Moderna’s vaccine is safe and 94% effective, regulators say, clearing the way for US emergency authorisation.
If it is approved by the Food and Drug Administration’s (FDA) vaccine panel, it could become the second coronavirus vaccine to be allowed in the US.
It comes one day after Americans across the country began receiving jabs of the Pfizer-BioNTech vaccine.
Unlike the Pfizer vaccine, the Moderna shot does not require ultra cold storage during shipping.
Moderna’s data was released by the FDA on Tuesday, ahead of the vaccine panel’s meeting to discuss the drug on Thursday.
