Why is new vaccine introduction important?

• Child mortality rates remain unacceptably high in many countries– Injustice– Expensive– Destabilizing

Why is new vaccine introduction important?

A Global Forecasting Model of Political Instability

by Goldstone et al.

“lower-income countries showed a higher risk of instability. This is one of the best-established results in the conflict literature, of course, so we sought to improve on it. …

Yet no model, no matter how complex, performed significantly better than models that simply used infant

mortality (logged and normalized) as a single indicator of standard of living.”

Why is new vaccine introduction important?

• Vaccines can contribute to improving child survival, economic development, & national security– Vaccines available vs leading killers of children– New vaccines available shortly– Substantial existing delivery program

Consider Hib conjugate vaccine

• Hib – a leading cause of childhood meningitis and pneumonia worldwide

• Safe, effective vaccine used since 1990 in USA and other rich countries

If you build it, they will come…

It worked in the movie but does it work for new vaccine introduction?

Global Hib Vaccine Uptake High and Low Income Countries

Vicious Cycle That Delayed Hib Vaccines

Limited supply

Higher price

Uncertain demand

3) Higher prices keep developing countries uncertain about demand and donors uncertain about financing needs

1) Uncertainty about demand in developing countries leads industry to limit investments in capacity

2) Limited vaccine supply keeps prices relatively high

Saving lives requires finding “solution space”

Mission: To improve child health and reduce mortality by accelerating the evaluation of and access to new, life-saving pneumococcal vaccines for the world’s children.

Global Alliance for Vaccines and Immunisation (GAVI): PneumoADIP

PneumoADIP strategic goals

• Strategic Goal 1: Provide information that enables national decision-makers, the GAVI board and its partners to make an evidence-based decision regarding the use of vaccine.

• Strategic Goal 2: Accelerate the availability of affordable, new vaccines appropriate for use in developing countries.

“Solution space” status: 2003

• No financing for vaccine purchase• “Too expensive to manufacture/Never affordable”

Industry Willing to

Supply

Supply limited; just enough for rich countries

Vaccines $60/dose; doesn’t include vial sizes countries want

CountriesWilling toIntroduce

No WHO recommendation

No WHO disease burden estimates by country

Donors/CountriesWilling toFinance

Investment case

Major PneumoADIP accomplishments“GAVI’s efforts have truly accelerated the demand for

pneumococcal vaccines.”– GAVI Phase 2 Independent Evaluation

“Solution space” status: 2008

• GAVI Board endorsed Investment Case for Pneumococcal Vaccines

• $1.5 billion for an Advance Market Commitment for pneumococcal vaccines

Industry Willing to

Supply

Multinational & emerging manufacturers now committed to supply GAVI countries

Vaccines will have high serotype coverage, affordable price, and good vial size

CountriesWilling toIntroduce

WHO recommends pneumococcal vaccine in routine immunization programs

8 approvals, 3 conditional approvals & 34 expressions of interest

Main takeaways

1. Dedicated team1. Team that “sweats the details” every day

2. Use evidence to set consensus & policies1. Need “push” to move into implementation

3. Strategic demand forecast1. Lays out “what will it take” for each stakeholder

Evidence to policy to implementation

Levine OS et al. Curr Op Infect Dis 2010

Moving from policy to implementation

Can feel like it’s a lot to handlehttp://www.youtube.com/watch?v=8NPzLBSBzPI

Opportunities & Challenges

Opportunities• Impact on child health &

economies• Success breeds success• Improved equity

Challenges• Biggest ever coordination

needed• Maintaining focus in face of

competing priorities• Economic setbacks

More than 40 countries by 2015

Following the May 2011 round, almost 70% of GAVI countries have sought support for PCV introduction. A total of 37 GAVI-eligible countries have been approved for GAVI support to introduce pneumococcal conjugate vaccine into

their national immunisation programmes.

With an additional 18 countries approved as of September 2011, pneumococcal vaccines will soon be administered in more than half of GAVI eligible countries.

This is an unprecedented rapid ramp up.

To date, 14 countries in the developing world have begun the introduction of pneumococcal vaccines. By rapidly scaling up the number of countries and the

number of children receiving the vaccines, GAVI and its partners can avert over 650,000 deaths by 2015 and up to seven million deaths by 2030.
