Vaccine Development and Production

Moderator: Arnold MontoDiscussant: John TreanorRapporteur: Kristin Nichol

Page 3: Vaccine Development and Production

Vaccine Development and Production Issues to Consider

• Can a “strain change” approach work?

• If not, what pre-licensure data are needed?

• Is a “pandemic-only” approach commercially viable

• How can better correlates of immunity be derived?

• How can evaluation of live vaccines for pandemic influenza be facilitated?

• What is the liklihood of significant heterosubtypic/variant protection?

Page 4: Vaccine Development and Production

Vaccine Development and Production Issues to Consider

• Production Issues– How to increase US production, assuming

nationalization of supplies in a pandemic• Role of cell culture-based vaccines and use

of adjuvants

• Regulatory challenges in an era of rapid response

– How to ensure distribution according to priority recommendations for use

– Animal vs human vaccination• Regulatory issues for avian vaccines

Page 5: Vaccine Development and Production

Vaccine Deployment Issues to Consider

• How much vaccine should be stockpiled?

• How often should the stockpile be updated?

• What would be an appropriate trigger for deployment of the stockpile? For population wide vaccination?

• Should we consider pre-priming?

Page 6: Vaccine Development and Production

What is the Time frame for Development of a Vaccine and How Can it be Shortened?

Page 7: Vaccine Development and Production

What is the Feasibility for Developing an H5N1 Vaccine?

Page 8: Vaccine Development and Production

What is the Potential for Flexibility of the Backbone for a Foreign Avian Insert?

Page 9: Vaccine Development and Production

How Do We Increase US Production of a Vaccine?

• What is the potential for cell culture-based vaccines and the use of adjuvants?

• What are the regulatory challenges in an era of rapid response?

Page 10: Vaccine Development and Production

How Can Distribution According to Priority Recommendations be Ensured?

Page 11: Vaccine Development and Production

Recommendation for Vaccine Priorities

Tier 1 Sub-Tier A Vaccine and antiviral manufacturing (~40,000)

Medical workers with direct patient contact (8-9 million)

Sub-Tier B Persons 65 years with a risk condition, other age groups with two or more high risk conditions. (18.2 m, 6.9 m)

Sub-Tier C Pregnant women, contacts of children < 6 months of age, of immunocompromised. (3 m, 2.7 m, 6.9 m)

Sub-Tier D Public health emergency response workers (150,000)

Key government leaders

Tier 2 Sub-Tier A Others age groups with risk one condition (35.8 million)

Healthy 65 years and older (17.7 million)

Healthy 6-23 year olds (5.6 million)

Sub-Tier B Other emergency, utility and transportation workers. (7 m)

Sub-Tier C Other key governmental decision makers.

Funeral directors, etc. (62,000)

Sub-Tier D Rest of population (180 million)

Antiviral Priority Recommendations

1. Patients admitted to hospital Treatment

2. Health care workers with direct patient contact Treatment

3. Highest risk outpatients Treatment

4. Pandemic health responders, Public safety Treatment

5. Increased risk outpatients Treatment

6. Outbreaks in nursing home PEP

7. Healthcare workers – critical settings Prophylaxis

8. Critical infrastructure workers Treatment

9. Other outpatients Treatment

10. Highest risk outpatients Prophylaxis

11. Other healthcare workers with direct patient contact Prophylaxis

How Should We Prioritize Animal vs Human Vaccination to Control a

Pandemic?

Education and Communication

Moderator: John BartlettDiscussant: Jeffrey Levi

Rapporteur: Michael Osterholm

Page 16: Vaccine Development and Production

Education and CommunicationIssues to Consider

• Communication of the national plan

• Outreach to public and private schools and to community services

• Professional groups: medical systems, HMOs, community-based organizations

• Liaison relations with national societies and organizations (i.e. Rotary Club, Kiwanis, Lions, Chamber of Commerce, etc.)

• Enduring materials

• Professional Societies

Page 17: Vaccine Development and Production

How will the National Plan be Communicated and by Whom?

Page 18: Vaccine Development and Production

COMMUNICATION: VEHICLES

• Public: TV, radio, newspapers and Internet

• Other: Phones (?), beepers

• Electronic networks: CDC, WHO CIDPAP, IDSA, SHEA, ProMed, ATS, SCCM

Page 19: Vaccine Development and Production

Who Will Provide Outreach to Public and Private Schools and to Community Services?

Page 20: Vaccine Development and Production

COMMUNICATION: PUBLIC

• Update

• Directions: Recommendations

• Antivirals/vaccines – who, where, how, when

• Evaluations – OPDs, hospital, EW, designated facilities

• Social distancing

• Travel

• Penalties

Page 21: Vaccine Development and Production

Who Will Communicate with Professional Groups, Such as Medical Systems, HMOs, and CBOs?

Page 22: Vaccine Development and Production

COMMUNICATION: MEDICAL PERSONNEL

• Guidelines from authorative sources (DHHS)

• Policies: Regional, local institutional

• Medical updates

• Specifics: Personnel, supplies, beds, medical data, risks, resources

Page 23: Vaccine Development and Production

Who Will Handle Liaison Relations with National Societies and Organizations

(i.e. Rotary Club, Chamber of Commerce, etc.)?

Page 24: Vaccine Development and Production

Who Will Develop and Distribute Enduring materials?

Page 25: Vaccine Development and Production

COMMUNICATION: LEADERSHIP

• International: WHO

• National: DHHS

• State: Health Department

• City: Health Department

• Institutional: Appoint

• HMO: Appoint

Page 26: Vaccine Development and Production

Who Will Interface with Professional Societies?

Page 27: Vaccine Development and Production

COMMUNICATION: LESSONS

• Credibility: Mayor Guiliani (Anthrax)

• Sensitivity: St. Louis, MO (Smallpox) and 1918 pandemic flu

• Pre-plan: Baton Rouge (Katrina)

• Clarity: NYC (anthrax, WNV)

• SARS

Surveillance and Diagnostics

Moderator: Michael TapperDiscussant: Isaac Weisfuse

Rapporteur: Cathy Petti

Page 30: Vaccine Development and Production

Surveillance and DiagnosticsIssues to Consider

• Accuracy (sensitivity and specificity)

• Point of care vs. referral (confirmatory)

• Networks & uniform reporting tool (centralized data base)

• Discrimination regarding etiology of presenting respiratory illnesses

• Reporting: who, what, where, how, when

• Specimen repository (resistance testing)

• Timeliness and transparency

Page 31: Vaccine Development and Production

Surveillance and DiagnosticsIssues to Consider

• Clinical vs. laboratory diagnosis

• Point of care vs. referral (confirmatory)

• Bidirectional reporting: who, what, where,

how, when

Page 32: Vaccine Development and Production

Clinical vs. Laboratory Diagnosis

Page 33: Vaccine Development and Production

Will Diagnosis and Treatment Occur at the Point of Care or after a Confirmatory Referral?

Page 34: Vaccine Development and Production

How Will the Reporting of Cases be Handled and by Whom?

Use of Antivirals and Antiviral Development

Moderator: Andy PaviaDiscussant: John Beigel

Rapporteur: Anne Moscona

Page 37: Vaccine Development and Production

Use of Antivirals and Antiviral Development Issues to Consider

• Resistance evaluation for seasonal and pandemic influenza• Dose and duration of therapy• Special populations: elderly, pediatrics, immunocompromised• Pandemic Strategy Questions

– Therapy vs. prophylaxis– How large should drug stockpile be and what specific drugs

should it contain?– Do you agree with the NVAC guidelines for priority groups

and strategies for antiviral use as detailed in HHS Pandemic Plan?

• New compounds in development that might be available in the next 1-2 years

• Is there an adequate pipeline and development of new targets?
