Pharmaceutical company AstraZeneca halted global testing of its coronavirus vaccine on Tuesday due to a serious adverse reaction in a participant, the company said.

The end of the trial, which was first reported through Stat News, will allow the Anglo-Swedish company to conduct a protection review. The length of the retention is unclear.

In a statement, the company described the closure as a “routine action that will have to happen whenever there is a potentially unexplained illness in any of the trials, while you are undergoing treatment. Investigation, ensuring that we maintain the integrity of the trials . . “

In giant trials such as those monitored through AstraZeneca, the company said, participants are in poor health by chance, but those situations “need to be reviewed independently to determine this carefully. “

The company said it “is running to accelerate the review of the bachelor occasion to minimize any possible effect on the testing schedule” and that it is “committed to protecting our participants and standards. Highest driving functionality in our tests. ” ”.

A user familiar with the situation and who spoke on condition of anonymity said that the player has been entered for a Phase 2/3 test in the UK. The individual also said that a trial volunteer in the UK had transverse myelitis, an inflammatory syndrome that affects the spinal cord and is triggered through viral infections. However, the timing of this diagnosis and its direct link to the AstraZeneca vaccine is unclear.

AstraZeneca’s vaccine, known as AZD1222, is based on a chimpanzee adenovirus that has been modified to carry coronavirus genes and into human cells. Although the adenovirus is thought to be harmless, the coronavirus parts of the vaccine are intended to elicit a protective immune reaction that would be activated if the coronavirus itself were to attempt to infect a vaccinated individual.

However, adenoviruses can cause their own immune responses, which can harm the patient without generating the desired form of protection.

AstraZeneca’s vaccine is recently in phase 2/3 trials in England and India, and in phase 3 trials in Brazil, South Africa, and more than 60 sites in the United States. The company predicted that its US board of directors would be successful by 30,000.

AstraZeneca is one of 3 whose vaccines are in complex clinical trials in the United States.
