Pfizer said Wednesday that new test results show its coronavirus vaccine is 95% effective, is safe and also protects older people most at risk of dying — last data needed to seek emergency use of limited shot supplies even as the catastrophic outbreak worsens across the globe.
The announcement from Pfizer and its German partner BioNTech, just a week after they revealed the first promising preliminary results, comes as the team is preparing within days to formally ask U.S. regulators to allow emergency use of the vaccine.
They also have begun “rolling submissions” for the vaccine with regulators in Europe, the U.K. and Canada and soon will add this new data.
Pfizer and BioNTech had initially estimated the vaccine was more than 90% effective after 94 infections had been counted in a study that included 44,000 people. With the new announcement, the company now has accumulated 170 infections in the study -- and said only eight of them occurred in volunteers who got the actual vaccine rather than a dummy shot. One of those eight developed severe disease, the company said.
“This is an extraordinarily strong protection,” Dr. Ugur Sahin, BioNTech's CEO and co-founder, told The Associated Press.
The companies have not yet released detailed data on its study, and results have not been analyzed by independent experts. Also still to be determined are important questions such as how long protection lasts and whether people might need boosters.
But all eyes are on the progress of potential vaccines as the grim infection rate jumps in the U.S. and abroad as winter weather forces people indoors, in the close quarters that fuels viral spread.
Pfizer and BioNTech said the vaccine was more than 94% effective in adults over age 65, though it is not clear exactly how that was determined with only eight infections in the vaccinated group to analyze and no breakdown provided of those people’s ages.
Sahin said there were enough older adults enrolled in the study and among the placebo recipients who became infected that he is confident “this vaccine appears to work in the higher-risk population.”
Earlier this week Moderna, Inc. announced that its experimental vaccine appears to be 94.5% effective after an interim analysis of its late-stage study.
Similar results from two vaccines both made with a brand-new technology — using a snippet of the genetic code of the coronavirus to train the body to recognize if the real virus comes along — likely will add to experts' reassurance about the novel approach.
While initial supplies will be scarce and rationed, as the supply grows Sahin said the companies have a responsibility to help ensure access for lower-income countries as well.
Pfizer and BioNTech also say now have the required data on the vaccine’s safety needed to seek emergency authorization from the Food and Drug Administration.
The companies didn’t disclose safety details but said no serious vaccine side effects have been reported, with the most common problem being fatigue after the second vaccine dose, affecting about 4% of participants.
The study has enrolled nearly 44,000 people in the U.S. and five other countries. The trial will continue to collect safety and effectiveness data on volunteers for two more years.
Pfizer and BioNTech said they expect to produce up to 50 million vaccine doses globally in 2020 and up to 1.3 billion doses in 2021.
U.S. officials have said they hope to have about 20 million vaccine doses each from Moderna and Pfizer available for distribution in late December. The first shots are expected to be offered to vulnerable groups like medical and nursing home workers, and people with serious health conditions.

Amazon is betting that ammonia could be the fuel of the future, participating in a Series A round for the Brooklyn-based company Amogy in December. Amogy aims to de-carbonize transportation with a clean energy system that uses ammonia as a renewable fuel. Amogy is partnering with Amazon on its first commercial product - an ammonia-powered cargo-shipping vessel. Amogy CEO Seonghoon Woo joins Cheddar Climate to discuss.
Cryptocurrency is expected to become a part of our daily lives — but what sort of environmental impact does it have? As the U.S. becomes the crypto mining capital of the world, climate advocates are worried about mining companies reopening old coal plants, using massive amounts of energy, wasteful hardware, and more. Congressional Democrats led by Senator Elizabeth Warren are demanding answers from mining firms about their electricity use and waste levels. John Belizaire, CEO of Soluna Computing, joins Cheddar Climate to discuss the congressional letters, how crypto mining can become a green industry, and more.
Driver assistance monitoring systems are meant to keep the driver's eyes on the road, but according to a report from AAA, different ways of monitoring provide significantly different results. The study found that direct camera-based systems that scanned the driver's eye movements were faster and more reliable than those indirect systems that looked at steering-wheel input. Megan McKernan, the manager of automotive services for the Automobile Club of Southern California, joined Cheddar to discuss the findings. "Triple-A is recommending that automakers include both direct and indirect systems just to really prevent consumers from trying to misuse these systems," she said, noting that neither system on its own is not foolproof.
Wave Neuroscience is a neurological health tech company that specializes in clinical and at-home personalized brain stimulation technology. Erik Won, president and chief medical officer and Fred Walke, CEO, joined Cheddar's Opening Bell to discuss their company's hopes for allowing patients to identify and treat unique brain disorders while empowering them to understand their unique neurological makeups — including for the high-stress positions of professional athletes. "We have a mobile device that provides a very light stimulation that gives them a therapy that gives them confidence so there's a just knowing that they're doing something for it," said Walke. "But it also helps them get back into a rhythm. It helps their brain synchronize around certain frequencies that that we target, and it helps them really understand that they've done everything they can to get to their highest level of success."
Democratic lawmakers are now calling on Bitcoin mining companies in the U.S. to assess how much electricity they use and how it could all potentially impact residents and the environment in the near future. Since its conception, crypto mining has been at the center of a debate. The question is: Is crypto mining playing a key role in renewable energy or could it totally derail U.S. climate goals? Host of The Wendy O show Wendy O, joined Cheddar to discuss more.
