The University of Oxford's possible COVID-19 vaccine could be rolled out by the end of the year but there is no certainty, the lead developer of the vaccine said on Tuesday. "The end-of-the-year target for getting vaccine rollout, it's a possibility but there's absolutely no certainty about that, because we need three things to happen," Sarah Gilbert told BBC Radio. "The chances of us getting a vaccine before Christmas that actually is highly effective are, in my view, very low," Whitty told lawmakers. The Oxford scientists had eyed a million doses of the potential vaccine to be produced by September. There are no approved vaccines yet for COVID-19, but the World Health Organization has said AstraZeneca's shot is one of the leading candidates.
