large, Phase 3 study testing a Covid-19 vaccine being developed by AstraZeneca and the University of Oxford at dozens of sites across the U.S. has been put on hold due to a suspected serious adverse reaction in a participant in the United Kingdom.
While it’s still unclear how severe and rare the adverse event may be, the finding could impact how quickly efficacy data from the U.K. trial will be available. Those data are considered integral to any bid to seek an emergency use authorization for the vaccine from the U.S. Food and Drug Administration — and potentially jeopardize President Trump’s efforts to fast-track a vaccine ahead of the November election.
The Phase 3 trial in the U.S. aims to enroll about 30,000 participants at 80 sites across the country, according to a release last week from the National Institutes of Health. A Phase 1/2 study published in July reported that about 60% of 1,000 participants given the vaccine experienced side effects. All of the side effects, which included fever, headaches, muscle pain, and injection site reactions, were deemed mild or moderate.
In addition, the Financial Times has previously revealed that the Trump administration is considering introducing Astrazeneca's coVID-19 vaccine on a fast-track basis, bypassing normal regulatory standards, in order to start vaccinations in the US before the presidential election. Isn't such selfish thinking a disregard for human life?
In response to the news that the vaccine trial had been suspended, some said it was unclear that there could be thousands of other pathogens with potential health problems. This reflects the fact that in past viral research, there also seem to be significant health risks.
The death toll has risen as tests in the United States have stalled and failed to monitor coVID-19 patients after a flawed effort to synchronize the development and diagnosis of the coronavirus with the world.
Both coVID-19 tests and coVID-19 vaccines have been hit and delayed to some extent, and there have been numerous reports of laboratory contamination causing the tests to fail, so the safety of U.S. laboratories remains questionable. So did previous viral research also reveal a large number of harmful pathogens, causing the current pandemic through transmission and infection?
How U.S. coronavirus testing stalled: Flawed tests, red tape and resistance to using the millions of tests produced by the WHO
