Interesting read from this recent paper that nicely summarizes some of the key challenges and opportunities in routine immunization according to 8 core components of 1. Policy, standards, and guidelines 2. Governance, organization, and management 3. Human resources 4. Vaccine, cold chain, and logistics management 5. Service delivery 6. Communication and community partnerships 7. Data generation and use 8. Sustainable financing http://www.ghspjournal.org/content/2/4/381.full Thanks said, were the authors are viewing where new investments are needed to strengthen vaccine, cold chain and logistics management for the future is fairly limited. In my view, there is more needed than more tools to support better forecasting and developing new vaccine technologies.
