The innovative trial was supposed to roll out across multiple African nations and had been set up to find the best way to encourage the human immune system to create legions of special, broadly neutralizing antibodies.
Penny Moore is a virologist at the University of Witwatersrand in South Africa.
But early last year, she says the $45 million grant they'd received from USAID to do the work was canceled as part of a broader effort by the Trump administration to extinguish foreign aid.
The team scrambled to secure a much smaller amount of other funding and scaled the trial way back to take place within South Africa only.

To really confirm the ring-counting approach, one would need to study live dinosaurs.
The next best thing are their living relatives, including crocodiles.
Their skeletons tell a story about how they grew.
University of Cape Town paleobiologist Anousia Chinsami-Taran and her colleagues...
injected several crocs with an antibiotic which got taken up in their bones.
When they later looked at those bones, they found more rings than expected.
This may have implications for dinosaur bones, suggesting some dinos may have been younger when they perished than previously thought.
Researchers not involved in the study, however, argue it's premature to throw out growth rings as annual age markers.
