LARGE trials are underway to determine if a vaccine created by Oxford University is enough to protect against the corona virus.
The BBC reported that tests already done on 1,077 people showed they were making antibodies and T-cells that can fight Covid-19, which was promising.
Britain has already ordered 100 million doses of the vaccine.
The vaccine – called ChAdOx1 nCoV-19 – 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.
This means the vaccine resembles the coronavirus and the immune system can learn how to attack it.
