The vaccine - called ChAdOx1 nCoV-19 - is being developed at unprecedented speed.It is made from a genetically engineered virus that causes the common cold in chimpanzees.
It has been heavily modified, first so it cannot cause infections in people and also to make it "look" more like coronavirus.
Scientists did this by transferring the genetic instructions for the coronavirus's "spike protein" - the crucial tool it uses to invade our cells - to the vaccine they were developing.
This means the vaccine resembles the coronavirus and the immune system can learn how to attack it.
