Health systems that have strong primary health care at their core have overall better patient outcomes. Primary health care is key to achieving Universal Health Coverage and the broader health-related Sustainable Development Goals by 2030. In 2018, at the launch of the Declaration of Astana, the World Health Organization formed the inaugural Primary Health Care Young Leaders’ Network. This paper aims to demonstrate the scope for young professional-led communities of practice in fostering support systems for young leaders and strengthening the delivery of primary health care at multiple levels.
