Researchers at the University of "Oxford" in Britain revealed that the vaccine being developed for the emerging corona virus showed "promising results".
The experiments of the first stage showed that blood samples taken from volunteers revealed that the vaccine stimulated the body to produce antibodies, in addition to what are known as "T cells", which are found in the blood and are an essential component of the human immune system.
And the British "Sky News" network quoted the Chairman of the Research Ethics Committee in Parkshire, which gave "Oxford" the green light to start its experiments, David Carpenter, as saying that the working group to develop the vaccine is on the right track.
Carpenter added: "It is difficult to set a precise date for launching the vaccine, as things may change suddenly, but through the progress of work until now, we can say that the vaccine will be available next September, a goal that scientists focus heavily on."
He added: "The vaccine will be given first to the most needy groups in society, such as the elderly and health care workers, and nurses and pharmacists will also be allowed to give the vaccine to those who require it."
The CEO of the drug giant Astra Zenica, which is cooperating with Oxford scientists in producing the vaccine, said last month that the first stage of testing was nearing completion, and that the third phase had begun, promising to give the vaccine thousands to be tested on a large scale, And effectively check its safety.
And AstraZeneca reached agreements to supply nearly two billion doses of vaccine around the world, even before its launch and final verification of its effectiveness.
The Oxford vaccine is based on experiments that test weak copies of the common cold viruses that cause inflammation in chimpanzees. It also contains the genetic material of the SARS Cove-2 protein, the strain that causes the Covid-19 epidemic.
The Oxford University vaccine is one of more than 100 vaccines under development to combat the coronavirus, which has infected more than 13 million people worldwide, and has killed at least 582,000 people.
