The World Health Organization (WHO) assures that the Covid-19 vaccine developed by the pharmaceutical company AstraZeneca is the most advanced of all the experiments carried out in the world to date.
The claim The WHO did it through the voice of the organism's chief scientist, Soumya Swaminathan.
The company, based in the United Kingdom, has already started to carry out clinical tests with the idea that, if these are to be successful, it will begin to produce between 300 and 400 million doses from the end of this year.
Currently, about 10,000 people are participating in a large-scale clinical trial, and an additional trial with 30,000 volunteers is planned for the end of the month.  "Certainly, in terms of how advanced they are, and the stage they are in, I think they are probably the main candidates," said Swaminathan, who expressed confidence in the possibility of having favorable results "quite pro nto. ”
Besides, the scientist said that the coronavirus vaccine developed by the American modern biotechnology company“ is not very far ”from the British company, among more than 200 candidates. In this case, the firm "will enter phase three of clinical trials probably from mid-July," added the WHO representative.
However, Swaminathan stressed that the AstraZeneca option, developed by researchers from the Oxford University, which has already been successfully tested in monkeys, “has a more global reach.”
Finally, the official explained that, in general, it takes 8 to 10 years to bring a vaccine to the market. However, the WHO acceleration project aims to shorten vaccine development to an "unprecedented" period of 12 to 18 months.
In March, Oxford scientists inoculated six Rhesus macaques in a single dose in a laboratory . Subsequently, the animals were exposed to large amounts of the SARS-CoV-2 virus, with which other monkeys had already become ill in the facilities.
At 28 days, the six macaques carrying the vaccine remain healthy. "The Rhesus macaque is the closest thing we have to humans," said one of the researchers, Vincent Munster.
