The Medicines and Healthcare products Regulatory Agency (MHRA) has authorised the Moderna vaccine following months of clinical trials involving tens of thousands of people.
The vaccine is proved to be 94% effective in preventing disease, including in older people. The Government has agreed to purchase 10m doses of the Moderna vaccine in addition to its previous order of 7m, taking the total to 17m.
The Moderna jab will not be available until the spring, but it gives the authorities more time to set clear policy for its delivery. In the meantime, the NHS is working hard to give the Pfizer and AstraZeneca vaccines to priority groups. It will, however, be weeks and months until the NHS feels the benefit of the vaccination programme.
