But only the U.K. has pushed ahead with Covid-19 challenge trials, deliberately infecting volunteers to study a new, sometimes-deadly disease that still harbors many unknowns.

On March 8, 23-year-old Jacob Hopkins, a U.K. university student, watched researchers enter his quarantine room’s airlocked entrance at London’s Royal Free Hospital. They wheeled a cart carrying a big red box, like a picnic cooler, labeled “biohazard.”

Planning started in April 2020, led by researchers from the University of Oxford and Imperial College London, officials from the government-appointed U.K. Vaccine Taskforce, and a small London-based biotech called hVivo Services Ltd. that specializes in contract drug testing….
