A coronavirus vaccine trial by University of Oxford researchers aims to get efficacy results by September, and manufacturing is already underway.
A team led by Sarah Gilbert, a professor of vaccinology, has recruited 500 volunteers from the ages of 18 to 55 for the early- and mid-stage randomized controlled trial. It will be extended to older adults and then to a final stage trial of 5,000 people. Gilbert said that the timing is ambitious but achievable.
“We would hope to have at least some doses that are ready to be used by September,” she said in an interview. “There won’t be enough for everywhere by then, but the more manufacturing we can do starting from now, then the more doses there will be.”
The world’s biggest trial of drugs to treat Covid-19 patients has been set up in the UK at unprecedented speed, and hopes to have some answers within weeks.
The Recovery trial has recruited over 5,000 patients in 165 NHS hospitals around the UK in a month, ahead of similar trials in the US and Europe, which have a few hundred.
“This is by far the largest trial in the world,” said Peter Horby, professor of emerging infectious diseases and global health at Oxford University, who is leading it. He has previously led Ebola drug trials in west Africa and the Democratic Republic of the Congo (DRC).
The Recovery team expects to be the first to have definitive data. “We’re guessing some time in June we may get the results,” said Prof Horby. “If it is really clear that there are benefits, an answer will be available quicker.” But he warned that in the case of Covid-19, there would be no “magic bullet”.
