Given that the number of infections have been falling - ONS estimate that 39,000 people were infected at any one time during the last two weeks of May; less than one in a thousand - how do the researchers know that participants have come in to contact with those with the disease?
Unless they place them in close contact with those known to have the virus? I don't think they do.

Not enough of the virus in the UK for testing.
The Oxford group are trialing it with health care workers in Brazil now. They are on the front line currently. The will continuously have to chase the virus for testing the vaccines are the virus fizzles out from place to place. Infection tends to peak before it is even noticed in an area due to time between catching it and getting symptoms and getting symptoms and going to hospital and going to hospital and dying. These lags must make it hard for them to work out where to test the vaccines. |

Ok, thanks.
As far as I'm aware, in the UK, participants are volunteers of no particular occupation who just go about their daily business. |
