2 Objectives Discuss the gap between current rates and Healthy People 2020 goals for vaccinations. Categorize each of the CDC recommended flu vaccines based upon live/inactivated, route, prep., and storage. Discuss the influenza vaccines for 2014 including the new quadrivalent and mammalian cell vaccines. Identify vaccine contraindications and recommend vaccines based upon age and medical history. Apply ACIP recommendations and FDA approved indications for the CDC recommended vaccines.

10 Vaccines that might be indicated for adults based on medical and other indications

11 2014 Influenza Vaccination Recommendations Annual vaccination against influenza is recommended for all persons aged 6 months or older. Adults aged 18 to 49 years can receive the recombinant or mammalian vaccine. Healthy, nonpregnant persons aged 2 to 49 years without high-risk medical conditions can receive either intranasal, live vaccine or inactivated vaccine. Health care personnel who care for severely immunocompromised persons should receive inactivated vaccine. Adults 18 to 64 years can receive either the intramuscular or intraderm. Adults 65+ years can receive either the standard-dose or the high-dose.

16 Influenza Surveillance CDC has antigenically characterized 2,110 influenza viruses Influenza A 2009 H1N1 [1,657]: 99.9% of the 2009 H1N1 viruses tested were characterized as A/California/7/2009-like, the influenza A (H1N1) component of the Northern Hemisphere influenza vaccine. Influenza A (H3N2) [269]: 98.1% of the influenza A (H3N2) viruses tested have been characterized as A/Texas/50/2012-like, the influenza A (H3N2) component of the Northern Hemisphere influenza vaccine. Influenza B [184]: 124 (67%) of the 184influenza B viruses tested belong to B/Yamagata/16/88-lineage and the remaining 60 (33%) influenza B viruses tested belong to B/Victoria/02/87 lineage. Yamagata Lineage [124]: 124 influenza B/Yamagata-lineage viruses were characterized as B/ Massachusetts/2/1012-like, which is included as an influenza B component of the Northern Hemisphere trivalent and quadrivalent influenza vaccines. Victoria Lineage [60]: 60 influenza B/Victoria-lineage viruses were characterized as B/Brisbane/60/2008-like, which is included as an influenza B component of the Northern Hemisphere quadrivalent influenza vaccine.
