LONDON (AP) British researchers testing an experimental vaccine against the new coronavirus are moving into advanced studies and aim to immunize more than 10,000 people to determine if the shot works.

Friday's announcement comes as Chinese scientists report promising hints from first-step safety tests of another vaccine candidate made in a similar way.

About a dozen potential vaccines are in early stages of human testing or poised to start.

Scientists have never created vaccines from scratch this fast and it’s far from clear that any will ultimately prove safe and effective.
