HAI works to increase access and improve the rational use of essential medicines. HAI is working towards a world where all people, especially the poor and disadvantaged are able to exercise their human right to health, which requires equitable access to affordable quality health care and essential medicines. HAI and its global partners recognize that poverty and social injustice are the greatest barriers to health and sustainable development. Partners are working for just societies where people can participate equitably in all decision making that affects their health and well being, including the allocation of resources. HAI’s strength is to enable consumers, health care providers, public interest NGOs and policy makers to collaborate based on mutual interests and common positions to advocate for policy changes and improved health for all. Partners work together to respond rapidly to priority issues by sharing information and expertise. Collaboration creates a broad base of support and ensures that the concerns of diverse communities are communicated at local, regional and international levels.
