Researchers at the University of Oxford, UK, which are developing a Corona19 vaccine, said that the likelihood of developing the vaccine in September, which was originally set as a goal, fell by half.

Professor Hill, director of the Jenner Institute at Oxford University, said in an interview with British media, "We are going to conduct clinical trials on 10,000 applicants, but the spread of Corona19 is slowing and may not produce meaningful results."

Professor Hill, who is developing vaccines in collaboration with pharmaceutical company AstraZeneca, is conducting clinical trials of vaccine candidates, Reuters said.

"If corona19 does not spread, vaccine applicants will not become ill," said Hill. "In this case, scientists can't figure out if there is any significant difference in vaccine administration.

"Vaccine development is a fight against viruses and time."

In addition to the UK, there are 8 corona19 vaccines in clinical trials worldwide, including China in China, 2 in the US, and 1 in Germany. It is said that.
