In this powerful conversation, Mark Heywood—human rights and social justice activist and co-founder of South Africa’s Treatment Action Campaign (TAC)—joins Tracy Swan to reflect on one of the most effective grassroots movements in history. Mark recounts how HIV activism mobilized tens of thousands of people to fight back against government denialism and Big Pharma, and helped bring treatment to millions.

Together, they explore what made the movement so successful, what has changed globally since then, and why today the world urgently needs a revitalized HIV movement—one that puts communities and affected people at its center.
