World’s Leading COVID-19 Vaccine Trial Put On Hold Because Of ‘Unexplained Illness’

“Our standard review process was triggered and we voluntarily paused vaccination to allow review of safety data by an independent committee,” the company said in a statement on Tuesday. “This is a routine action which has to happen whenever there is a potentially unexplained illness in one of the trials, while it is investigated, ensuring we maintain the integrity of the trials.”“In large trials, illnesses will happen by chance but must be independently reviewed to check this carefully,” the statement said. “We are working to expedite the review of the single event to minimize any potential impact on the trial timeline. We are committed to the safety of our participants and the highest standards of conduct in our trials.”
The trial vaccine, jointly developed by pharmaceutical company AstraZeneca and scientists at the University of Oxford, was at the leading edge of an effort to develop a vaccine before the end of the year to fight the SARS-CoV-2 virus.
Health news site STAT said the vaccine’s Phase 3 trial was put on hold after a “suspected serious adverse reaction” to the drug in one participant in Britain.
“While the vaccine developers haven’t revealed the details of the potential adverse reaction, the company has downplayed fears, highlighting that trial suspension is a standard process, and can be triggered by a single medical event,” STAT reports. The individual in question is expected to recover, the site reported.
The process was moving so quickly that reports emerged last month that the vaccine might be granted an emergency use authorization by the Food and Drug Administration (FDA) as early as October, the Financial Times (FT) reported.
“The Trump administration is considering bypassing normal US regulatory standards to fast-track an experimental coronavirus vaccine from the UK for use in America ahead of the presidential election, according to three people briefed on the plan,” FT reported. “One option being explored to speed up the availability of a vaccine would involve the US Food and Drug Administration awarding ’emergency use authorisation’ (EUA) in October to a vaccine being developed in a partnership between AstraZeneca and Oxford University, based on the results from a relatively small UK study if it is successful, the people said.”
But Fortune reported that “AstraZeneca says it has held no discussions with the U.S. government about emergency authorization for the COVID-19 vaccine it is manufacturing.”
That vaccine is still undergoing late stage human clinical trials in several sites around the world, including in the U.K. and the U.S., making a rapid approval under the criteria the U.S. Food and Drug Administration has established so far a long shot.
Meanwhile, Russia said last month that it had approved a vaccine for COVID-19, becoming the first nation in the world to mark the achievement.
President Vladimir Putin, who announced the approval of the vaccine, said one of his two adult daughters has already been inoculated. Putin also said the vaccine underwent all tests to show its effectiveness, although Russian officials offered no data to back up his claim. The approval was granted by Russian health officials after just two months of human testing, Reuters reported.
