Vaccine Inequities and the Legacies of Colonialism: Speculative Fiction’s Challenge to Medicine

New vaccines to prevent COVID-19 and malaria underscore the importance of scientific advances to promote public health globally. How is credit for such scientific discoveries attributed, and who benefits? The complex narrative of Amitav Ghosh’s The Calcutta Chromosome , both historical and speculative, demonstrates how medicine has come to value particular kinds of advances over others, prompting readers to question who controls access to resources and at what cost to global populations. In Ghosh’s imagined world, scientific discovery is evaluated and rewarded—and ultimately deemed necessary—for its ability to serve communal, public health needs.
