Oxford scientists claim 1 million doses of coronavirus vaccine by Sept; regulatory filings say May, 2021
ChAdOx1 is the fourth COVID-19 vaccine candidate in the world to undergo clinical trial phase

Scientists at Oxford University have claimed they will be able to come up with a vaccine for coronavirus by September this year even though the regulatory filings indicate otherwise. The estimated study completion date for Oxford University's drug candidate ChAdOx1 is May 2021, as per the filings.

Randomised clinical trials of 510 participants is scheduled to begin in April, 2020. "The Phase I/II study is meant to Determine 'Efficacy, Safety and Immunogenicity of the Candidate Coronavirus Disease (COVID-19) Vaccine ChAdOx1 nCoV-19 in UK Healthy Adult Volunteers," the filing says.

Earlier, WHO health experts had indicated that a possible coronavirus vaccine was at least 18 months away-September, 2021.

Lead researcher of the vaccine development programme, Prof Sarah Gilbert, at a press conference on Friday, said that she and her team were confident that ChAdOX1 vaccine can work against the coronavirus. The group has promised that they will make one million vaccine doses available by September.

The ChAdOx1 is the fourth COVID-19 vaccine candidate in the world which has entered the clinical trial phase of vaccine development. What's different about the ChAdOx1 is that will take significantly less time than other vaccine candidates to be delivered in mass quantities.

The other three vaccine candidates have been proposed by two US groups and one Chinese group, it is expected to take at least 12 to 18 months to mass produce these vaccines.

Gilbert said her team had been working on a Disease X, a name "given to an unknown disease which was going to come and cause a pandemic in future, and we needed to plan for it."

"With ChAdOx1 technology, already 12 clinical trials have been conducted against different diseases; we consistently see a very good vaccine safety and very strong immune response with single dose, while some other vaccine technologies such as RNA and DNA need two or more," added Gilbert.

Oxford group confident about trail phase

Scientists at Oxford are so confident about the vaccine working that they have already started producing it even before the clinical trial phase. Professor Adrian Hill said that the team has started production early because they didn't want to reach a stage in September when trials were finished but they didn't have a vaccine ready for distribution.

"We have started at-risk manufacturing this vaccine, not on a small scale but with a network of seven manufacturers in different places across the world," said Hill.

Clinical Trial Phase

The three-phase trial will start with 510 volunteers and will expand as 5,000 more volunteers join in the third phase.

"I have worked on this technology a lot and I have worked on MERS vaccine trails and I have seen what it can do, and I think it has a very strong chance of working," Prof. Gilbert said.

Gilbert's team was awarded a 2.2 million pounds grant from the UK's National Institute for Health Research and the UK Research and Innovation earlier this year to scale up its work.
