Smallpox, steamships, and two port cities
Brabin compares Boston and Liverpool's 1901–5 smallpox epidemics, arguing steamship traffic linked peak US incidence to Liverpool while Hope and Durgin used surveillance, isolation and ring vaccination later reused in global eradication.

An Analysis of the United States and United Kingdom Smallpox Epidemics (1901-5) - The Special Relationship that Tested Public Health Strategies for Disease Control
What they did
A comparative historical analysis of the US and UK smallpox epidemics of 1901–5, especially Boston and Liverpool, using public-health reports, port records, and accounts of Medical Officers Hope and Durgin, including anti-vaccination politics.
What they found
After 1860, rapid steamers guaranteed transatlantic smallpox passage. Incubating travellers delayed recognition. Despite 1901 contact between Liverpool Port Authority and the USPHS, maritime surveillance was not heightened. Both cities used screening, isolation, quarantine, contact tracing and ring vaccination; Boston's anti-vaccinationists were especially vehement. Liverpool's post-exposure vaccination helps explain a rapid 1903 fall.
The limits
What it doesn't show
This is not a modern vaccine RCT. Historical protective-effect inferences from Liverpool data are not a new serological survey of 1901 populations.
Key terms
- Ring vaccination
- Selective vaccination of contacts living near cases, later used in WHO smallpox eradication.
- Incubating travellers
- Infected persons not yet showing disease, who seeded port epidemics after steamship arrival.
- Edward William Hope
- Liverpool Medical Officer of Health during the epidemic, counterpart to Boston's Samuel Holmes Durgin.
- Transatlantic steam traffic
- Post-1860 rapid passage that made US–UK smallpox transfer routine.

Common questions
Which cities are paired?
Boston and Liverpool, both large ports with late recognition of incubating cases.
What is ring vaccination here?
Selective vaccination around cases, later used in global eradication.
Was maritime surveillance stepped up in 1901?
Despite communications, there is no record of heightened surveillance in either city or country.
