Moderna’s Covid-19 vaccine becomes second to receive FDA approval

The US medicines regulator has authorised the use of Moderna’s Covid-19 vaccine on an emergency basis, making a second jab available and boosting supplies at a critical crunch point as several states complain they cannot secure enough shots. The second emergency use authorisation for a Covid-19 vaccine will mean that more than 5.9m Moderna shots will be delivered in the coming week. Moderna said about 20m doses would be delivered to the US government by the end of the year. In the first quarter of next year, the company now expected to have between 100m and 125m doses available, of which 85m-100m will be in the US.
