A vaccine against coronavirus, developed by Oxford University in conjunction with pharmaceutical company AstraZeneca, has only a 50% chance of success, told the Telegraph the head of the project, in Oxford, Professor Adrian hill.

Hill said that producing a vaccine, the team encountered problems that may prevent them to create a vaccine against COVID-19 by September, as previously announced.

"At the moment there is a 50% probability that we will not get any results", – said the Director of the Jenner Institute at Oxford University’s Adrian hill, adding that earlier they talked about the 80% of possibility of success.

The Professor noted that due to the fact that the speed of propagation of the virus in the UK is declining and medical record less infected, the creators of the vaccine will probably not be able to use a sufficient number of volunteers for the next stage of tests of a vaccine against a new type of coronavirus. If COVID-19 will not apply, the volunteers will not be able to catch the virus that won’t allow scientists to estimate the effect of the new vaccine.

Developed at the Oxford vaccine COVID-19 began to be tested on humans since April 23. Later it became known that a partner of the research was the pharmaceutical company AstraZeneca. She received from the US government over a billion dollars to create a vaccine. American health Ministry had ordered 300 million doses.

It was reported that in June will become known the results of the first phase of clinical trials conducted in the UK. If they are successful, it will continue in other countries. If all goes according to plan, in September, the 30 million people in the UK, that is a little less than half of the population will be able to access the vaccine.
