In the first week of September, the pharmaceutical company AstraZeneca, which is developing a Covid-19 vaccine in collaboration with the University of Oxford, halted the trial process when two participants who participated in a trial developed an adverse impact. After this, the trial was stopped in other countries, raising concerns about the safety of the vaccines. The trials began after the UK government gave the vaccine the green light. Trials also started in India, Brazil. However, the US authorities have not yet resumed the trials. Then a volunteer died in Brazil. But the trial does not stop.
This is everything you need to know about the most recent case:
one. Details of the vaccine trial participants are confidential information. The details of the disease, if it could develop, are also not revealed. Brazilian newspapers reported that the person was a 28-year-old doctor who worked with Covid-19 patients.
two. Reports suggest that the person was enrolled as a participant in the ongoing trial. But no candidate vaccine has yet been administered.
3. Therefore, the trial has not stopped. “All major medical events are carefully evaluated by the trial investigators, an independent safety monitoring committee, and regulatory authorities. These evaluations have not raised any concerns about the continuation of the ongoing study, ”said AstraZeneca.
Four. But such news generates fear among the people.
5. Johnson and Johnson, which is producing millions of vaccine injections in the United States, stopped its trial because a participant reported an unexpected illness.
So far, three vaccine trials have been briefly stopped. Aside from AstraZeneca (resumed elsewhere besides the US) and Johnson & Johnson, Eli Lilly’s trial of antibody treatment was stopped after the adverse report. However, experts believe that stopping the trials shows that vaccine manufacturers are acting with extreme caution.
