	Description:		In April 2020, epidemiologist-in-training Sophie Rose volunteered to be infected with the virus that causes COVID-19. As a young, healthy adult, she's offering to take part in a human challenge trial, a study where participants are intentionally exposed to SARS-CoV-2 to test vaccines and gather critical data. Explaining how challenge trials could speed up the development of effective vaccines, Rose shares why volunteering was the right decision for her.
