Pfizer Says Their New COVID-19 Vaccine Is 90% Effective
Share
In a press release issued Monday, Pharmaceutical giant Pfizer and BioNTech announced that their COVID-19 vaccine is 90% effective, however they neglect to mention that the sample size is substantially smaller than ideal.
“Today is a great day for science and humanity,” said Pfizer CEO Albert Bourla in a statement. “The first set of results from our Phase 3 Covid-19 vaccine trial provides the initial evidence of our vaccine’s ability to prevent Covid-19.”
But according to VOX: The key words there are “initial evidence.” The announcement is by no means a final result, and the phase 3 clinical trials of the Pfizer-BioNTech vaccine still need to be completed. That will likely take a few more months, and the subsequent findings could undermine the early results.
On the other hand, the recent announcement does hint that Pfizer and BioNTech, as well as some other manufacturers using the mRNA-based approach, are on the right track. That means that by next year, several vaccine candidates may begin distribution.
