50% chance Oxford COVID-19 vaccine trial will yield ‘no result’

Due to a decline in infection rate, the team at Oxford University developing a COVID-19 vaccine believe that the chances of the trial yielding “no result” is now 50%, The Telegraph reported.

The University of Oxford last week announced that the advance human trial of the vaccine will involve up to 10,260 volunteers across the UK.

While explaining when the results of the trial will be available, the university said that to assess whether the vaccine works to protect from COVID-19, the statisticians in the team will compare the number of infections in the control group with the number of infections in the vaccinated group.

“It’s a race against the virus disappearing, and against time,” Professor Adrian Hill, director of the university’s Jenner Institute, told the Telegraph.

“We said earlier in the year that there was an 80 per cent chance of developing an effective vaccine by September. But at the moment, there’s a 50 per cent chance that we get no result at all.”

The professor told the newspaper that if fewer than 20 of the 10,000 volunteers in the trial test positive, the results may be useless.

However, Professor Andrew Pollard, head of the Oxford Vaccine Group, last week assured that “the clinical studies are progressing very well.”
