Disclosure • I, Kenneth McCall, do not have an interest in selling a technology, program, product, and/or service to CME/CE professionals. • I am a speaker for Merck Vaccines.
Objectives • Discuss the gap between current rates and Healthy People 2020 goals for vaccinations. • Categorize each of the CDC recommended vaccines based upon live/inactivated, route, prep., and storage. • Recognize vaccine-preventable pathogens by common name, classification, and transmission. • Discuss the influenza vaccines for 2012 including the new High-Dose and Intradermal 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.
Outline • Background & Principles of Vaccination • Influenza • Pneumonia • Herpes zoster

Principles of Vaccination* • Passive immunity • Transplacental • Breast milk • Blood products • Active immunity • Infection • Vaccination *Epidemiology and Prevention of Vaccine-Preventable Diseases, 12th Edition
Classification of Vaccines • Live attenuated • Weakened form of the “wild” virus or bacteria • Inactivated • Whole viruses or bacteria • Fractions of viruses or bacteria *Epidemiology and Prevention of Vaccine-Preventable Diseases, 12th Edition
Classification of Vaccines • Live attenuated: • Measles, mumps, rubella, varicella, zoster, intranasal influenza • Inactivated: • hepatitis A, hepatitis B, influenza, pneumonia, diphtheria, tetanus, pertussis, HPV, meningicoccal *Epidemiology and Prevention of Vaccine-Preventable Diseases, 12th Edition
Timing & Spacing of Vaccines • All vaccines can be administered at the same visit as all other vaccines. • Individual vaccines should not be mixed in the same syringe. • When live vaccines (MMR, Varicella, Zoster, and Flumist) are not administered at the same visit, they should be separated by at least 4 weeks. • All other combinations of two inactivated vaccines, or live and inactivated vaccines may be given at any time before or after each other. • Increasing the interval between doses of a multidose vaccine does not diminish the effectiveness of the vaccine. • Decreasing the interval between doses of a multidose vaccine may interfere with antibody response and protection. *Epidemiology and Prevention of Vaccine-Preventable Diseases, 12th Edition
A healthcare provider requests a flu shot, MMR, and varicella vaccine. Which of the following statement about the timing of the vaccines is true? • All three , separate syringes, same day • All three, mix in 1 syringe, same day • Must separate MMR and varicella by 4 wks • Must separate MMR and varicella by 7 days
An 12-year-old girl received the first dose of the HPV vaccine six months ago. The recommend HPV series is a second dose 1-2 mos after first and third dose at least 3 mos after second. What would you recommend to the parent? • The vaccine is no longer indicated • Start the series over and repeat first dose • Give 2nd dose today; 3rd dose in 1 month • Give 2nd dose today; 3rd dose in 3 mos.

Influenza Virus Strains • Influenza A virus • Moderate to severe illness • All age groups • Humans and other animals • Influenza B virus • Milder disease • Primarily affects children • Humans only • Influenza C virus • Rarely reported in humans • No epidemics Seasonal influenza vaccine contains 2 type-A and 1 type-B
Estimated Influenza Vaccination Coverage: 2010-11. †Persons with asthma, diabetes, or heart disease MMWR / June 10, 2011 / Vol. 60 / No. 22
2012-13 ACIP/CDC Recommendations • Routine influenza vaccination continues to be recommended for all persons aged ≥6 months. • While the H1N1 virus is the same as the 2011-2012 recommendation, the recommended influenza H3N2 and B vaccine viruses are different from those recommended for the Northern Hemisphere for the 2011-2012 influenza vaccine. • Persons aged ≥65 years can be administered any of the standard-dose inactivated vaccine or Fluzone High-Dose. • A new intradermally administered TIV preparation, Fluzone Intradermal, was licensed in May 2011 for adults 18 to 65. http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6132a3.htm?s_cid=mm6132a3_e
