The UK government has signed deals for 90 million doses of promising coronavirus vaccines that are being developed.
The vaccines are being researched by an alliance between the pharmaceutical companies BioNtech and Pfizer as well as the firm Valneva.
The new deal is on top of 100 million doses of the Oxford University vaccine being developed by AstraZeneca.
However, it is still uncertain which of the experimental vaccines may work.
A vaccine is widely seen as the best chance of getting our lives back to normal.
Research is taking place at an unprecedented scale – the world became aware of coronavirus at the beginning of the year, but already more than 20 vaccines are in clinical trials.
Some can provoke an immune response, but none has yet been proven to protect against infection.
