A promising new vaccine candidate is getting a flurry of attention this week, even in a very crowded landscape that includes 11 vaccines on the market and 50+ more in Phase 2 or 3 trials. The newcomer NDV-HXP-S vaccine, developed through collaborations between researchers at University of Texas at Austin, PATH, and Mount Sinai, among others, is a mouthful to say but the name captures the two reasons people are excited about it.

The global imbalance in Covid-19 vaccines is often framed in terms of wealthy versus poor countries. While it can be summed that way (wealthy countries do have the majority of doses, while low-income countries have almost none), this overlooks the experience of upper-middle income countries (UMICs), such as Brazil, Indonesia, and China.
