Hill said the vaccine development team has problems that could prevent them from developing the vaccine against COVID-19 by September, as previously announced.”Currently, there is a 50 percent chance that we will not achieve any results at all,” he insisted, adding that they had previously talked about an 80 percent chance of success.
The professor noted that due to the fact that the spread of the virus in the UK is declining and doctors are registering less and less infected, the creators of the vaccine will probably not be able to use enough volunteers for the next stage of testing the new coronavirus vaccine.
If COVID-19 does not spread, volunteers will not be able to encounter the virus, which will not allow scientists to evaluate the effect of the new vaccine.
The vaccine, which is being developed in Oxford, has been tested in humans since April 23.
The results of the first phase of clinical trials conducted in the UK are expected to be announced in June. If they are successful, they will continue in other countries.
If all goes according to plan, in September 30 million people in Britain, that is, a little less than half of the population, will have access to the vaccine.
