Corona Vaccine: AstraZeneca admits manufacturing error in trials
AstraZeneca said the vaccine appeared to be up to 90 percent effective in the low-dose group, while the group that was given the full two doses showed the vaccine to be up to 62 percent.
New Delhi: The UK pharma company AstraZeneca and Oxford University have admitted an error in their vaccine trials. This is because those who were given low doses of the vaccine in the test had 90% effect, whereas those who were given two doses were found to have only 62%. However, questions are now being raised about the initial claim of the vaccine being effective.
Effects of AstraZeneca:
AstraZeneca released a statement on Wednesday about the mistake. A few days earlier the company and the University of Oxford had said that the experimental vaccine is highly effective. It was then not mentioned why some of the participants in the study were not given the same amount of doses in the first of the two doses of the vaccine as expected.
Surprisingly, the group of people who volunteered to participate in the study were given lower doses of the vaccine, seem to be better protected than the group who were given the full dose.
AstraZeneca said the vaccine appeared to be up to 90 percent effective in the low-dose group, while the group that was given the full two doses showed the vaccine to be up to 62 percent. Overall, the drugmaker said the vaccine appears to be up to 70 percent effective.
What experts say?
But the way in which the results reached and the companies have given information, the experts have raised questions. Partial results were announced on Monday, which are part of a larger study going on in Britain and Brazil. The best vaccine dose will be found out in it. Simultaneously the safety and effectiveness of the vaccine will also be tested.
