The UK government has signed a fourth coronavirus vaccine deal, securing up to 60 million doses of an experimental treatment being developed by drug giants GSK and Sanofi.
The government has already signed up for 100 million doses of the Oxford University vaccine being developed by AstraZeneca.
It has also secured another 90 million doses of two other promising vaccines.
However, it is still uncertain which, if any, of the vaccines may work.
Governments around the world have pledged billions of dollars for a COVID-19 vaccine and a number of pharmaceutical firms are in a race to develop and test potential drugs.
