk of developing serious flu complications. These include conditions such as chronic lung diseases, heart disease (except isolated hypertension), kidney disease, liver disorders, neurologic and neuromuscular disorders, blood disorders, or metabolic disorders (such as diabetes) *People with moderate or severe acute illness with or without fever *People with Guillain-Barr Syndrome within 6 weeks following a previous dose of influenza vaccine [[br]] __Reference__[[br]] Centers for Disease Control and Prevention (CDC).
