A vaccine for Covid-19 is seen as the way out to end the lockdowns that are crippling economies around the world - because easing lockdowns without a vaccine in place could see health services overwhelmed with coronavirus cases. But the big question is: when will a vaccine be ready?

A global race is happening right now to fast-track efforts to develop one. Among the teams involved is one from the Jenner Institute at the University of Oxford - they plan to start human trials of a vaccine in the coming days.

ITV News Science Editor Tom Clarke and ITV News Health Correspondent Emily Morgan spoke to Professor Adrian Hill, Director of the Jenner Institute at the University of Oxford. He told us about the trial he's involved in, and why he thinks it will be the first one to finish testing this summer, and - if all goes well - how GPs could be giving the vaccines to patients by the end of the year. He also explained why waiting for coronavirus cases to drop would actually harm efforts to quickly develop a vaccine. The Oxford trial is receiving funding as part of a government vaccine taskforce announced on Friday.
