Global share prices have surged on news of a second breakthrough coronavirus vaccine, following last week's positive results from Pfizer.
Interim data from the US firm Moderna suggests its vaccine is highly effective in preventing people getting ill and works across all age groups.
The news pushed shares in Moderna more than seven per cent higher in early trade.
It also lifted firms hit by the virus, with British Airways owner IAG rising 10 per cent and Cineworld up 13.5 per cent.
The UK's FTSE 100 share index closed about 1.6 per cent higher, while the main US indexes also climbed with the Dow Jones pumping 1.2 per cent and the S&P 500 increased 0.8 per cent.
