  2. Big 5 Itinerary: ACIP Adult Immunization Schedule

  3. Adult Immunization: The Inside StoryVaccines for Adults (price per dose) *means company websitehttp://www.cdc.gov/vaccines/programs/vfc/awardees/vaccine-management/price-list/index.html Meningococcal ACWY ($71-75) B*: Bexsero$160 (need 2) Trumenba$135 (need 3) MMR (live) ($59)- need 2 Pneumococcal PPSV 23- ($72) PCV 13-($152) Shingles ($187) Td/ Tdap ($24 / $37) Varicella ($100) need 2 • Flu- • Inactivated shot ($12-19) • Egg-free FluBlok ($32) • Nasal vaccine (live) ($24) • Intradermal* ($17.50) • High dose* ($30) • Hep A ($63-65)- need 2 • Hep B ($52-59)- need 3 • HPV- Series 3 doses • HPV2, HPV4, HPV9* • $128 / $147 / $163 • Hib* haemophilusinfluenza type b ($27)

  4. ACIP – Evidence Based Approach • October 2010, adopted an evidence-based process -GRADE (Grading of Recommendations, Assessment, Development and Evaluation). • evaluates • quality of evidence • benefits/harms • values and preferences of affected populations • economic impact

  5. Grading of Recommendations, Assessment, Development and Evaluation (GRADE)Types of Recommendations • Category A recommendation • made for all persons in an age- or risk-factor-based group. • Category B recommendation • made for individual clinical decision making. • Evidence tables • summarize the benefits and harms and the strengths and limitations of the body of evidence.

  6. Vaccine Information Statements (VIS)http://www.cdc.gov/vaccines/pubs/vis/default.htm

  7. ACIP coverage clout under new ACA plans • New health plans will be required to cover new ACIP recommendations made after September 2009 without cost-sharing in the next plan year that occurs one year after the date of the recommendation. • Does not apply to Medicare.

  8. FDA versus ACIP • ACIP recommendations are not always consistent with FDA licensing. • FDA(Food and Drug Administration) licensing • ACIP (Advisory Committee on Immunization Practices) • ACA: ACIP recommendation coverage clout • New health plans: ACA requirement coverage without cost sharing one year after recommendation is made. • Does not apply to Medicare.

  9. FDA Licensing Process • IND: Investigational New Drug Application • Includes protocol for human studies • Preclinical licensure trials: • Phase 1 studies (small study) • Phase 2 Studies (larger study- hundreds of patients) • Phase 3 Studies (vaccine effectiveness and safety- thousands of patients) • BLA: Biologics License Application request • Accelerated Approval Pathway (fast track) • based on early evidence of effectiveness • May not satisfy comprehensive ACIP GRADE evidence assessment

  10. The Big 5: Flu FLU FACTShttp://www.cdc.gov/flu/about/qa/disease.htm On average each year: • Up to 20% of US get flu • More than 200,000 hospitalized • Up to 49,000 die

  11. FLU: Everyone 6 months & older needs flu vax every year

  12. Flu Prevention: Which flu vaccine to give? • Inactivated flu shot • High dose • Intradermal • Needleless • Nasal flu vaccine

  13. Flu Vaccination 2015-2016 : Standard Shot (IIV3 and IIV 4) • IIV 3: Trivalent vaccines will contain: • A/California/7/2009 (H1N1)pdm09-like virus; (same as 2014-2015) • A/Switzerland/9715293/2013 (H3N2)-like virus; (NEW) • B/Phuket/3073/2013-like virus. (NEW) • IIV 4: Quadrivalent vaccines:the above + • B/Brisbane/60/2008-like virus(same as 2014-2015)

  14. High dose flu shot (for Seniors): Fluzone High Dose • For seniors 65 and older • Inactivated vaccine • Contains four times more hemaglutinin per dose than standard flu vaccine • Designed to improve immune response. • Downsides • More injection site reactions • Cost (almost double the price) • Covered by Medicare B : CPT code 90662, admin code 90471

  15. Intradermal Flu Vaccine:Fluzone Intradermal: age 18-64

  16. Needle Free TechnologyPharmaJetStratis • NoFlu “No Needles” Flu vaccine • Delivers an injectable liquid vaccine-- narrow, precise fluid stream injection, penetrates the skin in about 1/10 second • Spring-operated, requiring no external power source • Sterile, single-use, auto-disabling syringe • Age 18-64

  17. Nasal Flu Vaccine (LAIV) age 2-49 & healthy • Live attenuated nasal influenza vaccine • Option for healthy non-pregnant adults < 50. • Not for pregnant women (different from package insert) Pregnant women : high risk for influenza complications but should only receive inactivated vaccine.

  18. Mild (hives only) Egg Allergy • Can get the inactivated flu shot.  • That’s what’s been studied.  • They can’t get the nasal flu vaccine. •  Person giving the vaccine should • Be familiar with  “egg allergy” • Observe patient for at least 30 minutes

  19. Recombinant Influenza Vaccine (RIV 3) • Trivalent • Brand name – FluBlok • For 18 and older • Totally egg free • Can be given to age appropriate with egg allergy of any severity

  20. Babies and FLU • Babies under six months old: • too young to get flu shot • too young for anti-virals • little ones are most at risk • more likely to be hospitalized • more likely to die if they get the flu • Family members and care givers of babies need flu vaccination.

  21. Tdap : A Family Affair (tetanus/diptheria/pertussis) • Pertussis = whooping cough • Last 10 years- surge in pertussis related deaths in infants • Cocoon babies in circle of protection • Household members are to blame for up to 83% of transmission

  22. Who needs Tdap? • Adolescents need Tdap booster • Unvaccinated dads need one time Tdap booster • Grandparents need one time Tdap booster • Pregnant women need Tdap in each pregnancy (in late 3rd trimester between 27-36 weeks)

  23. February 2012 ACIPTdap for Adults : Universal Recs • Adults age 65 & + had higher rates of hospitalization than those age 19-64 • Expand Tdap booster to ALL adults age 65 and older – not just those with close contact with infants • Universal Tdap booster for ALL adults!

  24. ACIP guidance statement MMWR , June 29, 2012 / 61(25);468-470 http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6125a4.htm • Currently, only a single booster dose of Tdap is recommended October 2012: Pregnant women need Tdap in EACH pregnancy. (Multiple Tdap boosters is off -label use )

  25. The Big 5: Hep B Hep B FACTS • Chronic Infection • 800,000 to 1.4 million people suffer from it • 3000 cases of acute Hepatitis B each year • Can lead to liver cancer

  26. The Big 5: Hepatitis B • Transmitted by exposure to infected blood or body fluid • Who needs Hep B vax? • Hepatitis B series (3 dose) : • All health care workers; • All diabetics < 60; • > 1 sex partner over last 6 months

  27. The Big 5: Shingles Shingles FACTS • If had chickenpox…… at risk for shingles • More that 90% of all adults in the United States infected with varicella zoster virus • One million cases/ year • Lifetime risk: 30% • Risk increases with age (starting at age 50)

  28. Key HZ symptom: Pain • Pain prior to rash onset: 84% of cases • Starts as abnormal skin sensation, itching or tingling • Precedes rash by 1-5 days but occasionally weeks or more • Diagnostic dilemmas & work-ups (e.g., cardiac, gallbladder) • Pain once rash develops: 89% of cases

  29. Shingles Pain… • excruciating (like renal colic, childbirth) • aching, burning, stabbing, shock-like • Continuous or paroxysmal • Altered or painful sensitivity to touch (paresthesia, dysesthesia) • Provoked by trivial stimuli like bed sheets (allodynia) • Exaggerated, prolonged response to pain (hyperesthesia) • Unbearable itching Post herpetic neuralgia (PHN) • May persist months / years

  30. PHN can Impact Quality of Life • Comparable to congestive heart failure, diabetes, and depression. Schmader KE. Clin Infect Dis2001;32(10):1481-6

  31. Risk Factors for PHN • Gender: • Risk greater in women • Dermatome • Possibly increased after HZ involving eye • Immunosuppression? : NO • NOT strongly associated with PHN • Age is the key risk factor for developing PHN • Rare in HZ patients <40 yrs • Risk of pain at >30 days:  14.7-fold in HZ patients >50 yrs • Risk of pain at >60 days:  27.3-fold in HZ patients >50 yrs • Risk of pain at >60 days:  12% for each incremental yr of age • Increasing age increases risk of getting shingles AND risk of progression to PHN

  32. Shingles vaccine (varicella zoster vaccine) • brand name Zostavax (by Merck) • The Shingles Prevention Study NEJM June 2, 2005 • 38,500+ patients 60 and older • Vaccine Effectiveness: • reduced incidence shingles by 51% • reduced incidence of PHN by 66.5% • risk of PHN (post herpetic neuralgia) increases after age 50

  33. Shingles vaccine: for prevention of shinglesWho should get it? • May 2006 - FDA approved: Age 60 & older • October 2006: ACIP recommends dose at age 60+ •  March 2011- FDA approved- expanded to 50-59 • Vaccine supply problems: • June 2011: ACIP still recommends start at age 60+ • Vaccine supply stabilized • Concerns that those vaccinated at younger age (50-60) might not be protected at older ages when the risk of severe disease is higher • ACIP says: Start vaccinating at age 60+ • Cost: $187 (source CDC)

  34. Varicella-Zoster: One virus, two diseases • May 2006 – (shingles vaccine) Zostavax approved by FDA • March 1995 –(chicken pox vaccine ) Varivax approved by FDA

  35. Chickenpox vaccine (Varivax)2doses, at least 4 weeks apart • Generally- if born in U.S. before 1980 – you are considered to be “immune”- • But this does not apply to health-care personnel and pregnant women,- • Birth before 1980 should not be considered evidence of immunity • Check the footnotes on the adult schedule for further details. • Target new mothers and women of child bearing potential

  36. Shingles Vaccine: ACIP Recommendations • You don’t have to check varicella history or titers before administering HZV • Just about everyone ≥60 has serologic evidence of prior varicella, even if they do not recall having the illness • No evidence that giving Shingles vaccine to someone without prior varicella raises safety concerns • Determining varicella history: a major and unnecessary barrier to vaccination

  37. Shingles (Herpes Zoster) Vaccine : Storage & Handling • Must be stored frozen • Must be stored at freezer temperature (≤5º F) • HZV is the ONLY freezer-requiring vaccine for adults • Need dedicated freezer only: combined fridge/freezer models may not work • Can reduce fridge temps below freezing and ruin refrigerated vaccines • Unused HZV must be discarded 30 min after reconstitution

  38. The Big 5: Pneumococcal Vaccine FACTS about Streptococcus pneumonia (aka the pneumococcus) • Kills 4000 in US each year (mostly adults) • Leading cause of serious illness: bacteremia, meningitis, pneumonia • Source: MMWR Oct 12, 2012 , 816-819

  39. Two Pneumococcal vaccines- FDA approved for adults • Pneumococcal Polysaccharide vaccine (PPSV 23- Pneumovax 23 by Merck) • Licensed for routine use in adults 50 & older and age 2–49 with certain risk factors • Private sector cost: $ 72 (source CDC) • Pneumococcal Conjugate vaccine (PCV 13- Prevnar by Pfizer) • FDA approved for use in adults age 50 and older in December 2011 NOTE: Prevnar 13 is NOT FDA approved for age 18 to 49! • Private sector cost: $152 (source CDC)

  40. PPSV 23 Recommendations for Adults MMWR, September 3, 2010, Vol 59, #34 • All adults aged 65 years or older • Adults younger than 65 years • chronic lung disease (incl. COPD, emphysema, and asthma) • chronic cardiovascular diseases • diabetes mellitus • chronic renal failure, nephrotic syndrome • chronic liver disease (including cirrhosis), alcoholism, • cochlear implants, cerebrospinal fluid leaks, • immunocompromising conditions (incl. HIV) • functional / anatomic asplenia (incl. sickle cell disease & other hemoglobinopathies, • Residents of nursing homes or long-term care facilities; and • Smokers • When indicated, if uncertain of vax status, vaccinate

  41. In Footnotes: Pneumococcal vaccine- whether and when to revaccinate withPPSV 23 • For patents under age 65: • One time PPSV 23 revaccination after five years for high risk • chronic renal failure, nephrotic syndrome, • sickle cell disease, • splenectomy, and • immunocompromised patients. • When previously vaccinated patients reach age 65: • One time PPSV 23 revaccination : if more than five years have passed since the last vaccination & patient < 65 at time of primary vaccination.

  42. Invasive Pneumococcal Disease: Risk is increased in immunocompromised adults MMWR Oct 12, 2012 , 816-819. • **Risk in immunocompromised can be 20 times than for adults without high risk medical conditions** • June 2012: ACIP recommended routine PCV 13 conjugate for immunocompromised adults: (off label use- not FDA approved for adults < 50)

  43. Invasive Pneumococcal Disease:Risk is increased in older adults MMWR Oct 12, 2012 , 816-819. • **Risk of invasive disease in older adults is 10 times higher than in younger adults ** • Risk of invasive disease • Adults 18-64: 3.8 per 100,000 • Adults 65 &older: 36.4 per 100,000 (“10 times higher”)

  44. Pneumococcal Infection in Adults 2013: Estimated 13,500 cases of invasive pneumococcal disease (IPD) in adults 65 and older • In adults 65 and older: PCV 13 serotypes were to blame for • 20-25% of IPD • 10% of community-acquired pneumonia (CAP) • Potentially preventable with PCV 13 vaccine • ACIP recs are now evidence based • Wait for CAPiTA results--presented to ACIP June 2014

  45. CAPiTACommunity Acquired Pneumonia Immunization Trial in Adults • Randomized controlled trial of PCV 13 • 85,000 seniors: PCV 13 or placebo • PCV 13 was effective! • 75% effective in preventing vaccine type invasive pneumococcal disease (IPD) • 45% effective in preventing vaccine type non bacteremic pneumonia (NBP)

  46. Emergency ACIP Meeting on August 13, 2014 • Purpose: vote on routine use for PCV 13 for all seniors • VOTE: 13 to 2- in favor of Routine PCV 13 vaccination for all age 65 /+ (in addition to PPSV 23) • Based on strong quality evidence

  47. PCV 13 and PPSV 23 can NOT be given at the same time! ACIP recs: • The minimum acceptable interval between the PCV13 and then PPSV23: 8 weeks • Recommended interval between the PCV13 and then PPSV23 : 6-12 months • Adults 65 years of age or older who have previously received PPSV23 should receive the PCV 13 at least 1 year aftertheir most recent dose of PPSV23. • Medicare coverage parameters are different

  48. 65 & older Timing “ACIP Guidance” • PCV 13………………..PPSV23 6-12 months • PPSV23……………….PCV13 at least a year • PPSV23(before age 65) ……….PPSV 23(65 & +) 5 years

  49. Pneumococcal vaccination is covered under Medicare Part B Source: http://www.medicare.gov/coverage/pneumococcal-shots.html • Medicare Part B (Medical Insurance) covers a pneumococcal shot to prevent pneumococcal infections (like certain types of pneumonia). • Part B also covers a different second shot 11 months after the exam where you got the first shot.
