The removal of U.S. support reflects an administration focus on domestic priorities, forcing South Africa to scramble for national funding to sustain critical HIV research.

Overview

  • President Donald Trump’s administration cut all USAID and PEPFAR funding earlier this year, eliminating about $400 million in annual aid to South Africa’s HIV programs.
  • The abrupt withdrawal of a $46 million grant halted the BRILLIANT vaccine trial days before it was set to begin in Johannesburg.
  • The funding pullback has rendered major laboratories idle and led to layoffs of around 100 researchers and 8,000 health workers.
  • Universities South Africa has applied for more than $110 million in emergency support as the government warns of a $107 million research funding shortfall over the next five years.
  • The disruption threatens ongoing lenacapavir studies and undermines South Africa’s role in global HIV and pandemic vaccine development.
