Oxford and AstraZeneca resume COVID-19 vaccine trials

LONDON (AP) – Oxford University announced on Saturday that it was launching a trial for a coronovirus vaccine, which is developing with pharmaceutical company AstraZeneca, a move that comes days after the study was conducted in a UK The patient was suspended after a reported side-effect.

In a statement, the university confirmed its resume at all UK clinical trial sites, as regulators gave a pause on Sunday.

“The independent review process has concluded and both the independent safety review committee and the UK regulator, following the recommendations of MHRA, will recommend testing in the UK,” it said.

The vaccines being developed by Oxford and AstraZeneca are widely considered to be among the strongest contenders among dozens of coronavirus vaccines at various stages of testing worldwide.

British Health Secretary Matt Hancock welcomed again, Saying in a tweet It was “good news for all” that the test is “back up and running”.

The university said in such large trials “it is expected that some participants will become unwell and every case must be carefully evaluated to ensure a careful assessment of safety.”

It said that some 18,000 people globally have received the vaccine so far. Volunteers from some of the worst affected countries – Britain, Brazil, South Africa and the US – are participating in the trial.

Brazilian health regulator Anvesha said on Saturday that it had approved the resumption of trials of the “Oxford vaccine” in the South American country after receiving official information from AstraZeneca.

Although the Oxford participant would not disclose information about the patient’s illness due to confidentiality, a spokesperson for AstraZeneca said earlier this week that a woman had developed severe neurological symptoms that led to stagnation. In particular, the woman is said to have symptoms that develop transverse myelitis, a rare inflammation of the spinal cord.

The university stressed that it is “committed to the safety of our participants and the highest standards of conduct in our study and will continue to monitor closely.”

Interruptions in drug trials are common and temporary holdings led to a sharp decline in AstraZeneca’s stock price after Tuesday’s announcement.

The Oxford-AstraZeneca study was previously halted in July for several days following neurological symptoms developed by a participant, an unknown case of multiple sclerosis that researchers said was unrelated to the vaccine.

During the third and final phase of testing, researchers look for any signs of potential side effects that may have been undefined in earlier patient research. Due to their large size, studies are considered to be the most important study phase to lift less common side effects and establish safety. The test also finds out who is sick and who is not between the vaccine patients and those receiving dummy shots.

A lecturer in intensive care medicine at the University of Cambridge, Drs. Charlotte Summers said the halt was an indication that the Oxford team had previously been putting up security issues, but that “there was much speculation.”

“To deal with the global COVID-19 epidemic, we need to develop vaccines and treatments that people feel comfortable using, so it’s important to maintain public confidence that we stick to the evidence and have information available Do not conclude before, ”she said.

Scientists and others around the world, including experts from the World Health Organization, have sought to keep a lid on the expectation of imminent success for coronovirus vaccines, saying vaccine testing is rarely straightforward.

Italy’s Minister of Health, Roberto Speranza, welcomed the reinstatement of the vaccine test, but warned that discretion is still necessary.

“Science is at work to deliver efficient and safe treatment and vaccines to the world,” he said. “Meanwhile, the key continues to be our behavior.”

Italy, which was void for the outbreak of Europe, is one of the main countries to invest in the AstraZeneca vaccine.

Two other vaccines are in large, final-stage trials in the United States, one by Modern Inc. and the other by Pfizer and Germany’s BioNtech.
