A British scientist has said at least two potential Covid-19 vaccines have already begun human trials while a number of other trials are fairly advanced, but a vaccine is still "months away" from coming on stream Professor James McInerney, Head of the School of Life Sciences at the University of Nottingham, said the genetic sequence of the coronavirus became known in January, which has enabled scientists to start examining possible vaccines.
Speaking on RTÉ's Morning Ireland, Prof McInerney said the current wave of the virus will be largely finished by the time a vaccine comes on stream and any vaccine would be about protecting people in the long term.
