evidence: The World Health Assembly, with the support of countries and partners, has endorsed a new global vision and strategy, called the Immunization Agenda 2030 (IA2030), to address these challenges over the next decade and save over 50 million lives. [...] The IA 2030 strategy—to extend the benefits of vaccines to everyone, everywhere—is underpinned by four core principles: it puts people in the centre, is led by countries, implemented through broad partnerships, and driven by data. The IA2030 strategy systematically applies the core principles across each of the strategic priorities.
