It is being known that the British–Swedish multinational pharmaceutical and biopharmaceutical company, AstraZeneca and Oxford University acknowledged a manufacturing error related to Covid-19 vaccine study.

According to a PTI report, a statement describing the error on Wednesday came days after the company and the university described the shots as "highly effective" and made no mention of why some study participants didn't receive as much vaccine in the first of two shots as expected.

Notably, at AstraZeneca, the group of volunteers which had lower dose were much better protected than those volunteers who took two full doses.

As per the report, AstraZeneca stated that in the low-dose group, the vaccine was effective by 90%, while in two full-dose group - the vaccine was 62%. Combined, the vaccine appears to be just 70% effective in preventing the virus.

The report said, but the way in which the results were arrived at and reported by the companies has led to pointed questions from experts.
