Clinical trials have begun on new vaccines for the Corona virus, and all eyes of the world are installed towards the upcoming vaccine for the virus, which was announced by the World Health Organization according to various media sources.
According to the British newspaper, "The Guardian", 35 companies and academic institutions in the world are competing to produce a vaccine that can ward off the threat of the virus, also known as "Covid 19".
The newspaper said that 4 of these institutions have started vaccine tests that they have developed, including the American company "Moderna", which started clinical trials in humans.
For its part, the French "Sanofi" group announced that the drug "Blacknell", the anti-malarial drug that it produces, has demonstrated "promising" results in treating patients with the emerging coronavirus.
And thanks to the great speed of the arrival of drugs to the stage of human tests, the Chinese efforts in tracking the sequence of genetic material for the virus "Covid 19", according to Sky News Arabia reported on Saturday.
The CEO of the Alliance for Epidemic Innovations, Richard Hatchett, says the speed of "companies to produce an anti-coronavirus vaccine depends on their investment and an understanding of how to develop past vaccines against the previous Corona viruses."
The Maryland-based company, Novavax, says it will reuse the vaccines intended for these viruses to counter the emerging coronavirus, saying it has many volunteers who are willing to take clinical trials.
Although clinical trials seem to be an advanced stage for many, it is only the beginning, according to the newspaper, "The Guardian", which says that the clinical trials that were completed are only a preliminary point in order to obtain regulatory approval, which takes place in 3 stages.
The first stage includes testing the vaccine with a few dozen healthy volunteers, to monitor the positive and negative effects of the vaccine.
As for the second stage, it includes experiments on hundreds of people in several regions of the world, especially those affected by the virus, and studying the results very carefully.
After that, we will go to the third stage, which is testing the vaccine on thousands of volunteers around the world.
Of course, during these stages, many vaccines are excluded after, for example, they are confirmed to be ineffective or have harmful side effects, says Bruce Glen, who runs the human immunization program at the Sabine Vaccine Foundation in Washington.
Anielis Smith, professor of viral diseases at the London School of Tropical Medicine and Tropical Medicine, says that work to produce a vaccine is going very quickly, but that he will encounter many obstacles.
"Like most vaccine specialists, I don't think he's going to be ready for 18 months," he added.
The professor was commenting on US President Donald Trump's attempt to pass the vaccine before next November, the date for the US presidential election.
And not only that, once the drug is approved by the health authorities, there will be a challenge for the drug companies to produce large quantities of it that will satisfy the global demand for it.
Many of these companies do not have the production capacity to keep up with this demand, according to The Guardian
