Access to essential medicines remains a challenge globally. Over 2 billion people still lack regular access to medicines. Ensuring access to medicines can reduce conflict by decreasing inequalities and increasing trust in government institutions. Providing a basic package of essential medicines to developing countries would cost $77-152 billion annually but could be purchased for as little as $13-25 per person per year. Rotary can play a role in improving access through supporting local ownership, incentives for equitable distribution, institutional partnerships, and operating within existing legal and ethical rules to serve as a link between health and peace.
