Moderna is filing for US and European emergency regulatory approval of its coronavirus vaccine so that it can be recommended for widespread use.
Regulators will look at trial data for the mRNA vaccine and decide if it is safe and effective enough to recommend for roll out.
Clinical studies show the jab is more than 94% effective at protecting people from becoming ill with Covid-19.
Pfizer, which has a similar jab, has already filed for the same US approval.
