Human challenge trials for covid-19 have been discussed since the early days of the pandemic. But only Britain has allowed them to go ahead
Human trials are a valuable part of medical research. Studying sick people in the controlled environment of a lab allows scientists to collect valuable information about how diseases work much more quickly than relying on messy and uncertain data from the real world. Since the second world war, around 40,000 volunteers have allowed themselves to be infected with everything from malaria and typhoid to dengue fever and cholera.
Another strand of the trial aims to nail down just how long it takes, after an individual is infected, for covid-19 to be detected, both by cheap, widely used lateral-flow tests, and by more expensive, more accurateones. During the trial, researchers conducted frequent swabs of the rooms that volunteers were confined to. That allowed them to figure out exactly when infectious viral particles—as opposed to just passive blobs of genetic material—were present in the room.
