PAHO's Revolving Fund let small countries buy vaccines as one bloc
Since 1979, PAHO members prepay into one pool that buys vaccines for all — PAHO says purchases run up to 75% cheaper than buying alone.

the move
After the Expanded Program on Immunization launched in 1974, PAHO's 1978 Pan American Sanitary Conference resolution established working capital for a revolving fund. The Revolving Fund for vaccine procurement began operating in 1979, pooling purchases for member states based on solidarity, quality and transparency.
Countries order vaccines and prepay in dollars; the fund purchases centrally and replenishes itself as members pay — hence 'revolving.' The pooled capital lets PAHO negotiate with manufacturers as one buyer and hold inventory so small countries do not face shortages or premium prices.
PAHO reports the fund has operated for more than 40 years, purchased over 400 million vaccines in 2022, and buys vaccines up to 75 percent cheaper than countries could on their own.
why it works
- Pooled demand gave small countries volume-purchase power.
- Prepaid working capital made the fund self-sustaining and 'revolving.'
- Central buying standardized quality and access across the region.
- The mechanism smoothed supply shocks for small national programs.
what transfers
If you are small, don't buy alone: pool demand, precommit capital, and let one buyer negotiate for all. The pool gets volume prices and stable supply no member could obtain alone.
what came after
The Revolving Fund became the procurement backbone of immunization in the Americas, credited with helping drive the region's dramatic vaccination gains, and its pooling logic is cited as the model that later pooled procurement mechanisms built on.
