“90% of the vaccine’s effectiveness is a game changer.“On November 9, after the first results of the phase III trial of the new corona vaccine developed jointly by Pfizer and BioNTech were announced, Albert Bourla, CEO of Pfizer, said in an interview with CNN. “Now we expect to get effective weapons against the new corona pandemic.”
However, Burla said frankly that it is not yet certain how long the protection provided by the vaccine will last. Pfizer will continue to follow all subjects for two years to observe the duration of the immune response.
Furthermore, in a CNN interview, Prank categorically dismissed the political factors at the time the test results were announced. He said the third-party data monitoring committee found the test results at 11:00 on the 8th US time. He didn’t get a call until 2pm. The time to open the blind was in the hands of the scientists. Previously, US President Trump has repeatedly suggested vaccines may be passed ahead of the election and expressed dissatisfaction with the FDA’s stringent vaccine review standards.
Pfizer and BioNTech participated in this study with 43,538 subjects, who were randomized to receive vaccine or placebo injections. At the eighth local time, 38,955 volunteers completed the second injection. The subject of this interim analysis of the results are 94 subjects infected with the new corona. After the data monitoring committee was opened, it was found that less than 10% of the infected people were from the vaccine group and over 90% of the infected people were from the placebo group, indicating that the vaccine is effective for over 90 %. The result of the final analysis will be obtained when the number of subjects infected with the new coronavirus reaches 164.
