Oxford researchers are seeking participants for a trial to discover what happens when people who have either already had Covid-19 or who have been vaccinated are exposed to the original strain of virus.

Researchers at the University of Oxford are looking for volunteers to take part in a human challenge trial to look at what kind of immune response can stop people from becoming infected with the original strain of the virus. The trial began in in April 2021 and the researchers are working with healthy young participants to study how the immune system responds to the virus.

A human challenge trial in medical research is a carefully controlled study that involves purposefully infecting a subject with a pathogen or bug, in order to study the effects of that infection.
