All’s not OK with Oxford-Astrazeneca-Serum vaccine as claimed

I saw a set of survey questions on vaccine taking in circle. As you answer them pls review this information too. All is not well with the Oxford-Astrazeneca-Serum vaccine. That Poonawala fellow and Indian media kay be claiming victory too early jeopardizing common people. In a significant development, British-Swedish drug maker AstraZeneca and Oxford University on Wednesday admitted a manufacturing error while developing coronavirus COVID-19 vaccine.The acknowledgement by AstraZeneca has raised serious questions over the preliminary results of the company's COVID-19 vaccine as the error made a difference in the trial results. AstraZeneca issued the statement admitting the error days after it described the shots as “highly effective”. It may be recalled that AstaZeneca and Oxford University did not mention why some study participants were not administered as much vaccine in the first of two shots as expected. According to AstraZeneca, the volunteers who were given a lower dose showed much better response than the volunteers who got two full doses. AstraZeneca said that the vaccine appeared to be 90% effective in the low-dose group. AstraZeneca also revealed that the volunteers who got two full doses showed 62% efficacy against coronavirus. AstraZeneca had said that the combined result showed the vaccine is 70% effective. But several experts raised questions over the way which were adopted by AstraZeneca and Oxford Universuty to arrive at these results. On November 23, AstraZeneca and Oxford University had announced that the COVID-19 vaccine being developed jointly by them has shown 70 per cent efficiency. Oxford-AstraZeneca, however, added that the efficacy of vaccine could be around 90 per cent under one dosing regimen. https://www.nytimes.com/2020/11/25/business/coronavirus-vaccine-astrazeneca-oxford.html
