The world health organization (who) announced that at the moment the world is created not less than 70 potential vaccines against coronavirus, the development of three of them is under clinical trials. It is reported by RIA Novosti.
Closest to the vaccine approached the company CanSino Biologics Inc. Beijing Institute of biotechnology, whose vaccine is already approved for testing in humans and is the second phase of clinical verification.
American company Moderna Inc. and Inovio Pharmaceuticals Inc. have also made significant progress in the development of vaccines, despite the fact that neither one of them had not engaged in creation of such preparations. It is noted that in both cases, firms skipped the stage of animal testing, which in other cases is mandatory, and immediately moved on to tests on humans.
In vaccine development to participate as research centers from around the world and the largest pharmaceutical company. However, a serious obstacle to preventing the spread of coronavirus is not only development funds, but its production in industrial scale. Many influential players of the pharmaceutical market, with significant capacity for such production, such as Pfizer Inc., Johnson &Johnson and Sanofi, are dealing with the issue of the vaccine.
Who said that it is planned to develop a vaccine against coronavirus for a year and a half, while on average, the creation of a new vaccine and release it to the market requires 10-15 years. These rates are explained by the fact that the deadly virus while there is no cure.
Many experts have expressed concern that such a rapid development of vaccines can carry some risks. For example, one such risk could be the effect of “immune enhance”, which is that the vaccine, by contrast, interferes with the immune response.
At the moment the world’s been more than two million cases of infection with coronavirus. In total more than 130 thousand people died in the pandemic.
