Sabin, in their previous work identified that immunisation professionals play a vital role in delivering one of the world’s most powerful health interventions: vaccines. Yet, they are faced with a number of challenges which are summarised in three broad categories; 1) isolation (not having channels to communicate with peers working in other locations), 2) burn out and fatigue which leads to high turnover and 3) complex environments with ambiguous targets and little resources to achieve them. The Boost Community Platform launched in January 2020, is a global community where immunisation professionals connect, learn and lead. Its mission is to foster a global community that enables immunisation professionals to connect with peers and experts, learn skills that build capacity and advance careers, and lead immunisation programs in challenging contexts. Its vision is a world in which every immunisation professional is empowered to advance in their careers and accelerate change in their communities. Sabin role in the program is that of an adviser, a convener, and a catalyst of systemic change. It works at the country and global level to strengthen policy, secure financing, and build political will for country ownership of immunisation.

The purpose of the annual evaluation is to evaluate the  extent which Boost has realised behavioural changes (outcomes) to its targeted audience as envisioned in its theory of change. Behavioural changes has been translated to mean the extent which Boost has managed to connect and elevate the voices of immunisation professionals, facilitated navigation and learning among immunization professionals, and the impact of Boost partnering with others.  In addition,  the evaluation will identify any gaps in the implementation. The evaluation being a formative assessment, key recommendations will be provided to guide Boost implementation onwards. The evaluation focuses on the Boost implementation between January 2020 to December 2020.

By design, the evaluation is formative in nature. Formative in sense that it aims at drawing learning to inform Boost implementation moving forward and for accountability to the Boost funders. In lieu of this, the findings of the evaluation will guide Sabin and its partners to identify links between the problem, interventions and outcomes or understand if the program is realizing its Theory of Change. The recommendation will also guide Sabin and its partners make necessary adjustments so as to maximise the success of the program.

The findings also contributes to a body of knowledge repositories on the effectiveness of similar models implemented world-wide; models that are aligned to the Boost vision and thinking – for example the Advocacy Accelerator, ANDE, Digital Frontiers Institute, +Acumen among others.
