Brits' Plan in 1788 to Stop Smallpox May Have Backfired

A 2026 study estimates that up to 220,000 Indigenous Australians died in Sydney’s 1789 smallpox epidemic, triggered by exposure from the First Fleet. Coverage highlights how British doctors may have inadvertently introduced the virus through variolation—a controlled inoculation method using infected scabs—despite its intended purpose of preventing smallpox. The outbreak’s scale and rapid spread, modeled in recent research, underscore the unintended consequences of colonial-era medical practices on Indigenous populations.

Multiple outlets—including *Nature*, *The Conversation*, and *Smithsonian Magazine*—cite stochastic modeling and historical records to connect the epidemic’s origins to the First Fleet’s arrival. The findings emphasize how variolation, though used to curb smallpox in Britain, likely facilitated the disease’s introduction to Australia, where Indigenous communities had no prior immunity. Discussions also note the broader impact on global health history, framing the event as a pivotal example of colonial-era biological exchange.

Watch for further analysis on how this research may reshape historical narratives of British colonization and its health legacies. Coverage does not yet specify whether new archaeological or genetic evidence will emerge to corroborate the findings, but debates over colonial responsibility and medical ethics are likely to intensify. Indigenous communities and historians may also push for acknowledgment of the event in national commemorations or reparations discussions.
