'I'm cautiously optimistic': Imperial's Robin Shattock on his coronavirus vaccine

Team is using new approach that could be cheap and scalable and become the norm within five years

Prof Robin Shattock would have liked slightly longer to develop the revolutionary approach to vaccines that he is pretty sure will not only save lives in the Covid-19 pandemic but become the norm for vaccine development within five years.

His team at Imperial College were working on Ebola and Lassa fever vaccines using new technology but had not got as far as human trials when a novel coronavirus started to kill thousands of people in Wuhan, China.
