On Monday, Pfizer announced a major breakthrough related to its COVID-19 vaccine. According to the NYT, “an early analysis of its coronavirus vaccine trial suggested the vaccine was robustly effective in preventing Covid-19, a promising development as the world has waited anxiously for any positive news about a pandemic that has killed more than 1.2 million people.”

Here are some key notes from various outlets:

New York Times:

“Pfizer, which developed the vaccine with the German drugmaker BioNTech, released only sparse details from its clinical trial, based on the first formal review of the data by an outside panel of experts.

The company said that the analysis found that the vaccine was more than 90 percent effective in preventing the disease among trial volunteers who had no evidence of prior coronavirus infection. If the results hold up, that level of protection would put it on par with highly effective childhood vaccines for diseases such as measles. No serious safety concerns have been observed, the company said.

Pfizer plans to ask the Food and Drug Administration for emergency authorization of the two-dose vaccine later this month, after it has collected the recommended two months of safety data. By the end of the year it will have manufactured enough doses to immunize 15 million to 20 million people, company executives have said.”

StatNews:

“Pfizer and partner BioNTech said Monday that their vaccine against Covid-19 was strongly effective, exceeding expectations with results that are likely to be met with cautious excitement — and relief — in the face of the global pandemic.

The vaccine is the first to be tested in the United States to generate late-stage data. The companies said an early analysis of the results showed that individuals who received two injections of the vaccine three weeks apart experienced more than 90% fewer cases of symptomatic Covid-19 than those who received a placebo. For months, researchers have cautioned that a vaccine that might only be 60% or 70% effective.

The Phase 3 study is ongoing and additional data could affect results.

“I’ve been in vaccine development for 35 years,” William Gruber, Pfizer’s senior vice president of vaccine clinical research and development, told STAT. “I’ve seen some really good things. This is extraordinary.” He later added: “This really bodes well for us being able to get a handle on the epidemic and get us out of this situation.”

CNN:

“Drugmaker Pfizer said Monday an early look at data from its coronavirus vaccine shows it is more than 90% effective — a much better than expected efficacy if the trend continues.

The so-called interim analysis looked at the first 94 confirmed cases of Covid-19 among the more than 43,000 volunteers who got either two doses of the vaccine or a placebo. It found that fewer than 10% of infections were in participants who had been given the vaccine. More than 90% of the cases were in people who had been given a placebo.
Pfizer said that the vaccine, made with German partner BioNTech, had an efficacy rate higher than 90% at seven days after the second dose, which means protection is achieved 28 days after a person begins vaccination. The vaccine requires two doses. The US Food and Drug Administration has said it would expect at least 50% efficacy from any coronavirus vaccine.
In an interview with CNN Chief Medical Correspondent Dr. Sanjay Gupta on Monday morning, Pfizer CEO Albert Bourla called the Covid-19 vaccine “the greatest medical advance” in the world’s last hundred years.
“Emotions are very high. You can imagine how I felt when I heard the results yesterday at 2 p.m. I think that likely, based on impact, this will be the greatest medical advance in the last 100 years,” Bourla said.
“It is extraordinary but it’s coming at a time that the world needs it the most,” Bourla said, noting that the United States has recently seen more than 100,000 daily new Covid-19 cases.

FOX:

Dr. Anthony Fauci, the nation’s top infectious disease expert, said Pfizer’s findings of a coronavirus vaccine candidate that is more than 90% effective were “extraordinary,” per a report.

“The results are really quite good, I mean extraordinary,” said Fauci, director of the National Institute of Allergy and Infectious Diseases, according to the Washington Post.

The company is still awaiting data on safety, which it expects to be made available by the third week of November, according to a press release.
