The World Health Organization (WHO) asserted that the vaccine against covid-19 developed by the pharmaceutical AstraZeneca it is the most advanced so far. The announcement was made today by the agency’s chief scientist, Soumya Swaminathan.
The UK-based company has already started clinical trials with the idea of - if successful – producing between 300 and 400 million doses starting later this year. Currently, some 10,000 people They 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. “pretty soon”.
On the other hand, the scientist mentioned 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 noted that the AstraZeneca option, developed by researchers at the University of Oxford and which has already been successfully tested on monkeys, “is more global in scope.”
Finally, the official explained that, in general, it takes from 8 to 10 years 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 fallen ill in the facilities.
After 28 days, the six macaques carrying the vaccine remained healthy. “The Rhesus macaque is the closest thing we have to humans,” said one of the researchers, Vincent Munster.
