The Oxford University team responsible for developing a vaccine against coronaviruses said that a drop in the rate of infection would make it increasingly difficult to prove its success, reported the Telegraph.
“This is a race against the disappearance of the virus and against time,” Professor Adrian Hill, director of the university’s Jenner Institute, told the newspaper. “We said earlier this year that there is an 80% chance of developing an effective vaccine by September. But right now, there’s a 50% chance that we won’t get any results. “
Hill said he expects fewer than 50 of the 10,000 people who volunteered to test the vaccine trial next week to catch the virus. If fewer than 20 tests are positive, the results may be useless, the newspaper said.
Although developers around the world are working on up to 100 experimental vaccines for Covid-19, the process is likely to take some time. Finding a vaccine and distributing it around the world will be a “huge moonlight,” said Dr. Michael Ryan, executive director of the World Health Organization’s emergency program earlier this month. It is possible that the disease ishere to stay, he said.
The British government has agreed to pay up to 100 million doses, adding that 30 million could be ready by September. The daily rate of new infections has dropped by almost two-thirds since it peaked at nearly 9,000 on April 10.
Reuters has also said that Oxford University could joinModerna in a large-scale testing program in July.
