Covid-19: Pfizer and BioNTech announce their vaccine is “90% effective”
The results come from the first interim analysis of the phase 3 trial, the last before an application for registration.
New hope in the fight against Covid-19. The vaccine developed by the American Pfizer and the German BioNTech is “90% effective”, the two pharmaceutical companies say Monday, November 9, after the first interim analysis of their phase 3 trial, the last before an application for approval .
Patient protection was achieved seven days after the second of the two doses and 28 days after the first, according to preliminary results.
Caregivers vaccinated before the end of the year?
“More than eight months after the start of the worst pandemic in more than a century, we believe this step represents a significant step forward for the world in our battle against Covid-19,“ said the Chairman and CEO of Pfizer, Albert Bourla, in a statement.
“The first set of results from our Phase 3 Covid-19 vaccine trial provides initial evidence of our vaccine’s ability to prevent Covid-19,“ he adds. Based on projections, the companies said they plan to deliver up to 50 million doses of vaccine globally by the end of the year and up to 1.3 billion doses in 2021.
Pfizer and BioNTech intend to seek authorization for emergency use of their vaccine as early as this month in the United States. They estimate that the three necessary criteria (efficacy, absence of health risk and the ability to produce on a large scale) will be met by the end of the month. This would mean, according to the Guardian (article in English), that members of the hospital staff could be the first to be vaccinated in some countries before the end of the year.
