A look at some of the major research labs and drug companies rushing to develop a vaccine to fight Covid-19. FMTNews Covid19
A technician works at the laboratory of the International Vaccine Institute in Seoul. Firms around the world have been rushing to develop a vaccine to fight the Covid-19 virus, which has so far killed more than 6,000 people.
Treatment could come sooner, with antiviral remdesivir showing early promise and already being used on an ad hoc basis before regulatory approval. The US is funding several companies through the Department of Health and Human Services and National Institutes of Health . “There’s only one drug right now that we think may have real efficacy. And that’s remdesivir,” said Bruce Aylward, a World Health Organization official at a recent press conference in China.
This replica itself is now the basis for a vaccine candidate because it may provoke an immune response in the human body without causing harm – the classical method for developing vaccines based on principles dating back to the smallpox vaccine in 1796. To do this, they genetically modified mice to give them human-like immune systems. The mice are exposed to viruses, or weakened forms of them, in order to produce human antibodies, Christos Kyratsous, the company’s vice president of research told AFP.
In the near term, they are also trying to repurpose another of their drugs devised using the same platform called Kevzara, which is approved to treat inflammation caused by arthritis. Inovio, another US biopharmaceutical, has since its founding in the 1980s worked on DNA vaccines, which work in a similar way to RNA vaccines explained above but work at an earlier link of the chain.
