  AstraZeneca halts a COVID-1 vaccine trial due to a participant’s illness.

  The pharmaceutical company AstraZeneca halted global trials of its coronavirus vaccine on Tuesday because of a serious and unexpected adverse reaction in a participant, the company announced.

  The trial’s halt, which was first reported by Stat News, will allow the British-Swedish company to conduct a safety review. How long the hold will last is unclear.

  In a statement, the company described the halt as 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.”

  AstraZeneca said, participants do sometimes become sick by chance, but such illnesses “must be independently reviewed to check this carefully.”

  The company said it was “working to expedite the review of the single event to minimize any potential impact on the trial timeline” and that it was “committed to the safety of our participants and the highest standards of conduct in our trials.”

  A person familiar with the situation, and who spoke on the condition of anonymity, said that the participant had been enrolled in a Phase 2/3 trial based in the United Kingdom. The individual also said that a volunteer in the U.K. trial had been found to have transverse myelitis, an inflammatory syndrome that affects the spinal cord and is often sparked by viral infections. However, the timing of this diagnosis, and whether it was directly linked to AstraZeneca’s vaccine, is unclear.

  AstraZeneca’s vaccine, known as AZD1222, relies on a chimpanzee adenovirus that has been modified to carry coronavirus genes and deliver them into human cells. Although the adenovirus is generally thought to be harmless, the coronavirus components of the vaccine are intended to incite a protective immune response that would be roused again should the actual coronavirus try to infect a vaccinated individual.

  Adenoviruses, however, can sometimes trigger their own immune responses, which could harm the patient without generating the intended form of protection.

  AstraZeneca’s vaccine is currently 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.

  AstraZeneca is one of three companies whose
  vaccines are in late-stage clinical trials in the United States.

  Scientist claim that COVID-19 came from bats and crossed over to humans, now they wish to inject us with a virus derived from monkeys and claim this is safe, despite the potential side effects that can cause. No wonder these pharmaceutical companies and distributors are demanding a guarantee they cannot be prosecuted if people die from their rushed vaccines.

  Would you trust this vaccine?
