Young people between the ages of 18 and 30 were recruited by Oxford University to conduct an experiment. They had been infected with Covid-19 and will be voluntarily re-exposed to it, in order to learn more about how immunity works.
There will be 64 volunteers. The starting plan is expose them to the original strain of Covid-19, but the idea of introducing variants is not excluded by the researchers. Scientists will have all the data in hand: quantity of virus, exact date of exposure, etc. And will be able to analyze the reactions of each person’s immune system.
17 days in hospital
The circumstances of the experiment will be as follows: the volunteers will be quarantined for 17 days in a hospital. Their state of health will obviously be closely monitored. If they develop symptoms, they will receive a treatment based onmonoclonal antibodies. Each will receive the sum of 5,000 pounds.
In addition to advancing knowledge about the immune system’s defenses during a second infection and better understanding until when it is possible to be infected again, the study will help fill in the unknowns in terms of treatments and improve vaccines.
