vaccine

When the world thinks of vaccine breakthroughs, the mental map tends to orient northward—to gleaming laboratories in Boston, Basel, or Berlin. Yet, over the past decade, a quieter revolution has been underway in places rarely associated with cutting-edge biotechnology. From Dakar to Hyderabad, São Paulo to Cape Town, the Global South has cultivated vaccine innovation hubs that are not merely adapting imported science, but generating their own.

This shift didn’t happen by accident. Three interwoven forces have driven it: the urgent public health needs of low- and middle-income countries, the gradual decentralization of vaccine production technology, and a wave of scientists trained abroad who are returning home. Together, these trends are rewriting the geography of medical innovation.
