United Kingdom study on catching virus again

United Kingdom study on catching virus again”

The Reuters news agency said the study, which started on Monday, differs from challenge trials approved in February by medical regulator, which are being conducted by Imperial College London because they involve people who have not previously been infected with the virus.

"When we re-infect these participants, we will know exactly how their immune system has reacted to the first COVID infection, exactly when the second infection occurs, and exactly how much virus they got", McShane said.

The trial's initial phase will look at the minimum dose that allows the virus to start replicating without symptoms in some 50 per cent of volunteers. The second phase, which will be held during the summer, will involve people being given larger doses.

Researchers are looking for 64 healthy, previously Covid-infected volunteers from 18 to 30 years old to be studied under controlled, quarantined conditions for at least 17 days, the United Kingdom university said Monday.

Helen McShane, professor of vaccinology at the department of paediatrics, University of Oxford and chief investigator on the study, said: "Challenge studies tell us things that other studies can not because, unlike natural infection, they are tightly controlled".

The immune response needed to protect people against reinfection with the coronavirus will be explored in a new human challenge trial, researchers have revealed.

"First, we will define very carefully the baseline immune response in the volunteers, before we infect them". Their study will also look at the response of the immune system after getting reinfected with SARS-CoV-2.

Professor Helen McShane, the chief investigator, said: "Challenge studies tell us things that other studies can not because, unlike natural infection, they are tightly controlled".

The original strain of COVID-19 from Wuhan is going to be used because this is the one that scientists have the most information about, but another variant could also be included. Thereafter, the researchers will examine the participants in a quarantine unit for a minimum of 17 days.

For the phase-1 trial, the participants will undergo CT scans of the lungs and MRI scans of the heart.

"Keeping up the pace of scientific research and development, through crucial studies such as this remain the only way we will truly get ahead of this pandemic and bring it under control".

"Our new Antivirals Taskforce will seek to develop innovative treatments you can take at home to stop COVID-19 in its tracks", Johnson said.

The research will last for a total of 12 months, with eight follow-up appointments following discharge.

Meanwhile, critics of the human challenge trials have pointed out the ethical dangers of infecting people without being sure of its long-term consequences.

"There are still many unknowns surrounding this virus and human infections studies can enable us to learn a lot about Covid-19".

The ultimate aim is to design better treatments and vaccines.

"If we can determine. that a certain level of antibodies means it's not possible to reinfect somebody, that would feed very immediately into designing the most effective vaccines", Helen McShane, the study's lead scientist and a professor of vaccinology at the University of Oxford's Department of Paediatrics is quoted in the report as saying.
