Watch: Moderna's vaccine achieves high results

Moderna announced that its experimental Covid-19 vaccine 'mRNA-1273' was 94.5 per cent effective in preventing coronavirus. The statement was issued on the basis of interim data from a late-stage clinical trial.

The announcement makes Moderna the second US-based pharmaceutical giant to have reported exceedingly hopeful results from clinical trials of their respective coronavirus vaccine candidates. Just earlier this month, pharma giant Pfizer announced that its Covid-19 experimental vaccine was shown to be more than 90 per cent effective.
