Research to find a way to deal with the coronavirus COVID-19 pandemic continues. Scientists in particular are predicting a possible new wave that is even more virulently infected, so it is important to predict what could happen … To do this, people who have already contracted COVID-19 have agreed to come back with to infect the virus. This is related to clinical studies of immune responses in former patients.

The clinical trials were published in a press release from Oxford University on May 19: A spokeswoman, Helen McShane, professor of vaccination science, said around 60 people between the ages of 18 and 30 have volunteered to be infected with COVID-19. All of them have the peculiarity of being sick with the virus during the pandemic.

How are you ?

It has been announced that the trials will be carried out in two phases, each carried out on 50% of the volunteers: the first step is to study and study the minimum dose that the virus can use to infect humans without causing symptoms . During the second stage, this minimum dose is then vaccinated into the second group of former patients.

In all cases, the volunteers are re-infected with the original strain (that of Wuhan). You will then be quarantined for two weeks in a special suite in the hospital. Everyone then benefits from strict and controlled medical follow-up care for one year. The aim is to track and study how the disease progresses, but more specifically how drugs and vaccines work against characters who have been re-infected with the virus.

Helen McShane said these clinical trials and follow-ups could help “design tests that can accurately predict whether people will be [réinfectées] are protected. “” This study has the potential to transform our understanding by providing high quality data, “added Shobana Balasingam, Senior Advisor Research Advisor at Wellcome Trust, the company that funds the tests used in the study. The researchers set so much hope in this study. We look forward to more results, especially the results!
