The Asian market has responded to criticism from several scientists who questioned the effectiveness of the AstraZeneca vaccine in collaboration with the University of Oxford. Previously this vaccine was said to be 90% more effective.
This scientist's latest view is not without reason. The reason is, there were mistakes made at the beginning. It started when a small group of volunteers received a lower dose of the vaccine accidentally. The result was the vaccine was successful 90%.
But in the larger group with the normal dose, the success rate was even lower, only 62%. Many scientists have interpreted testing in small groups as 'yielding false readings'.
"All you have to do is release limited data," said Peter Openhaw, professor of experimental medicine at Imperial College London, quoted by Reuters, Friday (27/11/2020).
"We have to wait for the complete data and to see how regulators see the results."
This raised the concerns of the Head of Operation Warp Speed (the special team for handling President Donald Trump's corona), Moncef Slaoui. He said the 90% efficacy was shown by the lowest risk group, as many as 2,741 people under 55%.
AstraZeneca CEO Pascal Soriot said the British pharmaceutical giant is likely to run additional global trials to evaluate the vaccine's efficacy, CNBC quoted Bloomberg as saying.
An AstraZeneca spokesman also rejected the scientist's criticism. The company claims that the testing is in accordance with the Data Safety Monitoring Board (DSMB) standard.
Meanwhile, data on China's industrial profits for the period of October 2020 recorded positive growth to the level of 0.7% and away from the previous negative level, namely 2.4%.
