Oxford Covid-19 Vaccine Is Safe and Promising

An University of Oxford group and the British-Swedish pharmaceutical company AstraZeneca reported Monday that their coronavirus vaccine candidate, on which the U.S. and European governments have placed substantial bets , was shown in early stage in  human trials to be safe and stimulate a strong immune response .
Trials involving 1,077 people showed the injection led to them making antibodies and T-cells that can fight corona virus .
The vaccine - called ChAdOx1 nCoV-19 - is being developed at unprecedented speed. It is made from a genetically engineered virus that cause 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 corona virus .
There were no dangerous side-effects from taking the vaccine, however, 70% of people on the trial developed either fever or headache.
The researchers say this could be managed with Paracetamol .

Prof Sarah Gilbert, from the University of Oxford, UK, says: "There is still much work to be done before we can confirm if our vaccine will help manage the Covid-19 pandemic, but these early results hold promise ."

The results so far are promising, but their main purpose is to ensure the vaccine is safe enough to give to people .

More than 10,000 people will take part in the next stage of the trials in the UK.
However, the trial has also been expanded to other countries because levels of coronavirus are low in the UK, making it hard to know if the vaccine is effective.
There will be a large trial involving 30,000 people in the US as well 2,000 in South Africa and 5,000 in Brazil . Because Brazil is now hotspot of corona virus .
