Oxford's coronavirus vaccine triggers immune response

PanARMENIAN.Net - A coronavirus vaccine developed by the University of Oxford appears safe and triggers an immune response, the BBC reports.

Trials involving 1,077 people showed the injection led to them making antibodies and T-cells that can fight coronavirus.

The findings are hugely promising, but it is still too soon to know if this is enough to offer protection and larger trials are underway.

The UK has already ordered 100 million doses of the vaccine.

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.
