Vaccine History
• 1794-Dr. Edward Jenner• 1952-Polio vaccine• 1963-Measles vaccine• 1974-Expanded Program on Immunization
• 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”

Solution space where
lives are saved
Industry willing to supply
Donors & countries willing to pay
Countries willing & able to introduce
Pneumococcal conjugate vaccine• Licensed in 2000• Leading cause of childhood pneumonia &
meningitis deaths• Proven safe, effective

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
Surveillance documents disease patterns
Epidemiology, effectiveness, & economics
WHO Disease Burden Estimates by Country
Serotype Distribution by Region
?How much pneumococcal disease do we have in children?
?How well with the vaccine match our serotypes?
Epidemiology, effectiveness, & economics
Cost-Effectiveness & Health Impact Estimates by Country?How cost-effective will the vaccine be in our country?

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.
