The Global Vaccine Action Plan - insights into its utility, application, and ways to strengthen future plans.

BACKGROUND: The pace of global progress must increase if the Global Vaccine Action Plan (GVAP) goals are to be achieved by 2020. We administered a two-phase survey to key immunization stakeholders to assess the utility and application of GVAP, including how it has impacted country immunization programs, and to find ways to strengthen the next 10-year plan. METHODS: For the Phase I survey, an online questionnaire was sent to global immunization stakeholders in summer 2017. The Phase II survey was sent to regional and national immunization stakeholders in summer 2018, including WHO Regional Advisors on Immunization, Expanded Programme on Immunization managers, and WHO and UNICEF country representatives from 20 countries. Countries were selected based on improvements (10) versus decreases (10) in DTP3 coverage from 2010 to 2016. RESULTS: Global immunization stakeholders (n = 38) cite global progress in improving vaccine delivery (88%) and engaging civil society organizations as advocates for vaccines (83%). Among regional and national immunization stakeholders (n = 58), 70% indicated reaching mobile and underserved populations with vaccination activities as a major challenge. The top ranked activities for helping country programs achieve progress toward GVAP goals include improved monitoring of vaccination coverage and upgrading disease surveillance systems. Most respondents (96%) indicated GVAP as useful for determining immunization priorities and 95% were supportive of a post-2020 GVAP strategy. CONCLUSIONS: Immunization stakeholders see GVAP as a useful tool, and there is cause for excitement as the global immunization community looks toward the next decade of vaccines. The next 10-year plan should attempt to increase political will, align immunization activities with other health system agendas, and address important issues like reaching mobile/migrant populations and improving data reporting systems.

Protecting the Community Through Child Vaccination.

The direct impact of vaccines on children is well described, but the major public health impact of indirect protection provided to the community by vaccines is underappreciated. Community protection occurs when vaccinated persons block the chain of transmission, protecting undervaccinated or unvaccinated susceptible community members by preventing exposure and limiting the spread of the pathogen through the community. Substantial declines in disease incidence have occurred shortly after implementing new childhood vaccines, including declines among vaccine-ineligible children, adolescents, and adults. Protection of susceptible community members depends on maintaining high vaccination rates. Improved recognition of community protection will strengthen childhood vaccination strategies that will protect our communities into the future.
