Although adopting a vaccine-centric viewpoint, the book has highlighted problems that are not exclusive to the field of vaccines. These issues affect the production and distribution of vaccines in particular ways, but also suggest the existence of broader, systemic flaws in the production and distribution of health goods – especially those that, albeit critically needed from a public health perspective, fare poorly under predominantly market-driven paradigms. The book concludes with a short reflection on how problems observed in the vaccine ecosystem feed into the larger backdrop of persistent shortcomings in the global public health system.
