Vaccines & 21st Century
Evolving Standards & Knowledge
• Prescription drugs
– Diversity of responses seen post-marketing
– Vaccines as “orphan prescription drugs”
– Apply standards for prescribing any drug to vaccines
• Safe and effective: population to individual
– FDA & Public Health/CDC perspectives
– Operational medicine perspective
– Provider perspective
– Patient/Individual vaccinee perspective
• Need: improved life cycle safety surveillance
– Understanding gender, racial/ethnic/genetic differences
– Evidence-based practice improvements
Knowledge Gaps & Unmet Needs
Beyond Epidemiology and FDA Guided Studies
“Undermining the public trust . . “
1st: “inadequate ongoing, credible education
of the public and health professions
concerning the known and unknown benefits
and risks of vaccines.”
2nd: grossly insufficient investment in
research on the safety of immunization.

Non-IgE Mediated Vaccine Reactions 2012 Updates
An Expanding Platform of
Challenges in Immunization
• Updates and Highlights
– TdaP/Td: New vaccine information sheet 24Jan12
• Tdap: Fever over 102 F (about 1 in 100 adolescents and 1 in 250
adults), Headache (1 in 300), nausea, vomiting, diarrhea, stomach
ache (up to 3 in 100 adolescents and 1 in 100 adults)
• Dose after 20 weeks pregnancy, elderly in contact with infants
• NEW: with each pregnancy even if less than 3 years apart!
• Risk of repeated TdaP every few years with new guidelines
– Influenza vaccine ingredients:
Oculo-respiratory Syndrome
2000 Canadian Case Definition of ORS
• At least one of the following symptoms: bilateral conjunctivitis, respiratory
problem (chest tightness, difficulty breathing, wheezing), and oropharyngeal
edema, or any combination of these conditions within 24 hours of receiving the
vaccine. Exclusions: URI prior to or after immunization.
http://www.collectionscanada.gc.ca/webarchives/20071222064231/http://www.phac-aspc.gc.ca/publicat/ccdrrmtc/01vol27/dr2710ea.html
• Attack Rate of 3.4% (95% CI 2.4-4.4%)
• Evolved case definition to 2 symptoms for
specificity
Age-group distribution (years) of ORS cases for 20002001 to 2003-2004 influenza seasons (n=3264)
• FluMist: egg, MSG, gentamicin, gelatin, arginine
• Fluzone: egg, formaldehyde, gelatin, thimerosal (multi-dose),
latex(single)
– Afluria: egg, neomycin, polymyxin B, thimerosal (multi-dose vials)
2 Deaths/males: age 72
(day 54) and age 66 (day

Initial Evidence of Increased Risk for
Febrile Seizures: MMRV vs MMR+V
• Measles-mumps-rubella plus varicella: MMRV
– MMRV combination vaccine to morbidity of shot #s
• ACIP preferential recommendation MMRV over MMR+V
• Post-licensure Safety Surveillance Studies
– Vaccine Safety Data Link (VSD): confirmatory study
• Demonstrated ~2 fold increased risk of febrile seizures (12-23
months) when MMRV in a single injection versus in 2 shots
− MMWR Morb Mortal Wkly Rep. 2008 Mar 14;57(10):258-60.
Update: recommendations from the Advisory Committee on
Immunization Practices (ACIP) with update in 2009
– ACIP removes previous preference recommendation
• Provider must make benefit-risk information available to enable
choice of MMR+V versus MMRV
− Complex risk communication in a setting of limited time
Neurologic Immune Inflammatory Reactions
Recurrent Guillain-Barré Syndrome Following Vaccination
• GBS: acute polyradiculopathy, probably autoimmune
– Reported as a rare but serious vaccine adverse event
– ACIP recommends no influenza vaccine to individuals with a prior
history of GBS within 6 weeks of a prior FLU vaccine IF not at higher
risk of severe complications from influenza illness
• Northern California Kaiser Study Clin Infect Dis 2012;54(6):800–4
– 1995-2006: hospital discharge diagnoses, neurology reviewed GBS
– 550 cases of GBS over 33 million person-years, 6 with recurrence
• 989 vaccines given to 279 of these individuals with 405 TIV vaccine
doses given to 107 individuals with prior Dx of GBS
• 18 had GBS with 6 weeks following FLU vaccine – 2 revaccinated
without recurrence
– Limitations of study: selection bias so at greatest risk for recurrence
were not revaccinated?

Inactivated Trivalent Influenza Vaccine
and Pneumococcal Vaccine (PCV13)
• Febrile Seizures
– Occur in 2-5% of all children: generally benign outcome
– INCREASED RATE in children, especially 12-23 months, compared
with those who received vaccines separately
– ACTUAL RISK: 1 additional seizure in every 2225 children vaccinated
– WHAT IS RISK of delaying one vaccine at well –baby visits?
• Why Vaccinate with FLU Vaccine? MMWR Sep 16, 2011
– 2010-11: 115 children in US died from influenza
– 50% of deaths occurred in children < 5 years of age
• 17/74 (23%) had been vaccinated with TIV
• Why Vaccinate with Pneumococcal Vaccine?
– Pneumococcal disease: 1 million deaths annually worldwide (<5 yrs)
– 13% of all infections in children, major cause of pneumonia
– Rates of disease reduced in all ages with vaccine: 20% pneumonia
Autoimmune Responses
Influenza Vaccine? (Lupus. 2012;21(2):175-83.)
• Autoimmune Inflammatory Rheumatic Disease (AIRD)
– Prospective cohort study with 6 months follow-up: 218 patients AIRD
• 50 vaccinated with seasonal FLU, 6 with H1N1, 104 with both
• 58 non-vaccinated controls
– Healthy controls: 41 subjects (9 seasonal FLU, 3 H1N1, 18 both)
• Outcome Measures: Autoantibodies
– ANA, ENA, aCL IgG/IgM, anti-beta2-glycoprotein
• Antinuclear antibody (ANA), anti-extractable nuclear antigen (anti-ENA),
anticardiolipin (aCL) IgG/IgM antibodies, anti-beta 2-glycoprotein I (anti-β2GPI)]
– Baseline, 1 (AIRD only) and 6 month post vaccine
• Results
– Transient changes in autoantibody production in AIRD & controls
– Small subset: tendency toward anti-ENA development (ANA+ pts)
– H1N1 – aCL induction in some

Adverse Events Following
12 & 18 Months Vaccinations
• Population-based, self-controlled case series
– 271,495 12-month vaccinations
– 184,312 18-month vaccinations
• Relative incidence of ER visits or hospital admissions
– Consecutive one day intervals following vaccination
– Compared to control period 20-28 days later
– Post-hoc analysis: reasons for ER visits, average acuity score for 12month vaccines. NOTE: No increase in hospitalizations seen
• Results
– 4-12 days post 12 months vaccines, RR incidence: 1.33 (1.29-1.38)
• 1 excess event during risk interval every 168 children vaccinated
– 10-12 days post 18-month vaccines: RRI 1.25 (1.17-1.33)
• 1 excess event for every 730 children vaccinated

• Goal: Updated scientific basis for review and adjudication of
claims of vaccine injury by the VICP
– Lesson learned: “some issues simply cannot be resolved with
currently available epidemiologic data, excellent as some of the
collections and studies are.” www.iom.edu/Reports/2011/AdverseEffects-of-Vaccines-Evidence-and-Causality.aspx
– Outcomes: 134 “insufficient evidence to accept or refute a causal
relationship”; 24 consensus for or against causal association

Adverse Effects of Vaccines: Evidence & Causality
Evidence Supports Causal Relationship
• Consensus Report: August 25, 2011
– www.iom.edu/Reports/2011/Adverse-Effects-of-Vaccines-Evidence-and-Causality.aspx - New
Categories of Causation Agreed on!
• Reviewed 8 of 12 covered vaccines: varicella zoster, influenza (not H1N1), hepatitis B,
HPV, MMR, Hepatitis A, meningococcal, tetanus-containing vaccines (aP)
• Evidence convincingly supports a causal relationship
– Example: paralytic polio and oral polio vaccine
• Evidence favors acceptance of a causal relationship
– Evidence is strong and generally suggestive, although not firm enough to be
described as convincing or established.
• Evidence is inadequate to accept or reject a causal relationship
– The evidence is not reasonably convincing either in support of or against
causality; evidence that is sparse, conflicting, of weak quality, or merely
suggestive— whether toward or away from causality —falls into this category.
Where there is no evidence meeting the standards described above, the
committee also uses this causal conclusion.
• Evidence favors rejection of a causal relationship
– The evidence is strong and generally convincing, and suggests there is no causal
relationship.
Evidence Convincingly Supports a Causal Relationship
• Varicella Vaccine:
– Disseminated varicella infection rash after vaccination
– Disseminated varicella infection with subsequent infection resulting in
pneumonia, meningitis, or hepatitis in individuals with demonstrated
immunodeficiencies
– Vaccine strain viral reactivation (appearance of chickenpox rash
months to years after vaccination
– Vaccine strain viral reactivation with subsequent infection resulting in
meningitis or encephalitis (inflammation of the brain)
• MMR Vaccine
– Linked to disease called measles inclusion body encephalitis
• In very rare cases, can affect people whose immune systems are
compromised and usually occurs within a year of acute infection or
vaccination

Evidence Convincingly Supports a Causal Relationship
• MMR Vaccine
– Linked to disease called measles inclusion body encephalitis
• In very rare cases, can affect people whose immune systems are
compromised and usually occurs within a year of acute infection or
vaccination
– Linked to febrile seizures
• Generally benign and hold no long term consequences
• NOTE: enhanced risk when MMRV used versus MMR & V
• 6 Vaccines Linked to Anaphylaxis
– MMR, varicella zoster, influenza, hepatitis B, meningococcal,
tetanus-containing vaccines
• Injection of Vaccine, Independent of Antigen Involved
– Syncope (risk of fall complications described)
– Deltoid bursitis (frozen shoulder): shoulder pain, loss of motion
From the desk of RJM Engler, MD: 2013
Evidence Favors Acceptance of a Causal Relationship
(Evidence favors acceptance of 4 vaccine AEFI: strong and
generally suggestive but not firm enough to be convincing)
• HPV vaccine and anaphylaxis
• MMR vaccine and Transient Arthralgia (temporary joint
pain) in female adults
• MMR vaccine and transient arthralgia in children
• Certain trivalent influenza vaccines used in Canada in
some recent years and mild/temporary oculorespiratory
syndrome
– Conjunctivitis, facial swelling, upper respiratory symptoms including
cough and wheezing

New Framework for Evidence Based Guidelines
• Advisory Committee on Immunization Practices (ACIP)
– Expert advice/guidance to Director CDC and Secretary, HHS
– Basis of Evidence Based Recommendations:
• Grading of Recommendations, Assessment, Development,
Evaluation (GRADE)
− Balance of benefits and harms; Type of evidence
− Values and preferences of people affected
− Health economic analyses
• Category A: for all persons in an age- or risk-factor-based group
• Category B: “for individual clinical decision making and do not apply
to all members of an age- or risk-factor-based group, but in the
context of a clinician-patient interaction, where vaccination may be
found appropriate for a person”
• New: Balance Considering Not Just Quality of Evidence
Vaccine. 2011 Nov 15;29(49):9171-6. Epub 2011 Aug 11.
MMWR Report 2010 Jun
H1N1 Vaccine Safety Surveillance: Limitations
1. Misclassification of some cases, particularly in young
–
Impact: Underestimation of GBS cases
2. Inaccurate reporting of date of vaccination
–
Impact: Overestimation or underestimation of cases in risk window
3. Rate ratio relies on vaccination coverage estimates
–
–
BFRSS and NHFS data, not actual dose delivery – 2-3% diff
Impact: Underestimation of the rate ratio
4. Incomplete case ascertainment or reporting bias
–
Active case finding surveillance
5. None of vaccine monitoring systems currently in use,
including EIP, can fully account for other confounding
risk factors for GBS
–
Cannot prove causal relationship between vaccination & GBS
Vaccine Recommendations
GRADE Evidence Approach
• Evidence Tables To Summarize
– The benefits and harms
– The strengths and limitations of the body of evidence.
– ACIP unanimous vote to adopt GRADE approach: Oct 2010
• Quality of evidence for benefits & harms only 1 factor in developing
recommendations: balance with values, health economics
• New Evidence Framework Goals
– Enhance the ACIP's decision-making process by making it
• More transparent, consistent and systematic.
– Response to challenges and criticisms
– A move towards personalized/subpopulation-focused medicine?
