Clincal trials could start next week on a potential new vaccine for Covid 19.
It's hoped it could be ready for use by September if it gets the go ahead.
It comes following a warning that social distancing measures could continue until a vaccine for coronavirus is available.
Professor Adrian Hill is the Director of the Jenner Institute at Oxford in England, where the vaccine is being developed.
He says normally it would take years to bring one to the market.
"We have a vaccine that we hope to start using in our first clinical trial as soon as next week.
"That has been made very rapidly by the Jenner Institute in Oxford, teams of people working together, hundreds of people involved in this effort, which is extraordinarily fast.
"Typically it would take five, maybe ten years to design and test a new vaccine, and bring it to use."
