What if someone asked you to get infected with the COVID-19 virus, deliberately, in order to speed up the development of a vaccine? Would you do it? Would you risk your life to save others?

For months, dozens of companies have been racing to create coronavirus vaccines. Finally, three have done it. But according to the experts, we’re not out of the woods yet; we’ll need several vaccines to satisfy the global demand. One way to speed up the development process is a controversial technique called a human challenge trial, in which human subjects are intentionally infected with the virus. Senior correspondent Molly Webster gets the lowdown from Public News Service reporter Laura Rosbrow-Telem and then tracks down some of the tens of thousands of people who have volunteered to participate in a challenge trial.
