What are human challenge trials. This is where volunteers are purposefully exposed — “challenged” — by a pathogen in controlled conditions. By doing this, you can rapidly test the immune response, vaccines, and treatments without the need to wait for infections out in the wild. One slight problem- volunteers can die when you don’t have a good treatment! Should they be done?
This is the challenge of medicine. Balancing the risks in order to gain knowledge. It’s complicated.
