Increased swine influenza detection in
humans 2005-9
• January 2007 – “Novel influenza A” made a Nationally
Notifiable Disease but CSTE – part of pandemic
preparedness efforts
• RT-PCR for influenza capabilities developed by public
health labs in U.S.
• Increasing numbers of swine influenza infections in
humans being detected from improved surveillance
• Increasing efforts at states, CDC, and USDA to
investigate human cases of swine influenza

United States, 2005–2009

Antiviral Treatment Recommendations
 Priority: Hospitalized Patients with suspected
or confirmed pandemic H1N1 virus infection
• Treatment recommended with Oseltamivir or Zanamivir
• Treat patients as soon as possible (duration: 5 days)
 Outpatients with suspected or confirmed
pandemic H1N1 virus infection who are at
high risk for complications
• Persons with chronic pulmonary, cardiac, renal,
hepatic, metabolic, hematological disorders;
immunosuppression, pregnant women, children <5
years; adults ≥65 years
http://www.cdc.gov/h1n1flu/recommendations.htm
• Treatment
recommended with Oseltamivir or Zanamivir
• Treat patients as soon as possible (duration: 5 days)
www.cdc.gov/H1N1flu
Antiviral Chemoprophylaxis
 Post-exposure chemoprophylaxis with Oseltamivir or
Zanamivir can be considered:
• Close contacts of cases who are at high risk for
complications of influenza
• Health care personnel, public health workers, first
responders with unprotected close contact
exposure to an ill person with pandemic H1N1 virus
infection while in the infectious period
• Chemoprophylaxis: 7-10 days after last known
exposure
http://www.cdc.gov/h1n1flu/recommendations.htm
www.cdc.gov/H1N1flu
Summary of key points
 Once emerged, pandemic H1N1 virus spread to all 5
states and globally quickly
 Some areas more affected than others
 Expect continued summertime circulation with focal
outbreaks
 Elderly seemingly relatively spared
 Capable of causing severe disease and death
 Most severe outcomes among people with
underlying heath problems that are associated
with high risk of influenza complications
 Virus remains sensitive to oseltamivir and zanamvir
www.cdc.gov/H1N1flu
What’s Next
 Disease likely persists
through summer in US,
expected surge in fall
 Severity of Fall epidemic
difficult to predict
 Southern Hemisphere
being monitored for
subtypes, spread, and
severity
 Vaccine being readied
 Surveillance continuing

New Horizons
H1N1 Vaccines

National Strategy for Pandemic Influenza (Nov. 2005)
goal is to provide vaccine to everyone in U.S. w/in 6
mo. of pandemic onset
 H1N1 Vaccine Strategy follows pandemic playbook
for vaccine development, production, and
administration
 Clinical studies will inform vaccine formulation and
safety profile
 Key decision issues:
 Vaccine product type
 Use of thimerosal preservative
 Use of oil-in-water adjuvant
 Post-vaccination safety monitoring
Courtesy Robin Robinson, PhD, HHS/ASPR/BARDA Director
www.cdc.gov/H1N1flu
Phases of a vaccination program
 Vaccine development
 Commercial scale manufacturing
 Distribution and administration
 Post-launch effectiveness, safety and
utilization monitoring
www.cdc.gov/H1N1flu
Vaccine development
 Vaccine reference strain development
 Master seed strain preparation
 Clinical investigational lot manufacturing
 Clinical studies
 To assess immunologic response and
safety
 Will inform formulation decisions
www.cdc.gov/H1N1flu
Commercial scale production
 Potency assay reagents preparation and
calibration
 Commercial scale bulk antigen manufacturing
without adjuvant
 Commercial bulk antigen manufacturing with
adjuvant
 Bulk adjuvant manufacturing
 Commercial scale syringe/needle manufacturing
 Vaccine formulation fill-finish

- Also manufactures MF59 adjuvant for potential
pre-formulation with vaccine
 Sanofi Pasteur (26.4%)
 CSL (18.7%)
 MedImmune (5.8%)
 GSK (3.4%)
- Also manufactures ASO3 adjuvant in a separate

Vaccine products (general)
 Unadjuvanted multidose vials*
 Unadjuvanted p-free pre-loaded syringes†

*All
multidose vials will contain thimerosal preservative
†Up
to 20% of vaccine may be p-free pediatric formulation

Emergency Use Authorization
“… use of an unapproved medical product or an
unapproved use of an approved medical product
during a declared emergency …”
- Unadjuvanted pandemic H1N1 vaccine may be
licensed in a manner similar to a seasonal flu
vaccine strain change and therefore would not
need an EUA
- Adjuvanted vaccines, if used (for the 2009-10 flu
season), will be administered under an EUA

Pandemic H1N1 Vaccine:
Program Implementation
Pascale Wortley, MD, MPH
Immunization Services Division
Centers for Disease Control and Prevention
July 15, 2009
www.cdc.gov/H1N1flu
Vaccine purchase, allocation, and
distribution
 Vaccine procured and purchased by US
government
 Vaccine will be allocated across states
proportional to population
 Vaccine will be sent to state-designated
receiving sites: mix of local health
departments and private settings
www.cdc.gov/H1N1flu
Vaccine planning assumptions:
 Vaccine available starting mid-October
 Initial amount: 40, 80, or 160 million doses
over one month period
 Subsequent weekly production: 10, 20 or 30
million doses
 2 doses required
 Preservative free single dose syringes for
young children and pregnant women
www.cdc.gov/H1N1flu
Vaccine planning assumptions:
Populations to plan for:
Students and staff (all ages) associated with schools
(K-12) and children (age >6 m) and staff (all ages) in
child care centers
 Pregnant women, children 6m-4yrs, new parents
and household contacts of children <6 months of
age
 Non-elderly adults (age <65) with medical conditions
that increase risk of influenza
 Health care workers and emergency services
personnel
www.cdc.gov/H1N1flu
Delivery model
Public health-coordinated effort that blends
vaccination in public health-organized clinics
and in the private sector (provider offices,
workplaces, retail settings)
Private sector providers who wish
to administer H1N1 vaccine will
need to enter into an agreement
with public health in order to
receive vaccine
www.cdc.gov/H1N1flu
Public Health planning efforts
 Reaching out to private providers (defined broadly) to
assess interest in providing H1N1 vaccine
 Retail sector, pharmacists may be involved
 Planning large scale clinics
- Especially important for school-age children given
limited private sector capacity
www.cdc.gov/H1N1flu
Issues for administration in
provider offices
 Storage capacity
 Administering according to recommended
age groups
 Reporting doses administered early on
 Insurance reimbursement for administration
www.cdc.gov/H1N1flu
Monitoring vaccine coverage
 Initially, states will be required to report doses
administered on a weekly basis
 Transition to assessment via population
surveys (BRFSS, NIS)
www.cdc.gov/H1N1flu
Monitoring vaccine safety
 Vaccine Adverse Event Reporting System
(1-800-822-7967, http://vaers.hhs.gov/contact.htm ) for signal
detection
 Network of managed care organizations
representing approximately 3% of the U.S.
population, the Vaccine Safety Datalink
(VSD) to test signals.
 Active surveillance for Guillain Barre
Syndrome through states participating in
Emerging Infections Program.
www.cdc.gov/H1N1flu
Monitoring vaccine effectiveness (VE)
 VE for prevention of PCR-confirmed medically
attended influenza at 4 community-based sites
 VE for prevention of influenza hospitalizations
diagnosed by provider-ordered clinically available
tests at 10 sites nationwide through the Emerging
Infections Program
 DoD will be assessing VE in active duty service
members
