Research that deliberately infected healthy volunteers with the SARS-CoV-2 virus was published Thursday in the journal Nature Medicine.
That's just one of the findings from research that deliberately infected healthy volunteers with the SARS-CoV-2 virus. The findings were published Thursday in the journal Nature Medicine.
Challenge studies can be controversial because they involve intentionally giving someone a virus or other pathogen in order to study its effects on the human body. Even with safeguards in place, there's an element of risk, particularly when studying a new virus.
But they are also hugely valuable for understanding the course of an infection.
"Really, there's no other type of study where you can do that, because normally, patients only come to your attention if they have developed symptoms, and so you miss all of those preceding days when the infection is brewing," said lead study author Dr. Christopher Chiu, an infectious disease physician and immunologist at Imperial College London.
