Nobel laureates are amongst scientists requiring volunteers to be exposed to coronavirus after getting a vaccine to see if it provides security.
In an open letter to the head of the United States National Institutes of Health, the group states so-called “obstacle trials” might speed up vaccine advancement.
The Oxford University Covid-19 vaccine programmes director said such research studies must be “informative and possible”.
There are now 23 coronavirus vaccines in clinical trials worldwide.
The only way we will know if any of them works is if enough volunteers are subsequently exposed to coronavirus in their every day life and do not get infected.
That might take well into next year, considered that many studies are being performed in countries where infection rates are falling.

The organisation 1 Day Sooner, consisting of more than 100 popular figures including 15 Nobel laureates, argues this should not be delegated opportunity.
It desires healthy young volunteers to be intentionally provided coronavirus after getting the vaccine, arguing that the threats to their health would be low, but the potential benefits to society enormous.
The letter states: “If obstacle trials can safely and efficiently speed the vaccine development procedure, then there is a formidable anticipation in favour of their use, which would need an extremely compelling ethical reason to conquer.”
The letter supporting challenge trials has actually been signed by Professor Adrian Hill, the director of the Jenner Institute at Oxford University which has among the leading prototype coronavirus vaccines.
He said human difficulty research studies could take place “in the coming months”.
Dr Francis Collins, director of the NIH, has actually said Covid-19 obstacle trials are “on the table for conversation – not on the table to start designing a plan”.
