How COVID-19 human challenge trials work -- and why I volunteered | Sophie Rose · 6:35 · Video: TED · Watch at the source

In short: In April 2020, Sophie Rose volunteered for a human challenge trial. This video explores how intentionally exposing healthy participants to SARS-CoV-2 can accelerate vaccine development and provide critical data.

A human challenge trial involves intentionally exposing healthy participants to a pathogen, such as the virus that causes COVID-19, to test vaccine efficacy and gather essential data. Sophie Rose, an epidemiologist-in-training, explains the mechanics of these trials and her personal decision to participate as a young, healthy adult.
